It turns out that I have V2 instructions but my BL Touch is a V3.1. I still need help
@@markpicklesimer75 Hi. I can try to help out. What issues are you having?
@@3DPrintscape I installed a real touch that had all five wires in one ribbon. I was installing it into an SKR mini v2. I had planned on using the street five pen but all of the wires were in the wrong color order. What I ended up doing was stealing the JTL connector off of my Stock Z stop, Took the black and white wires out of the street five wire ribbon. Then I rewired the blue yellow and red to match the description in your video. Then I had to re-wire the five wires coming out of the BL Touch unit itself. I had it all working out with someone else’s firmware video and then I decided to make extra changes that you had in your firmware video and now it is not working. I’m not sure what changes were made that made the system not work any longer.
@@markpicklesimer75Try to comment out #define BLTOUCH_DELAY 500 and #define BLTOUCH_FORCE_SW_MODE in the configuration_adv.h file. I know these setting have cause problems with some of the bltouch clones/off-brands.
@@3DPrintscape I will try this when I get home from work. I’m not sure if this is the fix because I have a real touch brand
Great video! Followed every step and got my BLtouch to finally work. Especially loved that it focused on the SKR board. Many other youtube videos cover the generic V4.2.2 board that comes with the Ender 3.
Hi. Thanks for the feedback and im glad you got the bltouch working.
the best guide on UA-cam ,no one talks about the right wiring color ,i had to switch red and blue , thnx for sharing
You're welcome!
You saved my printer. Was about to launch it off a bridge. Followed you tutorial carefully and now I'm printing with great results. Thank you
Glad I could help :)
Great video! One little tip for ya...instead of having to add G29 to your gcodes, you could always uncomment ENABLE_LEVELING_AFTER_G28. This way it's always going to use your ABL mesh. I personally like to hard code all my standard settings (including my calibrated esteps number) that way I don't have to mess with it later. Another fun thing to add so you don't have to manually mess with it later is changing the preheating presets. (line 1702). I don't print ABS, so I replaced it with PETG and set my standard nozzle and bed temps for each.
Hi. Thanks for the feedback and tips. I didn’t think of changing that in the firmware but ya it would work.
A Great tip Andrew! I will be installing an SKR Mini E3 V2.0 as soon as it is delivered as I recently went through the pain of installing a BL Touch Kit from Creality with 1.1.6 BL Touch firmware and it is terrible firmware, the x,y offsets were not changed so when probing the nozzle was in the position where the probe should have been, and also when slicing a part in the centre of the bed it ends up printing far right on the bed, also they did not implement baby-stepping so you had to restart a calibration print for each change of the z offset which decided to stop working altogether after a while, and I am not 100% convinced the firmware is actually using the mesh created by the BL Touch, Creality did not answer any of my questions and I contacted them in 8 different ways, I bought the kit thinking it would save me time from editing firmware, I think I have learned the hard way about Creality's programming skills, which isn't really programming but the config editing and they cant get that right for their own printer!
Holy crap man!!!! I have looked everywhere for a video that explains and showed exactly what you did!!! Thank you so much!! I have had the bl touch for 6 months, hooked up for 3 and never plugged it in because I had no idea what I was doing. I have watched hours of UA-cam trying to figure it out and googling everything and couldn’t find anything that explained it better. No one explained the wires switched, and mine were and I was so confused. I’m new at printing so I got the already done one you showed, I just picked one and hoped it was right, but your video confirmed it was the right one. Thank you so much.
Hi. Thanks for the feedback and the lack of content around alot of 3d printing is one of the reasons i started this channel. Im glad you were able to get everything running.
Great guide! Covers all I needed to know to troubleshoot what other guides failed to cover. Thanks a lot!
You're welcome!
This video saved my Ender! I've been convinced for the last year that ABL is worthless and the BLTouch is junk. Turns out my firmware just wasn't using the mesh, or something, and was severely outdated. I didn't have the probe wizard, or babystepping that could save into the offset on the fly, or a ton of other quality of life improvements. Now my first layer is going down perfectly even and the interface is easier than ever to use. Thank you so much!
You're welcome, im glad i could help :).
Hey thanks! Tried for a long time, your firmware edits made it work. Thaaaank youuuuuuu!
Glad I could help :).
I'm considering a BTT board upgrade for my new Ender 3 Pro, and just wanted to say thank you very much for covering the layout and firmware modification for a 5-pin probe setup versus the 3-pin and 2-pin split setup, even though you were using the latter. Can't wait to silence these motors!
Hi. Thanks for the feedback. If your going from an 8-bit, or the 4.2.2, board, you will love the BTT one.
Thanks for the video and your firmware video. There's no way I'd have worked through the issues with my SKR Mini and BLTouch without them.
You're welcome!
I tried 5 different firmwares to get the BL touch to work on the BTT E3 V2, none worked. Most other compiling videos make assumptions on computer knowledge, which resulted in failed results. This video was to the point and not a watch builder video.(Definition: "Watch builder" You ask someone what time it is and they tell you how to build a watch). Thank You!
Hi. Thanks for the feedback, im glad i was able to help out :).
Thank You Thank You Thank You I had spent days trying to get it to run. With your video it was running in 2 hrs
Glad I could help
DUDE! You saved my ass with wiring... had red and blue reversed!!! Thanks!
Hi. Cool, glad you got it working.
well its a good thing I watched this before just plugging my signal wires in, I had the blue and red swapped like you said so you saved me some smoking cables!
Hi. Glad you caught it before hand :)
Best comment for 3Days searching .. thumbs up. Only this could help for get the BL Touch running correctly on the skr mini e3 v3
Hi. Thanks for teh feedback, im glad i was able to help.
Much appreciated
Hi. Thanks for the feedback :)
I love you men. I have try for 2 days and thanks your videos I have succeeded ! 😁
Im glad i could help :).
Thanks a lot for this video! I was having issues with my BTT SKR MINI E3 V3.0 and Creality CR-Touch on my Ender 3 but your video was very helpful, and my printer runs flawlessly now.
You're welcome!
you are the real MVP
thanks!
You're Welcome
Great video explains bltouch very straightforward thanks
No problem 👍
Thank you for putting this video together. It is very appreciated. It would be immensely helpful if you could: 1) improve the screen capture quality -- on my hi-res screen It is blurry and near impossible to distinguish the text. 2) could you speak out the name of the parameter you are modifying rather than using terms like "uncomment this". Again thank you for the effort you put into this video and for sharing your knowledge.
Hi. Thanks for the feedback, i will work on those going forward. The screen capture resolution has been tricky due to different sizes. I ended up settling on 1080p captures for now.
every time I go to compile this I get an error. "include errors detected. Please update your includePath. Squiggles are disabled for this translation unit"
Hi. It sounds like the firmware folder may need to be moved closer to the root of the drive you are working on. The folder structure of the firmware goes pretty deep and Windows doesnt like long paths/file names. I typically create a folder called firmware right off my c drive and put the firmware there.
that was wonderful so many videos but non as good and clear as this
Glad you liked it
This got me exactly where I needed to go, Thanks!
You’re welcome
This was very helpful. Thank you!
You're Welcome!
The Failed to enable bed leveling error can be resolved by starting a bed leveling mesh after doing you z offset.
This was a great video thank you for all the help.
Hi. Ya that’s how you get rid of that message and you’re welcome.
Thank you for this, i have this exact setup on the way soon .
Glad I could help
Robert this video is great I have 2 ender 3 pro'2 and 1 has this exact board in it so this video helped me get my bl touch installed perfectly. I am running the factory firmware on it but would love to build a version like you did in the video. I wish I could get a copy of the one you built on here, as my printer is the exact same. I am just not quite comfortable enough to write my own firmware yet LOL. I was able to obtain a full version of marlin for my other printer which has the stock 4.2.2 board and it runs so much better than the creality firmware. Just wanted to say again great video it helped me very much.
Hi. Thanks for the feedback. I actually have build available here that you can use. 3dprintscape.com/marlin-firmware-builds/
Great guide, extremely helpful but once I click build it says - Unknown environment names 'STM32F103RC_btt_512K'. I'm using a CR-Touch but should follow the same steps right? Help will be much appreciated
Hi. Remove the _512k. There was a recent update to the bug fix line that removed that from the options.
@@3DPrintscape Thanks, ended up trying that and successfully compiled the firmware but now it says 'no printer attached', any idea what the problem could be?
@@adnaandavis4529 I would expect it to say that for about 20 seconds, then it should attach. If that's not happening, I would check your wiring.
I was with you up until ~5:30. Not sure how you got from installing the hardware to measuring the distance the probe is from the bed. I'm assuming you powered on and went it went to the home position? What firmware do you have installed at this point and how did you do that? I think I have the wrong firmware installed because mine isn't moving when powered on.
Hi. Once the hardware is installed, you need to flash the firmware then set the z offset, i think your on the last part right now. Im using a custom build of marlin, but the process is the same with the creality firmware. Do you see bltouch or anything in the printer menus?
Great work!
Thanks!
So I downloaded the BigTree Firmware and its STM32F103RC_btt_maple, do i still need to change it to 512K
Hi. I havent grabbed the latest build in a while so im not sure if the recent changes from the bug fix line were merged to it. If they were not, you will need to add the _512k, if they were you will get an error if you add it and try to compile.
I'm having issues with the bltouch probing off the bed on the y-axis during bed leveling. The initial probe (homing probe) is perfectly in the middle. The second probe (front left) then tracks to miss the bed. I also have my offsets set correctly (given offsets for my Hero me 5). So far to get printing i've had to change the probe offset for the y-axis to be technically incorrect. The home probe is not centered, but the rest work...Any ideas?
Hi. First make sure you cleared your eeprom. If thats done and you are still having the issue you can adjust your #define X_MIN_POS & #define Y_MIN_POS values. I think im running -5 and -10 as i had a similar issue.
you could just put a paper underneath then crash the hotend and the bltouch into the build plate slowly to leave two marks on the paper then use a caliper to measure
Hi. That may work but i wouldn't do it that way. Its not worth the risk of damaging something.
thank you very much sir
Most welcome
Hi Robert, Thanks for all the great how-to videos. When I initially added the ABL gcode (G29 ; ABL) to the Cura profile for the Ender 3 Pro, everything functioned properly from OctoPrint until I adjusted the bed a week later. The Z Offset and ABL calibrations from this video was executed countless times with no success. After hours of playing with these settings, I notice the calibration functioned properly through the printer display screen but failed via OctoPrint. I removed the G29 code from the Cura profile and it is now working from OctoPrint. I don't believe the G29 code execution itself from OctoPrint is the issue. Is the G29 pulling stored parameter values from OctoPrint or the controller to calculate the new ABL parameters? My printer has the BTT SKR MINI E3 V3.0 Controller and TFT35-E3-V3.0.1-Touch-Screen-Display.. Is there any other area I need to be looking at?
Hi. Thats interesting, it has to be tied to how octoprint handles things. It bypasses a lot and wants things it own way. The g29 command runs the mesh and stores the peramitors. You need to save settings for them to persist through a power cycle. What happens if you just send the g29 command manually from octoprint?
Hello, thank you for making this video, it was very helpful. I’m stuck one a problem though. I was able to compile and flash my firmware onto my printer, but now when I go to auto home, the auto homing sequence doesn’t even touch the X or Y endstops (which would lead to some collisions later on if I tried to do anything else with the printer). But The Z sequence works with the BLTouch probe just fine. I flashed firmware from bigtreeTech to confirm it wasn’t a wiring issue, and the auto homing worked perfectly fine for X and Y with the bigtree firmware. However there were some problems with the Z home sequence that are more troublesome than they are worth. Anyways I’m assuming this is now just a coding issue. So now I’m trying to make my compiled firmware work. Do you have any suggestions to fix the x and y homing issue? Thanks.
Hi. Can you try one of the builds from my site? I want to try to narrow down what the problem could be.
I ended up restarting with the same btt code. I followed a step by step guide online for Ender v1s and it ended up working. Not sure what the issue was as I was watching several different videos (probably the root problem) on how to code the firmware, but it was definitely a coding/user issue
@@landon3105 Thanks for the update, glad you got it working.
Can you plz help me im trying to do this on my anycubic mega zero with the stock board would there be a way that you can get all the firmware ready and like share the done file so all I do is put it on my SD card ove been working on it for about 10 hours and its not working

This is more of a Viscose issue, I don't have that "check mark" on the bottom.
I've been struggling for about 4 days now to set this stuff up. Please help.
Hi. It sounds like Platform.io wasnt installed, VS Code wasnt restarted after the install, or the wrong firmware folder was opened. The folder should be the top level folder and have the platformio.ini file in it.
@@3DPrintscape You have to install C++ in VS. I had the same issue and that fixed it!
If you have the C++ and Platformio IDE extensions installed, check to make sure you have opened up the folder which contains the 'platformio.ini' file. The check mark won't show up unless this file is at the top of the folder file structure. You might not have the correct folder open because Windows "Extract All" will add another folder layer during the extraction process.
@@lynnkeith2289 Im glad to hear its fixed. platformio installs C++, but if something happened to that install I could see it causing the behavior you saw.
@@Christopher-nt6fg It definitely possible he had the wrong folder selected as well, but if C++ wasn't installed it would behave similarly.
Hey! Nice Video! But I have the problem, that when I use z-stop or the z-probe - z-stop my printer keeps moving down. You know a solution?
Hi. how is the bltouch wired?
When I follow your instructions on VS Code I don't have checkbox to build on my (latest) version there are 2 errors in the far bottom left though, any thoughts on this?
The 2 errors are to update include path
I fixed this, I had been in the Python environment prior to configuring this firmware and it loaded up the next time in python, I just switched to Platformio
Hi. Im glad you got it working, though the python environment shouldnt be needed. I don't have that running now and it works for me. My guess is that it installed/repaired another component.
@@3DPrintscape I was using python for something else prior to configuring the firmware and VS Code must have loaded in Python mode when I came to configuring Marlin, that's why I was getting errors and no checkbox
I can’t seem to find the babystepping feature. I was able to compile it fine at first, but had to recompile another .bin file for the offsets when my printer autohomes. Any tips? I’ve got what you toggled and even enabled the feature where it’s always available. No dice still.
Hi. Try to clear eeprom if you haven’t already. If you have maybe check in the menus for something that sounds similar in function, maybe they moved it.
THANK YOU SO MUCH
You're welcome!
hey im back haha, i was wondering if theres any way for you to reduce the amount of probes? IE instead of a 5x5 a 4x5/4x4 grid of the bed. Amazing guide btw!
Hi. Thanks for the feedback. If your using Marlin firmware, you can change #define GRID_MAX_POINTS_X to whatever multiplier you want. The default value is 3, which creates a 3x3 grid. If your using the prebuilt firmware, im not aware of a way to change the value.
Hello I have followed all the steps and loaded the firmware on sd card, my probe wont work its a 3d touch probe.
Hi. Are you seeing bltouch setting in the menu on the printer? Im trying to see if it actually took the firmware.
Hi I’m thinking of upgrading my board to a skr mini v2 did your ender 3 pro used to home with bltouch in center of bed without using z end stop switch? If so when downloading the firmware do I need the same version as you?
Hi. Yes the printer would home in the center of the board with the bltouch. I have my firmware available to download if you want to try it out. 3dprintscape.com/marlin-firmware-builds/
@@3DPrintscape thanks for replying to my comment that’s greatly appreciated I’m waiting for my v2.0 board to arrive once it does I’ll be upgrading I just wanted to be sure which firmware in need for the bltouch to home in center and not use the z axis end stop switch has I removed it when installing bltouch
@@Yngwiejmalmsteen08 You will want to use the z homing software. Either the one available from BTT github page or my site.
@@3DPrintscape thanks I received my board today I swapped out all the cables and changes the cables on the bltouch like you did after turning on printer I see it load marlin 2.0 on the skr board but after copying the z homing firmware onto sd card it doesn’t seem to sit at a blue screen just boots up with marlin on screen? I see people saying it needs to be flashed with sd card that come with it but I didn’t receive a sd card with my board
I have tried many sd cards and renamed the file to firmware.bin but still no success it refuses to load the firmware it seems and just boots as normal..somebody did suggest to add file called firmware and file called firmware.bin to the sd card could this be the problem
Shouldn't the Z offset be done with a pre-heated bed and nozzle? There is expansion of each after reaching temp and this will affect the gap, not insignificantly.
Hi. I tend to make the final adjustments with babystepping, which is done when everything is up to temp, but to answer your question. Yes, you should have the nozzle and bed heated up.
My BL Touch has the wiring harness with BLUE, RED,, YELLOW, BLACK, WHITE. Can I place this where the "BL Touch" goes according to your first selection/option goes? My BLUE wire is on the outside (first wire) then the RED and so on. Also, according to your video, where your BLUE, RED, and YELLOW wires are, would the next wires be BLACK then WHITE, or WHITE then BLACK?
Hi. The short answer is it depends. The problem is i have seen these shipped with too many different wiring colors. I would recommend mapping the color back to the pin and making sure its plugged into the right spot on the board.
I followed your video step for step. Once you made a change vsCODE I paused the video and made SAME changes. Ok. Mine compiled just fine. I got my ender 3 pro with Mini e3 v3. Well almost. The blTouch levels the center of the bed but when it’s starting a print and lays down that warmup line on left side of bed, we’ll the hot end is still 1/2” off the bed. The abl pin does not extend. And the assembly does not lower to print. I thought at first it was the gcode of the file I tried. So I tried a different gcode and same thing happened. Is there a firmware setting I could look at for this ??
Hi. It sounds like your z offset isnt set, or not set correctly.
Such a great guide, but i feel like im being a dumdum and doing something wrong.
Ive got the creality BLTouch, set it up in the way that has you using the 3 pins on the main port of the board (Swapping my pins in the connector around so they were blue/red/yellow, the blue/red were reversed initially), and then using the "z-stop" 2 pin location on the board.
I got the firmware for the z-homing, put it on an SD card- Turn the printer on, it clicks the BL-Touch sensor a few times, then bonks at me about not being able to enable bed leveling / invalid mesh.
When I look through my options, I see "MBL" instead of "ABL", and no options for the BLTouch. Seems like its not updating the firmware properly, but cant figure out why
Hi. It sounds like it may have not taken the firmware. Can you check to see what under the about/info screen?
@@3DPrintscape From the info screen my printer says:
"System: Marlin bugfix-2.0.x
board: Bigtreetech_gd_tft35
Firmware: v27.x"
Hopefully this is the right information. And thank you so much for your help by the way, i super appreciate it!
@@SidewaysGts I would try to flash the firmware again. You should see bltouch in the menu after doing it.
Thank you!
You're welcome!
Had an issue with my bl touch inconsistently deploying. Seems to have been fixed by re-terminating the red-blue-yellow cable with the proper connector. The longer connector is meant for different sized pins and was sitting very loosely on the onboard connection.
Hi. Thats an interesting one, thanks for sharing.
Hello, i can`t get the bltouch to run. Homing the z-axis doesn´t work-> stopped. With M119 i get the message z min: triggerd, shouldn`t it open? How can I fix this problem? Z_MIN_ENDSTOP_INVERTING false, changing to true doesn´t work, because marlin can´t compile it.
Thanks
Hi. My initial thought is that the sensor wires are reversed or the config doenst match how the bltocuh is wired. Z_MIN_ENDSTOP_INVERTING should be false if you are running a build from after June 2021.
Hello, this Firmware works for an Ender 3 with a BIGTREETECH SKR-Mini E3 V2.0 board... and TFT 35 E3 V3.0...? Congratulations for the video and thank you
Hi. Ya it should work fine with that combo assuming the tft firmware is up to date.
what exactly are you measuring on the y axis? nozzle tip to front of x gantry?
Hi. Its the distance from the nozzle to the probe on that axis.
so i always get stuck at compiling. the check mark to compile doesnt show up and it states i have errors in both file with a squigly line
why cant i compile i followed everything please help
Hi. What folder do you have open in vs code? The checkmark not showing up usually means platformio is not installed or the wrong folder is open.
Very informative and has helped, but I have an issue I haven't been able to resolve. I'm running the SKR mini e3 on a CR10S5 so had to also adjust bed size, but otherwise used your settings on BTT firmware for 1.2 using the probe/servo pins on a 3dtouch. When trying to level, the z doesn't stop when the probe shows it's triggered, which of course leads to an error of hitting the endstop. I have adjusted my z offset....is there another setting I need to look for? I would think from other videos once triggered the z should stop even if in the air? The LED does show it's triggered, but keeps going.
Hi. Thanks for the feedback. How is the bltouch wired? It sounds like you have it wired with all five pins going to the bltouch port but the firmware configured for z homing with the bltouch.
thank you
You're welcome
I attached bl touch like u did in video and download firmware bltouch z homing. Now z motor only can go up. Same thing if i try trough menu manualy lowering z axis.
Hi. Sounds like the wiring is wrong or the firmware doesn't match the wiring. How is it wired and what firmware are you using?
This video worked great.. except one problem. The TFT, by default (I have the BTT TFT35) when I try to enable it, it just fails to compile saying "LCD doesn't support bed leveling" I'm using the SKR Mini E3 V3, as you have here, so.. still working on this to get the BLTouch to trigger. It also seems to have removed a ton of options from my TFT (as in, I can't select type of load, like PLA/PLA+)
Hi. I will need to look into this one more when i work on the Marlin builds for the v3.
Just tried installing the SKR E3 V3 board, But the hot end (E0) will not heat. This i the second board with the same error. I there anything that I could have done to cause this.
Great Video
Hi. Can you verify its plugged into the correct ports and that the cable/heating element isnt damaged?
I’m a bit confused, if my wires came with the 5 pin, do I still need to change it for the 3 pin adapter? Also, with the 5 pin connector, do I still need to change wires around to prevent any possible problems?
Hi. No, use the 5 pin adapter and plug it into the bltouch port and leave the z-stop plugged in. Also, make sure the wiring is in the right order on the 5 pin adapter.
I followed all except downloaded the Marlin-bugfix-2.1.x. I do not see.pio file. all hidden files are shown too. can you please help? I also do not see Firmware.bin file anywhere
Hi. Try grabbing the stable release to see if everything is there.
i have tried to add the fireware.bin to my sd card and put it into the tft slot. The firmware doesn't load. Any advice? The firmware.bin file is in the root and i did manage to upgrade the tft firmware following your video tutorial. no sure what to do here now
Hi. Make sure the SD card is 8GB or less and formatted as FAT32.
It's a great guide! So helpful! Thanks for posting it.
After I have tried everything, there's still one thing that I can't fix, the bltouch only measures the bottom left corner for bed leveling and I can't get it to measure more points on the bed.
What can I do?
Thank you in advance!
Hi. Is it actually probing the bottom left corner or attempting to and failing? If it cant get a good read, it will just fail then move onto the print.
In the platformio the default_envs is mega2560 downloaded file 4/3/21.
Hi. If your downloading it from Marlin that doesnt surprise me. You will want to make sure you update it when you download a new copy or anytime your switching between boards.

Hi. So I keep getting this Error: Unknown environment names 'STM32F103RC_btt_512K, and I'm not sure what that means. Any ideas?
Hi. Remove the _512k, that was taken out of the bug fix line about 6 months ago.
Hi I need help I can't compile the program, I use default_envs = STM32F103RC_btt. but still failed to compile
Hi. What is the actual error your getting?
My "default_envs" is set to mega2560....do I need to set it to the "STM32F103RC_btt_512K" I have the same setup as your video.
Hi. If you using a build after June, you will want to change that to STM32F103RC_btt. The _512k has been removed as an option.
Hello,
I'm getting M999 error when I have my BL Touch installed. Do I need to do any rewiring? I have a V2 BL Touch with all five wires in one ribbon. What order should the wires be in? The ribbon comes with them in (from top to bottom) Blue, Red, Yellow, Black, White.
Hi. The wire order you mentioned is correct, so if its in that order its good. Did you make any other changes to the printer and can you provide more info on your setup.
maybe I am crazy or just dumb, but I dont have a check box when trying to use the btt version for the skr e3 turbo.
Hi. The checkbox is only there if platformio is installed and the firmware folder that has the platformio.ini file is opened. If verified both of those, try to reinstall the c/c++ plugin.
Just got my SKR Mini E3 V3.0 and jeez, this is going to be a p.i.t.a. to set up properly lol! I referenced this video to follow similar steps, but it's so new that there aren't any stable firmwares apparently. You plan on upgrading?
Hi. I've considered picking up the v3 but to your point, there isn't much reference material on it. Id does look like the BTT github page has the config that can be used a starting point though. This may help out for your marlin build. github.com/bigtreetech/Marlin/tree/SKR-mini-E3-V3.0-G0B1
@@3DPrintscape thanks for sharing! I was pondering the thought of creating a little vlog on getting this thing working, but I'm at the "trial and error" point where I don't want to make a video of 12 diff tries before having success, haha! I'll tag you if I get this video up today.
@@JDMsohc Sounds good, if you run into issue let me know and I will try to help out.
@@3DPrintscape first issue has arisen, lol! After I used WinMerg to compare my old Marlin to the new one I just downloaded, I get pretty far through compiling the firmware in VSC, but then I get this error.
: fatal error: variant_MARLIN_STM32G0B1RE.h: No such file or directory
I've tried to search for this error but nothing pops up, as I assumed nothing would given that this is so new. Any tips?
Thanks!
@@JDMsohc That may just be a file length issue. Try to move the firmware folder closer to the root of your drive.
The _512k was omitted because some of the earlier versions (V1.2) used ARM processors with 256k memory, they likely forgot to update it when copying it over for the V2.0 with the larger flash
Hi. Thanks for the info. I figured it was a change meant for the older boards that didnt get corrected for the newer ones that support it. I just know its caused a lot of issues for people.
Hey, do you know why wherever from I download a marlin, I dont have .pio folder ? I dont know what to do. If this helps i have windows 11 and i see other dot files like .github Please help :(
Hi. The .pio folder should get created when you build the firmware, its not there by default.
My firmware compiled successfully without adding the “_512k” at the end of the default_envs line. Will this cause any issues when flashing to the printer? Or was this not a problem anymore?
Hi. The _512k is no longer needed. There was a release made to the bugfix line over the summer that removed it. If your build was successful, you should be good.
I just can't manage my printer to work with this and also tec support from BTT is really bad
Hi. What issues are you having.
i need help on how to update things on my printer.... where do i go on my printer screen????
Hi. If the firmware is on the sd card it will automatically pull it in when the printer is powered on.
I’m having trouble with the platform io tab in vs Code and it will not let it complete the build it will fail it
Hi. What error are you getting? It should be in the console output.
So on mine I wired it the same way you did and my Z stop DOES NOT work I cant figure out why but everything I try the Z axis doesnt stop and keeps hitting the bed until I power it off, any suggestions??
Hi. I think you reached out on discord and the issue was related to the firmware. If not let me know.
I followed step by step and I'm missing the babystepping option from the tune menu. Double clicking brings me to z offset but I cant adjust anything while printing. Any ideas?
Thanks!!
Hi. Try to clear your eeprom.
Do you need to change the bl touch wiring on the v3 board?
Hi. If you leave the z stop connected and the bltouch connected to the bltouch port you shouldn’t. That is assuming you have one with the 5pin adapter.
yeah for the final step i dont know if im dumb or if it updated, but how do i kick off the build, there is no checkmark for me
Hi. The checkmark not being there is typically caused by the platformio/c++ plugin not being installed (or the install was bad) or the wrong folder is opened in workspace.
i tried doing everything in this vid just with my anycubic files instead and i had 130 issues
Hi. Sorry to hear you are having issues. What errors are you having? Also, you can reach out on Discord for assistance as well. discord.gg/Bu94EYVkrU
I have a issue, the probes are working fine but when you start to print it is as if the printer forgot the layout of the bed. the z axis wont move to adjust for the bed being uneven, any idea on how to fix this?
Hi. How is the bltouch wired and what firmware are you using?
@@3DPrintscape the firmware used in the guide, and the bltouch itself is working completely fine. The problem is exactly like in this video ua-cam.com/video/tJHzKikWswg/v-deo.html. My caveman brain just doesnt know what hes doing to fix it lol
@@mingo7687 I cover BTT and marlin firmware in the guide, so i would need to know what one/version you are using and how the bltouch is wired.
@@3DPrintscape sorry about that, but im using marlin and its wired to the bltouch port
@@mingo7687 Can you try one of the firmware builds from my site? I know they are working, so that will give us a starting point.
@3D Printscape Hello. I am trying to install my BL touch that I got straight from Creality, but It is designed for the original board... I cant rearrange the wires on the connecter. Can you please help?
Hi. Ive seen the bltouch shipped with 5 wiring variances at this point. I wouldnt count on getting the right one anymore as there is no way to guarantee what your getting. If the one you have doesnt match what is needed, you will need to change the pinout.
I've been having issues with setting up the firmware. for some reason every #define line is an error. i saw that was the case in the video to, but then they just dissapeared at 11:47. I tried following the axact steps, including commenting the s stop out and back in, but nothing changed like it does in the video. these errors also mean i can't compile the firmware.
Hi. Can you provide the full error you are getting?
I do everything right but I can't build it I just got an error why !!!
Hi. What error are you getting?

@@ix7amdon174 did you fix it? I have the same problem
Your bltouch for z homing is the only firmware I could get working, btt firmware I could not get working not a lot of support from anyone with clear directions…. With this board being out for as long as it has been there should be correctly working firmware
Hi. Im glad you were able to get it working with my firmware and i created the resources to help people out because of the lack of information available.
@@3DPrintscape also thanks for your service I appreciate it.... ended up watching most of your videos and compile my own....just watched the raspberry pi touchscreen vid... again thanks alot for the content
Noticed your comments about the ABL Mesh error after updating the TFT firmware. However, when I do the mesh leveling it only appears to attempt to do it at the bottom front left and doesn't move across the board. to the other points, as I would expect. What am I doing wrong?
Hi. Is the probe getting triggered at the bottom left? If there is a error in the reading, it will just stop there.
@@3DPrintscape I will check, also need to make sure I have installed it correctly.
Progress :-)
1. Installed the BL touch unit and wired it so that the original Z-switch stays in place
2. Installed the required firmware for using the BLT touch from the Bigtreetech Github
4. Restarted the Printer
5. Ran the ABL bed leveling which seem to work this time. Although I have a Y-Axis belt tightner adaptor, which confused things when the bed went to take the top measurement, the bed moved too far forward and grumbled (there must be a setting I can change to change the travel distance, if so please advise) , it was ok after that point and I saved the settings.
The only thing I could not do was set the P-Offset (I think it's shown as Z-offset on your video). I know if I used the firmware which does not require the original z-end stop switch, the function worked to a point. If I use it as it now, it homes the printer. Raises the head 10mm and then should go to the center of the bed, but on mine, it tries to move the head to the left while its in the home position. and I have to turn the printer off as the motor/belt for X-Axis start making a hell of a noise.
Any ideas why?
@@abtrooper82 What firmware did you end up using?
@@3DPrintscape All I installed was the "firmware-bltouch.bin" file, should I have installed the file "firmware.bin" to replace the factory stock firmware first? and then apply the "firmware-bltouch.bin" after or is the "firmware-bltouch.bin" the newest firmware for the board including the BLtouch function. The notes on the bigtreetech github seem to imply the firmware.bin file for the ender 3 does not support BLT, hence why I used the firmware-bltouch.bin" file. Sorry for all the questions
UPDATE : I think I know why - I left the original Z-endstop switch connected to the board, so I'm guessing this will confuse the printer and it's going to assume that the home position for the z-offset is now at the bottom left of the board and not the centre of the board, Correct? Should have paid closer attention to you video if this is the case :-)
@@abtrooper82 The firmware should have been named firmware.bin, I don't think the skr will pick up the firmware if its named something else. Also, the z stop should still be connected in most cases.
At the end of my firmware build, I received this message..."There are the new updates for platforms (ststm32)
Please update them via `platformio platform update` command."
Should I update and do the process over again?
Hi. Updating platformio won’t help with the issue you are seeing.
is there anything special we need to set up with the gcode or is it good as is?
Hi. You will want to add a G29 command to the printer profile in cura. I cover that in more detail in the update printer profile section in this article 3dprintscape.com/guide-to-install-a-bltouch-on-a-creality-32-bit-mainboard/ . Im working on the written instructions for this video, I just haven't finished it yet.
For those of you having compile issues with your default env, in 2022 + try using (STM32F103RE_btt_maple) this usually fixes any compile issues.
Hi. Thanks for sharing. Its also worth checking out the marlin auto build plugin, it helps alot.
So it gives a compiling error with the _512K but works without it should I just use the firmware compiled without the _512K
Hi. Yes build it without the _512k if you can. They made some changes in the latest bug fix release that causes issues with the _512k environment.
Hi! Can you please help me. My bed keeps hitting the nozzle on autobed leveling!! I have ender 5 with skr mini v1.2 and bltouch. I can't find any relevant tutorials for this exact problem 😭 thank you!!
Hi. It sounds like it could be a firmware or wiring issue. Can you join me on discord, it will be easier to help with troubleshooting there. discord.gg/Bu94EYVkrU
a bunch of red text pops up when i hit the check mark after im done defining everything i need
Hi. I would need to know what the error is to help. It should be the first red text in the terminal output.
