I am glad there are people that take the time to make videos like this to help others learn. I love watching your videos and have learned quite a bit from them. Thank you for doing what you do!!
Best tutorial available anywhere. If you're having issues with getting your printer working, just get the hardware that you see in this video and follow along. Chris is going step-by-step which might seems unnecessary but if you're new to 3d printing it's very much appreciated. Keep up the good work Chris!
I'm 74 years young and brand new to this, Chris has been a lifesaver! He does talk a little fast but I know how to back up and play it over again. My new BTT SKR is working great, now on to his other video on how to add a BL touch. Thank you very much Chris.
Just put my SKR v2 in my Ender 3 Pro, The drivers are CRAZY SILENT with these step motors and it runs SOOOO much smoother and faster. I was super concerned about building a new firmware for my board but this tutorial was perfect and taught me a TON!!!! Such a great upgrade. Gonna put in my BLTouch tomorrow or sometime next week, I also have the FTF70 7" touchscreen to do but wanted to get this installed and the machine speed up so when I print the casing it doesnt take me forever and I get the best quality. For now this get the thing running flawlessly!! Thanks again.
Possibly the best video on the SKR Mini E3 V2. You get right to the point. Got this board last week and added this and the TFT35 V3 to the ender 5 plus. Got 2 very minor issues related to re configuring a pin for an extra fan and hotend trying to move beyond the the beds x/y bounds. Think this tackles the re configuration issue. Will give that a try later.
@@ChrisRiley This was a huge help in figuring how to edit the configs and compile everything. One thing I did different was in platformio.ini, I had to change default_envs to "STM32F103RC_btt_512K" instead of "STM32F103RE_btt".
Chris your explanation is outstanding. I'm waiting for my Ender 5 to arrive & ordered the SKR V2.0 board with it. I am a completely new to 3D printing this will be my first time & gotta say its a bit intimidating having to config things at this level. Watching most videos has left me a bit confused, esp since I have never used Github before & your style of explanation has given me way more confidence - much appreciation, well done!
For some reason, our channel got a bunch of comments recently that are over a year old. I hope you got your issue solved. We didn't purposely ignore you. Thanks for watching!
@@ChrisRiley Sooo, got the CR-10s up and running with the BTT SKR mini V2.0 and it won’t read from the SD card. I’m able to load the firmware via the SD, but I can’t load a gcode file to print from - doesn’t show the option on the screen. Any tips of where to look at? I have to use Pronterface to print from.
@@ChrisRiley it does - used it in my laptop and loaded through Pronterface. Tried other cards and tried reformatting. Right now I have Octoprint connected so I don’t have to use the usb slot. At least I can load firmware through it, though. Thanks.
Super job with the video! My new BTT SKR board arrived today and this video included everything I needed to get it running and then add my own settings and adjustments to my customized Ender 3 printer.
Chris you films are the best man, the detail of description is grate (THANK YOU). I wish I had gone for the v2.0 board instead of the v1.2 board just for the FAN1_PIN control, cant control it on the 1.2 board
Just ordered the board and touchscreen combo. This was the best video covering Marlin. I've done 1 Marlin config 32bit board before, but I needed a serious refresher. Lol I'll have to tweak my E steps, turn on Auto PID function because it's so handy, set bed size to 235x235, tweak BLtouch probe offset from nozzle, and that should be about it.
First of all, thank you for the installation guide, took me a while but got it done. Second, wow. Wow those drivers make the motos illegally quiet, I knew the difference would be big but I didn't think that it would drop the steppers noise below that of the stock fans, guess I need to upgrade those too now.
Thank you for taking the time to explain this stuff. Very well explained. You are awesome. Thank you for taking the time to explain this. Stay healthy brotha!
Chris, the fan pins you used for the hot end are setup for the MB fan, It’s is controlled by firmware but the reason it came on is during any movement by the steppers the MB fan comes on which was always on on the 1.2. My hot end fan is on all the time with the constant power setup...cheers as I got further in the video I saw you figured it..
Thanks for the walk through. I got to building Marlin in PlatformIO and it complained that STM32F103RE_btt was not compatible, recommended using STM32F103RC_btt which built successfully. Not sure what the difference is ...
Question for you. Thank you!! :) So I have spent the better part of the last 24hrs trying to troubleshoot my 3Pro to the point ordered a 2nd BLTouch for troubleshooting. I swapped out the Creality 4.2.7 for the Mini E3 with their touchscreen combo I got from Amazon the other day. Z would not home at all, just sit there are deploy/retract the BLTouch needle a few times then timeout. Watched this video combined with your BLTouch one and I obviously was missing something before because now it is working again! You are going to be my first stop from now on, for troubleshooting. I am so happy right now, you have no idea. THANK YOU !! :)
Cheers Chris. If I'd actually seen the fan cover mod, I wouldn't even be doing this! The reason I bought the board was because I dropped a couple of nuts in the fan (Didn't realise that's where they'd gone) whilst doing a fan upgrade on the hot end. Said nuts fell through the fan and shorted the OEM board when I turned it on.
Great video as always Chris. I wonder how you got a hold of the hemera hotend. I wonder if it is as great as i hope it is. I want to replace all my printers cuz im sock and tored of leaking v6 hotends.
@@ChrisRiley have you had any problems with it leaking? This is a notorious problem on my prusas with v6 hotends. I have done all the tricks on the web but they still leak a bit.
4:58 At first I laughed about sensorless homing on E, but then I started to wonder if it would be possible to go full mad scientist in Marlin and use it as a stop for automatic filament loading. Unfortunately I suspect the sensitivity tuning might kill the (stupid) idea.
Thank you for the Video ! Do you know Why the bedleveling is not saving the values? After a succsesfully bedleveling the nozzle during the printing is away up from the bed.
@@ChrisRiley hi Chris I tried to install this in a cr10S (if anyone reading this you need to make sure you order a cable that combines the 2 lcd cables in to 1) and I have 4 fans - the parts cooling fan the extruder fan the case exhaust fan and a fan thats directly in front of the lcd board, where can I connect the two extra fans? You explained that I can connect one to the constant voltage ( which I'm my case means disconnecting the connector currently attached to the cable) but where can I fit the 4th one? Thank you in advance
@@ChrisRiley yeah but then I'm left with one fan disconnected, does the pwr-on port in this board is suitable for connecting one of the fans? I've seen someone connect it via this method but I don't want to harm the board accidentally.
Quick warning. Just did this exactly how Chris did it. Found out that the colors for the hot end thermistor and heated bed were swapped. To avoid any problems, do the following: 1. Once configured, set the heated bed to 50c and feel it for any temp change. 2. If it does not change in temp or it shows the temperature of the nozzle increasing, simply swap the connections and repeat. Don't just assume that the wiring is correct like I did. Made the mistake and my heated bed started increasing in temperature almost immediately. Error was given and had to swap the wires. Fixed the issue. Just wanted everyone to know.
Hi there Chris! I found your channel when I ordered this board a couple of weeks ago. Great stuff you got going here. Keep up the good work! Now to my question. How high do you think I can crank up BUFSIZE? I'm running Octoprint and I know there's been a lot of discussions about this. I got a CR-10 Mini with everything stock except for the board now.
BUFSIZE to baudrate and all that, I am not really sure, that would be a question for the Marlin gurus. The Marlin discord folks will be able to answer that.
Getting pretty frustrated trying to build my bin file as each time I try I just get FileNotFoundError: [WinError 3] The system cannot find the path specified - Any tips on getting past this?
I do have a question though, what do you consider or what did I say to Max temps are for the hot end in the bed? And then what kind of increase can you get on that by breaking off the MOSFETs?
So it's really not about max temp as far as the board goes, the hotends, you see 50w heaters, about any mosfet will run it. Now beds, you can really only expect to get around 120c max on DC, and if it's over about 220x220 the load can get really high, above 11amp. That is where you need to look at the loads and consider moving that to an external mosfet. I would have to look up the chip numbers to tell you max load. A lot of us go to AC beds for this reason.
Yo man! Great video! I love how you showed how to use PWM for the hot end fan to turn it off below 50c! I love it on my machine! Thanks man, love every videos you've made!
Hi again chris it has been several years, I had changed out all of my ender 3s and cr 10's with the skr mini e3 v2.0 and the tft 35 with a bl touch ever thing worked out great with your help. NOW for the question what do I need to do to change the marlin set up to clipper without changing any hardware I called myself checking out your videos but I did not find anyone pertaing to this setup if you did just please direct me to the video so I can do it After getting a k1 max and seeing the speed and accuracy I have seen your video about BIGTREETECH SKR Mini E3 V3.0 Again if you don't have time to answer I do understand again thanks oldfarmhand
I have an Ender 3, which I have had for a number of years. It is a great printer and has served me well so far. I have been running it with the stock Ender main board & using MatterControl, as I like the ability to send send files directly to the printer, from the computer and to be able to control the printer while it is operating. I recently changed the main board to this one, as the Ender board finally crapped out. Now my computer does not recognize / cannot find the Ender 3. Any ideas / suggestions / thoughts / comments?
@@ChrisRiley It is installed. I removed it and reinstalled it. Still the same thing. When I plug in the Ender 3, the computer makes a funny sound, the Ender 3 Screen lights up and says 'TMC Connection Error' at the bottom.

Thanks for the detailed explanation. This is super helpful. If I'm not adjusting the speed of my hotend fan and the rest of my ender3 is stock, are there any changes that I have to make for the v2 board?
While I'm waiting for my new board to arrive, watched like 5 times this video. It is so helpful, thanks for that! Can I ask about your aluminum heated bed? It seems to have a PEI sheet right? No removable. Correct me if I'm wrong. I'm interested in that too! Thanks again, big fan from Argentina.
Thanks Very informative ! I hope that maybe in the future when you discuss the BL Touch setup you discuss in the configuration you will talk about configuration adv. h with the bl touch setup Thanks
Chris, I was looking on Amazon US at this board as someone told me it was cheaper to import a board from the US to the UK than it is to buy from the UK and I saw the seller says " 2)Because the fan on the SKR Mini E3 V2.0 control board is a CNC fan, you need to set the wind speed before using it. (Note: V2.0 version of the fan is not ready to use after power on);" I can't find anything about this on the web, what is your take on this?
Hi Chris this a little bit off topic but you helped me so much with my ender 3 now I have a question about my cr10 :-) I am going to change out the main board to a mini e3 v2.0 like I did on my ender 3 but not sure about the marlin 2.0 setup for it, if i used the setup from the ender 3 what do you suggest i change, for it to be compatible? I use your setup with bl touch settings and it the ender 3 works great! Again Thanks
Hey, that will be a super simple change. Those machine are very similar. I would just increase bed size and Z height to match the CR10. You might what to lower the acceleration a bit because of the heavier bed, but the rest should work fine.
Great video. But I have an Ender 3 Max. Following the part about compiling the firmware, and using the Ender 3 Max folder in the Examples folder (rather than the Ender 3) I am not seeing a folder for the SKR Mini E2 v2.0. I am just seeing 4 files...2 configs and 2 screen files. How can I create firmware for my Max if the folder isn't there?
You say Fan0 (PC6) in controlled by default?.... that is where the the original (creality) blue/yellow wires go, correct? I have no control over the part cooling fan when connected there. It stays on permanent and no control from the console either. With the v1.2 board it does control the part cool fan without any issues. It seems like I'm finding a lot out there with the same issue.
Quick note Chris on the TFT touch display if the Black cable is inserted on the wrong slot on the screen end it will give Heatbed Temp fluctuations, I did have it on the wrong slot and it happened on my Ender 3, swapped it to the correct position and it went way, awesome little board with many features.
Hi I am now in building a printer looks like Anycubic how do i put Endstops on it the most of the Endstopswitches have 3 Cable so it is not possible to stick it in the Mini E3 2.0 because there are just two connect pins please explain how its done keep your good work in futere
hi Chris watched a lot of your videos and you inspired me to build my own printer with the e3v2 but i dont know which board to select in platformio could you help me please
OK Chris, fan question, fans are, case fan, hot end fan and part fan- on my OEM Ender 3 board i have stripped wires that go on teh screw terminal beside the main board power and my other 2 clipped on the board. i follower your video to set the fan in the code (FAN1_PIN) with the set value of 50 like you.. but can I still do that with putting my wires back in the screw terminal ( which you didn't ) as you have another setup, or should I splice the board connector to go on the hotend fan and then constant the case fan to the constant power... ugh
Chris - Compiled build environment is INCORRECT in this video at 19:05 - You should be in the 'env:STM32F103RC_btt' environment-C as in Charlie, NOT env:STM32F103RE_btt - E as in Echo as you are in this video for the SKR Mini E3 V2.0.
@@ChrisRiley Ordered, Thanks Chris. Does the board have more than 256K? When I compile in Platformio with STM32F103RC_btt I get the error message "not enough memory". Does it work with version STM32F103RC_btt_512k According to the data sheet, the RC only has 256K I like your tutorials very much. Keep it up.
@@herr_rossi69 I am not sure what''s up with that. I think it's the chip maker safe guarding themselves with that memory limit. It will in fact let you use 512, I have had not problems with it.
@@ChrisRiley You get more than you pay for, even rarely If the board works well I'll buy the 35 touch display. Do I have to change anything in the firmware? I cannot use the BTT firmware because I have a Titan extruder and have to change the direction of rotation.
Even if they don't have the direct port you can use an adapter, and it should just be a setting in marlin. But we will wait for the professional to answer :-) lol
I have a problem with the connection of skr E3 mini v2.0 and cura. Connecting to a computer freezes the printer. Only connecting to another program allows you to control the ender as a repiter host.
Installed my v2 using this video, thank you. I do have a problem though, on the menu I have no bed leveling, how do I get this back onto my menu to enable manual bed leveling via mesh and/or corners?
Hello Chris, I just love your channel, thank you. I am curious, I have an Anycubic Kossel Plus printer. Can I change the Trigorilla board to a SKR Mini 3e V2.0? I really like the board since I just recently changed the board on my Ender 3. Thank you for your assistance. Dusty
Question...i have followed this video 10 times. reloaded new version of Marlin from the Github site. I have 2 problems. 1 When I reboot with the new firmware I get an error the error " failed to enable bed leveling" From what I have read, that is because there is no data. So the second problem. Homing, Everything seems to work when going to home, X & Y go home, the extruder goes to the middle of the bed, but the Z will not go down. it moves upwards, then stops. the BLTouch does it quick reset, probe extends and then I get an error "STOP called because of BLTouch error, Restart with M999" Any help from your user or you would greatly be appreciated. Thanks in advance...CO
My guess is that it thinks the Z is always triggered. Check it with m119. Check you white and black wires are on the S and G pins. Try switching these marlin settings. #define Z_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Z_MIN_PROBE_ENDSTOP_INVERTING false // Set to true to invert the logic of the probe.
so this has 2 z plugs, but only one tmc chip between them? so not a great upgrade from a 1.2, but with a splitter cable - i'm assuming you cant control them independantly?
Hey Chris, What is the solution for Nozzel Heat overshoot. for example, I set temp to 200 it will go up and pass 230 then start going down again. I tried to do the PID tuning But failed due to the problem I mentioned above, can you please help with this matter. using BTT SKR Mini E3 V2.0 I check all the wiring and for sure has nothing to do with that. totally new to this and thanks to you I'm learning so much. appreciate your help.
So PID is really all you can do here. Silicon socks can help as well. Try to set you PID auto tune to 210 and reset those numbers in eeprom. Preheat to 210 also before you start the autotune. I would check your PSU voltage too, make sure it's not too high.
I just received mine and I did a complete swap wire by wire so I don't mess up, When I plug the screen it beep and the screen get turn on and off, but when the screen is not connected everything seems to work until you see smoke coming out of the board, what the hell !?!? please help
@@ChrisRiley Thank you for the reply and yea the board was defective. No doubt in my mind that this is Canada poste fault. It took me 4 weeks to get my board
Chris, this works great for me, but how can I export the firmware file to the server card, tried a direct connection but VNC studio rejects it, how do I export the firmware file so I can upload it via sd card?
On the STM32 there is no way to do it from the serial I am afraid, you have to hand truck it with the SD card. The STM chip takes some sort of interpetur to flash it.
Those are ferrules you use them under terminals. www.amazon.com/Ferrule-Crimping-Tool-Kit-0-08-10mm%C2%B2/dp/B07K17VDF2/ref=sr_1_2_sspa?dchild=1&keywords=ferrules&qid=1600891909&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFROExSNzNLWVpGRTgmZW5jcnlwdGVkSWQ9QTAyMDk0NTkyWllPQjROWklLME5RJmVuY3J5cHRlZEFkSWQ9QTA5MDcxMDAxMUE3SVNQS05UMVNQJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Would it be beneficial to go dual z with this board on an Ender 3? Possibly make a guide on it since it looks like a simple upgrade to do with this board?
I don't see the point on why you did all that procedure for the fan (swapping the connections, swapping the pins in Marlin etc.). I mean: you're still going to have only one Marlin-controlled fan and the other one full-blown. Thus, the overall noise won't be reduced. So, why u did that?
@@ChrisRiley Ok, now I see the point! Thus, I followed your guide and I have inverted the two fan connections on the controller board. Now the hotend fan is Marlin controlled while the controller fan is always on at full speed. But I replaced the latter with a very quiet 40x40x20mm Noctua fan and since I'm sharing the rear case with a Raspberry, I think it's ok to have the fan always on (perhaps I could GPIO contol the fan from the Pi?). Not a life changer while printing, but much more comfortable while idling at least. Tnx allot for your suggestion! :)
i got my board and the lcd output is keyed torwards the outside instead of the inside like in the video. the lcd wont turn on either. im so new to switching parts that i cant tell if i did something wrong or if my board is bad
Hello Chris, i have a question. I've installed this board on a CR10-Mini. It was running an SKR 1.4 Turbo before (temporarily since i didn't want to cut up the control box for SD and USB), and it was fine, nothing weird going on. However i had a bunch of issues with the Mini E3. The steppers were receiving the wrong commands. For example X was behaving like Z both in terms of Hybrid Threshold and steps/mm, Z was behaving like either X or Y (couldn't quite tell) and Y seemed to behave like the extruder and got hot AF, even though they were all wired correctly. I didn't want to start from the Ender 3 config and change it for my machine, rather i started from the stock Creality config and changed it for this board. After a day of troubleshooting i found some settings in Marlin that would allow me to get them running proprely (X_SLAVE_ADDRESS 0, Y_SLAVE_ADDRESS 2, Z_SLAVE_ADDRESS 1, E0_SLAVE_ADDRESS 3) and the "best part" is i couldn't find anything regarding the issue on the internet. I still have one nagging issue though. My part cooling fans (i have 2 5015 in parallel and a Noctua 40x20 for the hotend heatsink on a Hero Me Gen5) are buzzing. Sounds like PWM noise, but it's really annoying and loud. Sounds almost like a small speaker. They seem to only buzz below 75%, or maybe it's just the fan noise that masks it at 75% and above, but it didn't seem like it, i tried listening carefully. I don't know about the heatsink fan since i always run that at 100% and it's basically dead silent. I had tried enabling FAST_PWM_FAN in Marlin (Configuration.h) since the description seemed to suggest i might fix my issue, however it doesn't seem to be supported for that chip yet. My question is, do you think this is a "bug" with the board, maybe related to the fact it's running 12v and not 24v (even though it can run in both and they also state it supports the CR10 Mini and original CR10 which are both 12v) or a config issue or a hardware issue on my side (fans or wiring) ? Have you installed it alongside a 12v PSU or encountered this issue with any of your machines ? Curious if maybe you know of a solution for this. Needless to say, neither of these issues presented themselves on the SKR 1.4 Turbo...
I think it might be a bug on the board, I haven't tried these on 12v yet, but I can almost guess that it has something to do with the new regulator on the board they are using. Not sure what the fix would be.
I've had the exact same issues... I just fixed the steppers by comparing the configuration_adv.h with the official marlin branch with the broken one from BTT (the current BTT branch doesn't compile) and from there change stuff to copy the BTT branch. As for the PWM noise. I feel like it's hardware related and seeing that the only major change from V1.2 is the 5V regulator it would seem like a logical source... I run on 12V but it really shouldn't make a difference from running on 24V, if anything the datasheet says the regulator is more efficient at 12V. I think i'll check it out with an oscilloscope next friday and try to figure out were the noise is coming from.
@@crookedtooth6445 I'd also be very interested in your findings. I have long since fixed my steppers, infact they were already fixed when i had posted this. As for the fans, i used SOFT_PWM in Marlin and they're definetly quieter. No longer do i have the annoying electrical whining, however now i've got clicking noise when it pulses at low frequencies (i.e. when you're running the fan slowly)... Could probably tune it by messing with the scale, but it eats into the range of PWM that you can use from what i understood. Anyway, haven't touched the printer in a week or so since i've been very busy with work and other things as of late.
It's designed to line up with the ender 3 case, but I am guessing the ender 5 is the same. Check the github drawing. github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/hardware/BTT%20SKR%20MINI%20E3%20V3.0.1/Hardware
Would you now why on the most recent software revision on the skr v2 it's not giving me an option to release the sd card is there a way to ad that in the firmware?
@@ChrisRiley before I updated It would give me the option at the bottom of the tft35 to release and re insert the SD card from the main board the update changes it to change hardware but it won't do anything unless I change over to touch screen mode and then it will let me release the SD so it doesn't get corrupt il try and make a video luckily I never deleted the pre-configured file and just added (.Bin) to the end of it and re flashed
I have all my settings set how I’d like in my firmware for the V1.2 board. However I decided to buy the V2.0. Can I just throw my old firmware for the V1.2? or do I need to do it all over again with the version of marlin that preconfigured for the skr mini e3 v2.0?
Also I don’t want to use my z stop. I took it off and i don’t know where it went. I want to use my bl touch as z min end stop. How would I hook up the bl Touch on the board?
So just use the same firmware but update the board name to 2_0. Bltouch, just leave the red,orange,brown wires on the probe pins and move the black and white wire to the Z min endstop. Make sure white is on S and black is on G.
I am working an making an infinity printer with this board. For convince I'm trying to switch the Y-Stepper port with the Z-Stepper ports in the v2 marlin firmware so I can utilize the 2 ports the Z has. I can't find any way to switch them, so I was wondering if you know if this is possible or not? Thanks!

as usual a nice video. I use your videos as tutorials for people here whenI want them to learn the basics. Thanks for that.
That's what I'm here for. Spread the knowledge!
Chris Riley thanks for that. Makes the community a better place.
Once again, this and your BLTouch video was a huge help in setting up my new CR-10s. Thanks!
Great to hear! Thanks for the comment.
@@ChrisRiley Sooo, got the CR-10s up and running with the BTT SKR mini V2.0 and it won’t read from the SD card. I’m able to load the firmware via the SD, but I can’t load a gcode file to print from - doesn’t show the option on the screen. Any tips of where to look at? I have to use Pronterface to print from.
@@hawker800mech So does the card work at all? Only thing I can think of is try another card or format the card again.
@@ChrisRiley it does - used it in my laptop and loaded through Pronterface. Tried other cards and tried reformatting. Right now I have Octoprint connected so I don’t have to use the usb slot. At least I can load firmware through it, though. Thanks.
Super job with the video! My new BTT SKR board arrived today and this video included everything I needed to get it running and then add my own settings and adjustments to my customized Ender 3 printer.
Sweet! I'm glad it was helpful
This got me sorted from start to finish, thank you!!! 👍🏻👍🏻
Great! Thank you
I don’t understand how this channel has only 35k subs....., keep up the good work!
Thanks!
this is the best and most comprehensive vid for the installation. appreciate u bossman
Thank you!
Chris you films are the best man, the detail of description is grate (THANK YOU). I wish I had gone for the v2.0 board instead of the v1.2 board just for the FAN1_PIN control, cant control it on the 1.2 board
Thanks man, yeah, that is a big improvement for sure.
Just ordered the board and touchscreen combo. This was the best video covering Marlin. I've done 1 Marlin config 32bit board before, but I needed a serious refresher. Lol
I'll have to tweak my E steps, turn on Auto PID function because it's so handy, set bed size to 235x235, tweak BLtouch probe offset from nozzle, and that should be about it.
Awesome, thank you!
First of all, thank you for the installation guide, took me a while but got it done. Second, wow. Wow those drivers make the motos illegally quiet, I knew the difference would be big but I didn't think that it would drop the steppers noise below that of the stock fans, guess I need to upgrade those too now.
Lol! If it ain't one thing, it's another! Thanks for watching
Fantastic video. Answering questions that are constantly spammed/asked across many forums. Thank you !
Great to hear! Thank you
Thank you for taking the time to explain this stuff. Very well explained. You are awesome. Thank you for taking the time to explain this. Stay healthy brotha!
Thanks for watching!
Great job on this video. like the comparison at the end to the Ender 3 V2.
Thanks for watching
Chris, the fan pins you used for the hot end are setup for the MB fan, It’s is controlled by firmware but the reason it came on is during any movement by the steppers the MB fan comes on which was always on on the 1.2. My hot end fan is on all the time with the constant power setup...cheers as I got further in the video I saw you figured it..
Thanks, yeah I got it sorted, but that is an interesting feature.
Thanks for the walk through. I got to building Marlin in PlatformIO and it complained that STM32F103RE_btt was not compatible, recommended using STM32F103RC_btt which built successfully. Not sure what the difference is ...
Really the only difference is the RC is forcing it to use 512k, not sure how that all works, but I always use RC now.
Question for you.
Thank you!! :)
So I have spent the better part of the last 24hrs trying to troubleshoot my 3Pro to the point ordered a 2nd BLTouch for troubleshooting. I swapped out the Creality 4.2.7 for the Mini E3 with their touchscreen combo I got from Amazon the other day. Z would not home at all, just sit there are deploy/retract the BLTouch needle a few times then timeout. Watched this video combined with your BLTouch one and I obviously was missing something before because now it is working again!
You are going to be my first stop from now on, for troubleshooting. I am so happy right now, you have no idea. THANK YOU !! :)
Awesome, glad it helped you out!
Cheers Chris. If I'd actually seen the fan cover mod, I wouldn't even be doing this! The reason I bought the board was because I dropped a couple of nuts in the fan (Didn't realise that's where they'd gone) whilst doing a fan upgrade on the hot end.
Said nuts fell through the fan and shorted the OEM board when I turned it on.
Oh man! I'm glad you got it fixed!
Great video, ordered some upgrades for my Ender 3's but those Heatsinks SO CROOKED!
Admiral, Thanks for the great video!
Lol... Thanks, it was a field promotion.
You know I am so surprised a GUI for firmware configuration has not been written.
We should see one from Marlin really soon.
I've been saying the same thing. Why isn't this easier?!
Great video as always Chris. I wonder how you got a hold of the hemera hotend. I wonder if it is as great as i hope it is. I want to replace all my printers cuz im sock and tored of leaking v6 hotends.
I got mine over at PrintedSolid, they are back in stock. I really like it and it's pretty affordable.
@@ChrisRiley have you had any problems with it leaking? This is a notorious problem on my prusas with v6 hotends. I have done all the tricks on the web but they still leak a bit.
@@EspenShampoo25 I would say about the same as the V6.
4:58 At first I laughed about sensorless homing on E, but then I started to wonder if it would be possible to go full mad scientist in Marlin and use it as a stop for automatic filament loading. Unfortunately I suspect the sensitivity tuning might kill the (stupid) idea.
It's a great idea, not sure how well it will detect with that gear, but it could be fun to try.
Thank you for the Video ! Do you know Why the bedleveling is not saving the values? After a succsesfully bedleveling the nozzle during the printing is away up from the bed.
That is usually the Z offset that caused that. If will need to be adjusted after the bed level is ran.
Will this work on the CR-10S
I second this question
It should yes, but it will need some firmware tweaks.
@@ChrisRiley hi Chris I tried to install this in a cr10S (if anyone reading this you need to make sure you order a cable that combines the 2 lcd cables in to 1) and I have 4 fans - the parts cooling fan the extruder fan the case exhaust fan and a fan thats directly in front of the lcd board, where can I connect the two extra fans? You explained that I can connect one to the constant voltage ( which I'm my case means disconnecting the connector currently attached to the cable) but where can I fit the 4th one? Thank you in advance
@@eranhp Ah, I wasn't aware there was a 4th fan. About all you could do would be to splice one into the power input and let it run all the time.
@@ChrisRiley yeah but then I'm left with one fan disconnected, does the pwr-on port in this board is suitable for connecting one of the fans? I've seen someone connect it via this method but I don't want to harm the board accidentally.
Thanks Chris, this helps a ton with my upcoming printer upgrade. Two thumbs up and keep up the good work!
Glad it helped! Thanks for watching
Quick warning. Just did this exactly how Chris did it. Found out that the colors for the hot end thermistor and heated bed were swapped. To avoid any problems, do the following:
1. Once configured, set the heated bed to 50c and feel it for any temp change.
2. If it does not change in temp or it shows the temperature of the nozzle increasing, simply swap the connections and repeat. Don't just assume that the wiring is correct like I did. Made the mistake and my heated bed started increasing in temperature almost immediately. Error was given and had to swap the wires. Fixed the issue. Just wanted everyone to know.
Thanks for posting this info.
Hi there Chris!
I found your channel when I ordered this board a couple of weeks ago. Great stuff you got going here. Keep up the good work! Now to my question. How high do you think I can crank up BUFSIZE? I'm running Octoprint and I know there's been a lot of discussions about this. I got a CR-10 Mini with everything stock except for the board now.
BUFSIZE to baudrate and all that, I am not really sure, that would be a question for the Marlin gurus. The Marlin discord folks will be able to answer that.
Getting pretty frustrated trying to build my bin file as each time I try I just get FileNotFoundError: [WinError 3] The system cannot find the path specified - Any tips on getting past this?
Make sure you have the folder that contains the Marlin folder added to your project. You should be able to see the .pio folder.
Who gives Chris these promotions? He's an admiral now! Excellent video
Thanks! My wife refuses to call me Admiral. I guess I lose the title when I come up from the basement. 😉
As always great video, however why are you using the STM32F103RE_btt when your Chip is the STM32F103RTC6?
Thanks, honestly, I didn't look. Both will work, but yes, you should go with the one closes to the exact chip.
I do have a question though, what do you consider or what did I say to Max temps are for the hot end in the bed? And then what kind of increase can you get on that by breaking off the MOSFETs?
What did it say* sorry I dictated that and should have checked first lol
So it's really not about max temp as far as the board goes, the hotends, you see 50w heaters, about any mosfet will run it. Now beds, you can really only expect to get around 120c max on DC, and if it's over about 220x220 the load can get really high, above 11amp. That is where you need to look at the loads and consider moving that to an external mosfet. I would have to look up the chip numbers to tell you max load. A lot of us go to AC beds for this reason.
Yo man! Great video! I love how you showed how to use PWM for the hot end fan to turn it off below 50c! I love it on my machine! Thanks man, love every videos you've made!
Thank you so much!
Hi again chris it has been several years, I had changed out all of my ender 3s and cr 10's with the skr mini e3 v2.0 and the tft 35 with a bl touch ever thing worked out great with your help. NOW for the question what do I need to do to change the marlin set up to clipper without changing any hardware I called myself checking out your videos but I did not find anyone pertaing to this setup if you did just please direct me to the video so I can do it

I have an Ender 3, which I have had for a number of years. It is a great printer and has served me well so far. I have been running it with the stock Ender main board & using MatterControl, as I like the ability to send send files directly to the printer, from the computer and to be able to control the printer while it is operating. I recently changed the main board to this one, as the Ender board finally crapped out. Now my computer does not recognize / cannot find the Ender 3. Any ideas / suggestions / thoughts / comments?

Thanks for the detailed explanation. This is super helpful.
If I'm not adjusting the speed of my hotend fan and the rest of my ender3 is stock, are there any changes that I have to make for the v2 board?
No, it should be a direct swap out, no changes needed.
@@ChrisRiley thanks!
While I'm waiting for my new board to arrive, watched like 5 times this video. It is so helpful, thanks for that!
Can I ask about your aluminum heated bed? It seems to have a PEI sheet right? No removable. Correct me if I'm wrong. I'm interested in that too!
Thanks again, big fan from Argentina.
Correct, it's just a PEI sheet, not removeable.
Thanks Very informative !
I hope that maybe in the future when you discuss the BL Touch setup you discuss in the configuration you will talk about configuration adv. h with the bl touch setup
Thanks
Will do, I will make a note of that.
@@ChrisRiley please do :)
Chris, I was looking on Amazon US at this board as someone told me it was cheaper to import a board from the US to the UK than it is to buy from the UK and I saw the seller says " 2)Because the fan on the SKR Mini E3 V2.0 control board is a CNC fan, you need to set the wind speed before using it. (Note: V2.0 version of the fan is not ready to use after power on);" I can't find anything about this on the web, what is your take on this?
Not sure what they mean by that. FAN0 is controlled by gcode, so it shouldn't be an issue.
Hi Chris this a little bit off topic but you helped me so much with my ender 3 now I have a question about my cr10 :-)
I am going to change out the main board to a mini e3 v2.0 like I did on my ender 3 but not sure about the marlin 2.0 setup for it,
if i used the setup from the ender 3 what do you suggest i change, for it to be compatible?
I use your setup with bl touch settings and it the ender 3 works great!
Again Thanks
Hey, that will be a super simple change. Those machine are very similar. I would just increase bed size and Z height to match the CR10. You might what to lower the acceleration a bit because of the heavier bed, but the rest should work fine.
@@ChrisRiley Thanks for the info, I was not sure about the 3d touch sensor
Great video. But I have an Ender 3 Max. Following the part about compiling the firmware, and using the Ender 3 Max folder in the Examples folder (rather than the Ender 3) I am not seeing a folder for the SKR Mini E2 v2.0. I am just seeing 4 files...2 configs and 2 screen files. How can I create firmware for my Max if the folder isn't there?
Thanks! I would just use the Ender3 and make the quick updates for the max sizes.
You say Fan0 (PC6) in controlled by default?.... that is where the the original (creality) blue/yellow wires go, correct? I have no control over the part cooling fan when connected there. It stays on permanent and no control from the console either. With the v1.2 board it does control the part cool fan without any issues. It seems like I'm finding a lot out there with the same issue.
Yes, fan 0 should be your controllable part fan, you have it correct. I guess it's a board issue. That is sad to hear.
I use it on my Ender 5 with TFT3.5! It‘s amazing and after some problem it works perfect!
That's great! Thanks for watching
Dude , to install wifi module is via tft35 screen interface?
For a mini board, yes.
Why did it look like your hot-end fan and heated bed terminals were wiggling as you were touching them with your screwdriver? That doesn't seem safe!
Sometime those terminal aren't the sturdiest items.
Very interested in this, I have A CR-10S with the stock mainboard. Would this simply screw back in where the original came form? Many thanks
Yes, I am pretty sure the mini boards will replace the stock CR10 boards.
No minsize/maxsize from bed are needed?
That is all set but the min max bed size settings.
Quick note Chris on the TFT touch display if the Black cable is inserted on the wrong slot on the screen end it will give Heatbed Temp fluctuations, I did have it on the wrong slot and it happened on my Ender 3, swapped it to the correct position and it went way, awesome little board with many features.
Thanks for the tip!
amazing detail, helped a ton!
Glad it helped!
How do you fix tmc connection error on this board.
Is this the stock firmware? Anything change?
Is there a video for setting up the BLtouch on this board

Hi I am now in building a printer looks like Anycubic how do i put Endstops on it the most of the Endstopswitches have 3 Cable so it is not possible to stick it in the Mini E3 2.0 because there are just two connect pins please explain how its done keep your good work in futere
You could swap them with the regular microswitches, or you use another 5v source to power them. I am not sure if they will work without power.
hi Chris watched a lot of your videos and you inspired me to build my own printer with the e3v2 but i dont know which board to select in platformio could you help me please
Hey, sure, you can use a couple of the chip and it will work the same, I use this one. STM32F103RC_btt_USB
OK Chris, fan question, fans are, case fan, hot end fan and part fan- on my OEM Ender 3 board i have stripped wires that go on teh screw terminal beside the main board power and my other 2 clipped on the board. i follower your video to set the fan in the code (FAN1_PIN) with the set value of 50 like you.. but can I still do that with putting my wires back in the screw terminal ( which you didn't ) as you have another setup, or should I splice the board connector to go on the hotend fan and then constant the case fan to the constant power... ugh
So the fans got sorted?
Chris - Compiled build environment is INCORRECT in this video at 19:05 - You should be in the 'env:STM32F103RC_btt' environment-C as in Charlie, NOT env:STM32F103RE_btt - E as in Echo as you are in this video for the SKR Mini E3 V2.0.
Hey, they should compile the same. Only difference is memory and it appears you can use 512k on both.
@@ChrisRiley Awesome.. thanks man.. really like your videos.. !!! keep up the GREAT WORK!!! you ARE AWESOME!

My part cooling fan can't be controlled. What might the issue be?

If the board works well I'll buy the 35 touch display.
Do I have to change anything in the firmware?
I cannot use the BTT firmware because I have a Titan extruder and have to change the direction of rotation.
@@herr_rossi69 All you have to do is update the serials make the first one 2 and the second one -1.
I had trouble finding out if v2 supports closed loop stepper motors...
Even if they don't have the direct port you can use an adapter, and it should just be a setting in marlin. But we will wait for the professional to answer :-) lol
Yes, you should be able to make it work one way or another.
I have a problem with the connection of skr E3 mini v2.0 and cura. Connecting to a computer freezes the printer. Only connecting to another program allows you to control the ender as a repiter host.
Interesting, maybe there is a plugin for Cura for a STM serial?
Installed my v2 using this video, thank you.

Thank you for your assistance.

Thank you! Yes, that should work just fine. I am thinking about changing mine to a 1.4 board.
Question...i have followed this video 10 times. reloaded new version of Marlin from the Github site. I have 2 problems. 1 When I reboot with the new firmware I get an error the error " failed to enable bed leveling" From what I have read, that is because there is no data. So the second problem. Homing, Everything seems to work when going to home, X & Y go home, the extruder goes to the middle of the bed, but the Z will not go down. it moves upwards, then stops. the BLTouch does it quick reset, probe extends and then I get an error "STOP called because of BLTouch error, Restart with M999" Any help from your user or you would greatly be appreciated. Thanks in advance...CO
My guess is that it thinks the Z is always triggered. Check it with m119. Check you white and black wires are on the S and G pins. Try switching these marlin settings.
#define Z_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop.
#define Z_MIN_PROBE_ENDSTOP_INVERTING false // Set to true to invert the logic of the probe.
so this has 2 z plugs, but only one tmc chip between them? so not a great upgrade from a 1.2, but with a splitter cable - i'm assuming you cant control them independantly?
The are connected in parallel on this board. You cannot control them separately.
@@ChrisRiley cheers Chris.
Hey Chris, What is the solution for Nozzel Heat overshoot.
for example, I set temp to 200 it will go up and pass 230 then start going down again.
I tried to do the PID tuning But failed due to the problem I mentioned above, can you please help with this matter.
using BTT SKR Mini E3 V2.0 I check all the wiring and for sure has nothing to do with that.
totally new to this and thanks to you I'm learning so much. appreciate your help.
So PID is really all you can do here. Silicon socks can help as well. Try to set you PID auto tune to 210 and reset those numbers in eeprom. Preheat to 210 also before you start the autotune. I would check your PSU voltage too, make sure it's not too high.

@@ChrisRiley Thank you for the reply and yea the board was defective. No doubt in my mind that this is Canada poste fault. It took me 4 weeks to get my board
Can I use Bigtreetech skr mini E3 V2 in the 3D printer I made myself?
Sure you can, there are lots of firmware example out there to help you configure it.
Chris, this works great for me, but how can I export the firmware file to the server card, tried a direct connection but VNC studio rejects it, how do I export the firmware file so I can upload it via sd card?
On the STM32 there is no way to do it from the serial I am afraid, you have to hand truck it with the SD card. The STM chip takes some sort of interpetur to flash it.
what are those crimps used on the end of your power cables?

Would it be beneficial to go dual z with this board on an Ender 3? Possibly make a guide on it since it looks like a simple upgrade to do with this board?
There would be some benefit to it, but maybe not worth the money. The X axis is short enough it's not as much of a problem.
I don't see the point on why you did all that procedure for the fan (swapping the connections, swapping the pins in Marlin etc.). I mean: you're still going to have only one Marlin-controlled fan and the other one full-blown. Thus, the overall noise won't be reduced. So, why u did that?
The hotend fan is now Marlin controlled, it only comes on when printing.
@@ChrisRiley Ok, now I see the point! Thus, I followed your guide and I have inverted the two fan connections on the controller board. Now the hotend fan is Marlin controlled while the controller fan is always on at full speed. But I replaced the latter with a very quiet 40x40x20mm Noctua fan and since I'm sharing the rear case with a Raspberry, I think it's ok to have the fan always on (perhaps I could GPIO contol the fan from the Pi?). Not a life changer while printing, but much more comfortable while idling at least. Tnx allot for your suggestion! :)
i got my board and the lcd output is keyed torwards the outside instead of the inside like in the video. the lcd wont turn on either. im so new to switching parts that i cant tell if i did something wrong or if my board is bad
It's very common to have to flip that plug over to get it to work. You can probably just slide the LCD plastic shroud off and turn it 180.
I tried that and the screen works like its supposed to now. Thanks for the help!
Hello Chris, i have a question. I've installed this board on a CR10-Mini. It was running an SKR 1.4 Turbo before (temporarily since i didn't want to cut up the control box for SD and USB), and it was fine, nothing weird going on.
However i had a bunch of issues with the Mini E3. The steppers were receiving the wrong commands. For example X was behaving like Z both in terms of Hybrid Threshold and steps/mm, Z was behaving like either X or Y (couldn't quite tell) and Y seemed to behave like the extruder and got hot AF, even though they were all wired correctly. I didn't want to start from the Ender 3 config and change it for my machine, rather i started from the stock Creality config and changed it for this board. After a day of troubleshooting i found some settings in Marlin that would allow me to get them running proprely (X_SLAVE_ADDRESS 0, Y_SLAVE_ADDRESS 2, Z_SLAVE_ADDRESS 1, E0_SLAVE_ADDRESS 3) and the "best part" is i couldn't find anything regarding the issue on the internet.
I still have one nagging issue though. My part cooling fans (i have 2 5015 in parallel and a Noctua 40x20 for the hotend heatsink on a Hero Me Gen5) are buzzing. Sounds like PWM noise, but it's really annoying and loud. Sounds almost like a small speaker. They seem to only buzz below 75%, or maybe it's just the fan noise that masks it at 75% and above, but it didn't seem like it, i tried listening carefully. I don't know about the heatsink fan since i always run that at 100% and it's basically dead silent.
I had tried enabling FAST_PWM_FAN in Marlin (Configuration.h) since the description seemed to suggest i might fix my issue, however it doesn't seem to be supported for that chip yet.
My question is, do you think this is a "bug" with the board, maybe related to the fact it's running 12v and not 24v (even though it can run in both and they also state it supports the CR10 Mini and original CR10 which are both 12v) or a config issue or a hardware issue on my side (fans or wiring) ? Have you installed it alongside a 12v PSU or encountered this issue with any of your machines ? Curious if maybe you know of a solution for this. Needless to say, neither of these issues presented themselves on the SKR 1.4 Turbo...
I think it might be a bug on the board, I haven't tried these on 12v yet, but I can almost guess that it has something to do with the new regulator on the board they are using. Not sure what the fix would be.
I've had the exact same issues... I just fixed the steppers by comparing the configuration_adv.h with the official marlin branch with the broken one from BTT (the current BTT branch doesn't compile) and from there change stuff to copy the BTT branch.
As for the PWM noise. I feel like it's hardware related and seeing that the only major change from V1.2 is the 5V regulator it would seem like a logical source... I run on 12V but it really shouldn't make a difference from running on 24V, if anything the datasheet says the regulator is more efficient at 12V.
I think i'll check it out with an oscilloscope next friday and try to figure out were the noise is coming from.
@@crookedtooth6445 Thanks for the the update, I would be interested to see what you find.
@@crookedtooth6445 I'd also be very interested in your findings. I have long since fixed my steppers, infact they were already fixed when i had posted this. As for the fans, i used SOFT_PWM in Marlin and they're definetly quieter. No longer do i have the annoying electrical whining, however now i've got clicking noise when it pulses at low frequencies (i.e. when you're running the fan slowly)... Could probably tune it by messing with the scale, but it eats into the range of PWM that you can use from what i understood. Anyway, haven't touched the printer in a week or so since i've been very busy with work and other things as of late.
Hello, not sure if you’ll see this but would this help me in resurrecting a printrbot simple metal?.
Yes, this would be fine for that printer. It might not fit in the case though.
Ha! Thank you so much. Will take a stab at it tonight and see if I can manage to creat a firmware file that works. Been stumped for months.
Hi Chris i was just wonder is there any way to link a tablet directly to and skr board and use it to control and upload gcodes direct
Not that I know of, I am not really sure how the serial would work on a tablet.
So if i get this thing I wont have to Flashboot? Is that the case?
You do not have to flash a boot loader if that is what you mean.
cant find the project tasks in platform io.... nor stm32F103. i have the latest version
You might have the wrong folder added. Make sure you add the folder that contains the Marlin folder.
Any help? My platformIO has been loading tasks for like 2 hours lol
Mine does that on occasion, not sure what it's waiting on. I usually close and reopen to get it going.
Chris, would this board mount well in the Ender 5, would sd cards line up with the case. I currently have the V1.1.4 board in it?
It's designed to line up with the ender 3 case, but I am guessing the ender 5 is the same. Check the github drawing. github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/hardware/BTT%20SKR%20MINI%20E3%20V3.0.1/Hardware
@@ChrisRiley Thanks, for your answer and the link. Good video.
Would you now why on the most recent software revision on the skr v2 it's not giving me an option to release the sd card is there a way to ad that in the firmware?
Release you SD card? Not sure what you mean.
@@ChrisRiley before I updated It would give me the option at the bottom of the tft35 to release and re insert the SD card from the main board the update changes it to change hardware but it won't do anything unless I change over to touch screen mode and then it will let me release the SD so it doesn't get corrupt il try and make a video luckily I never deleted the pre-configured file and just added (.Bin) to the end of it and re flashed
@@J.L.M9714 Oh, I have never seen that feature before to release it, I didn't know that existed.
@@ChrisRiley lol IL try and make a video thanks so much for your response I appreciate it great videos as well

I have all my settings set how I’d like in my firmware for the V1.2 board. However I decided to buy the V2.0. Can I just throw my old firmware for the V1.2? or do I need to do it all over again with the version of marlin that preconfigured for the skr mini e3 v2.0?
Also I don’t want to use my z stop. I took it off and i don’t know where it went. I want to use my bl touch as z min end stop. How would I hook up the bl Touch on the board?
So just use the same firmware but update the board name to 2_0. Bltouch, just leave the red,orange,brown wires on the probe pins and move the black and white wire to the Z min endstop. Make sure white is on S and black is on G.
how can u use 2 part cooler fan?
You can just wire them together the pins should be able to handle it.
i would be very happy if you had a video about pwm signal controlled motors
THAAANKK YOUUUU
You're welcome!
I am working an making an infinity printer with this board. For convince I'm trying to switch the Y-Stepper port with the Z-Stepper ports in the v2 marlin firmware so I can utilize the 2 ports the Z has. I can't find any way to switch them, so I was wondering if you know if this is possible or not? Thanks!
Yes, just switch them in the Pins file. "pins_BTT_SKR_MINI_E3_common.h"
#define Y_ENABLE_PIN PB11
#define Y_STEP_PIN PB10
#define Y_DIR_PIN PB2
#define Z_ENABLE_PIN PB1
#define Z_STEP_PIN PB0
#define Z_DIR_PIN PC5
my boards has the 2.0 bugfix. should i upgrade it to 2.0.9?
I would, yes.
@@ChrisRiley Okay, Thanks!
