Amazing video!
I have a 24V powered Ender 3 with an MKS Gen L board. All 12V fans except the blower part cooling fan.
I'm going to set the D7 pin as my E0_AUTO_FAN_PIN
as I don't have a second extruder and thus this output is unused.
I'll be controlling my extruder fan along with other 2 case fans. These three 12V fans are currently powered from a Buck converter so I'll have to power this converter from the Extruder1 port (D7).
My drivers won't be cooled down when the hotend temperature is below 50º but I don't think that would be an issue, as I won't be moving my motors too much with a cold machine!
Hi Edward. Im finally getting roud to putting my printer back together. Currently busy with the fans. Im assuming according the the video that D9 is the PWM part cooling fan port. for the hot end fan. you are mentioning putting it into the HB port. what if i have a HB connected there? where would i connect the fans then?
Very good tutorials, sir. I am very grateful for your sharing of your knowledge to educate us.
You're welcome.
Hi Edward. You didn't show what happens when the hotend reches a preconfigured temp.
I run the extruderfan of the 12v main powersupply.
I want the fan running of the 2nd fan connector and only on at about 50 degrees c.
Great videos! Very informative no bullshit. Love them.
Thank you.
Perso j'ai la configuration "EFB" et j'ai modifié le firmware pour:
-Bed en D8
-Hot-End en D10
-Fan en D7
-Fan1 en D9
Edward: Your instructional style is terrific - I can follow along very easily. I was able to get a 24v fan operating using the M 106 command. However, you mentioned that it is possible to program it to turn on automatically instead of typing it into the command line in Pronterface. Have you done a tutorial on that?
You can do both in Pronterface and Slic3r. I'm planning on doing them soon, but Slic3r might prompt many questions.
Edward Braiman Great! Thanks
Excellent video! Thank you so much! Is it possible to configure the D7 as a fan?
Anything is possible.
@@EdwardBraiman :) thank you so much for your answer! I am a beginner, could you tell me where I should change the firmware to turn D7 into a fan port? Do you have any videos about this topic? By the way, your videos are helping me a lot!
There's normally a playlist in description to other videos on board.
I have mix hotend , It require only 1port for hotend ,Can I use 2nd Hotend port for My Mainboard cooling fan?
Yes
Hi, Edward! Might I assume that all of the screw terminals are at the same voltage? I'm trying to install a 24v hot end fan to a Robin Nano 2.0. Since my hotbed is already occupied, id like to put it on the HE1 terminals.
You're correct as long as your PSU is 24v.
You simply plug in the cable into your PC and edit the files - how?
I have the CH341SER drivers, pronterface even recognizes the COM, but it does not show up in device manager. Can't edit the software files. I'm stuck.
Ah, I get it now. It is not supposed to be like a USB stick with a directory opening? Thank you for your videos, I think I get it now.
You're welcome.
My board which I bought assembled has
Fan, Fan, Extruder, Heatbed.
Depends on the printer type you are using. I need more details to answer.
Possibly a silly question, but if you're using the bed control to control the fan, what are you using to control the bed?
You do not need to use a heatbed.
@@EdwardBraiman Most people think they get better results through using one though. But that does answer my question. Thank you.
You're welcome.
you need to do a single video from being to end on wiring and marlin of the mks gen l board. because i have 3 fans(parts, active and control box), hotend, bed heater, and ABL. and also in this video where are you to wire the the bed too
There might be a a video on more fans this week. As for a long video, would love to, but I upload from a coffee shop so it might take hours. Been waiting for Greenlight fiber optic internet for over two years, they have it accross the street. So when they install it the videos will get much longer.
Hi Edward.
So am I understanding it right: will there be a Video which descibes following?
I have 1 Hotend, 1 Hotbed, 1 Hotend Fan (-> Connected to permanent 12V left Side of X-Stepper Motor), 1 Part Fan (-> connected to „Fan“ Port)
So far so good.
But I have a Fan for cooling the Board itself, too.
So I‘d like to use the E1 (D7) Output with permanent 12V (Printer on = cooling Fan for the Board on)
I Know E1 is to be used as 2nd Fan if I only have 1 Hotend. I can start the Fan via Display -> Fan 2 -> 255. But in this case I Need to Start it manually everytime or I Need to put it in the Start skript.
But I would like to Set E1 (D7) via Marlin to permanent 12V so that the Fan is everytime on.
Thanks
Best Regards
So you have a bunch of fans you wish to run with different requirements. You can start some in the Marlin firmware automatically and other using Slic3r in expert mode select printer settings, custom G-codes and enter what action gcode you wish to occur at start of print and end of print.
what would be the result if you crimped two 12v DC fans together and plugged them both into the designated fan input?
It worked for me about a year. Just monitor it and it should be fine.
did it give out after a year?
The fan was fine, I broke the fan holder by accident. One fan worked even better after that.
Two 12v Fans connected together will have no bad consequences. Two 12v Fans connected in Series, Will each share 6v and the current will be same for both. If connected in parallel, they would share 12v drop but the current will be split.
If you plan on using two (or more) 12v fans to run on 24v, I would not suggest this. Horrible things would happen if one fans fails. Then, all 24v will be on one 12v fan. I use a DC-DC Buck converter (step-down converter) 24v to 12v and run multiple 12v Fans in Series and Parallel. Been over 1 Year, with no problems.
The downside is that both fans will work at the same input speeds. I have 1 blower fan cooling the part and one cooling the heat sink. I want the heatsink fan to run all the time and the blower fan to turn on/off or have a different speed from the heatsink fan. If you are using two blower fans to cool the part pointing at the nozzle then wiring them together would be OK. I am not sure why the gen L board did not supply a second Fan input/pin.
Ed, I have a question why did you select in the Marlin firmware the RAMPS board type and not the Makerbase board type. Are these board types interchangeable? And was that the only way to get the second fan to operate?
Ramps is one of a dozen printer boards on my channel. Check out my other playlists.
Thank You for the replay. You mentioned in the video use motherboard type "BOARD_RAMPS_14_EFF". But you are using the MKS Gen L 1.0 board. Does this explain my question better? I can't get my second Heatsink cooling fan to operate.
In one of my playlists I talk about a fan extender. You can run it off servo pins.
Hi Edward, I've been following your videos for a while now... Maybe I've missed it, but in the upper left corner of the GEN L board there's a white connector labeled 12 volts. My question becomes, on an Ender 3, which uses a 24 volt power supply, is this connector still outputting 12 volts? If so, can this connector be used as the hot end fan (not part cooling) for cooling the hot end ?
It may depend on input voltage from the power supply. I'll check after work today.

Edward. Can I do this but use the E1 terminals instead of the hotbed? I want to run extruder (1), heated bed, and at least two fans.
Yes, it's in another video in this playlist.
On MKS Gen L you can run I think 3-4 signal controlled fans, this depends on if you're using hotend ports or servo pins to control fans. In my playlist I think there is a tutorial on fan controller module.
How could the fans be connected, in case of putting double extruder?
You can use a fan extender. Check in my playlist for the video.
Is it possible to connect the extruder and the extruder fan to the same D10 input?
Not a wise idea with extruder. Depending on board and Marlin firmware you can setup to activate during print at certain temperatures.
Watch my tutorials on fan extenders.
What is the other white connection next to the X axis stepper plug?
12v aux power port.
@@EdwardBraiman If I run a 24v system would that be 24v then?
@@stevealles3482 Yes, but you might want to verify before using for 24V and also which component connected to this port because all my examples are based on 12 volts for safety and to keep people from cooking parts they jest purchased.
@@EdwardBraiman Thanks I just verified and it is 12 volts. I am wanting to connect my extruder fan to it, and the other fan port to the part cooling fan.
Since this was posted so recently I’m hoping someone can help me with my problem because I’m not 100% sure this video tutorial is exactly what I need but I’ll try it anyway. I have a flyingbear P905 and it does not come stock with a part cooling fan to help cool my prints during printing and I don’t want to just plug the part cooling fan in on the 12/24v GND white plug between red X axis motor plug and the screw hole otherwise the part cooling fan will be one 100% of the time. I actually want the code to work and auto turn the part cooling fan on when it’s supposed to during a print after the first layer and for the hot end fam to turn on properly after the extruder reads past 50C as it says in the configuration.h folder. Currently my C.h folder is showing my motherboard as BOARD_MKS_13 and so if all I need to do is change that to RAMPS-14-EFF and I’m set to go then awesome but if not I don’t want to be fumbling around myself not knowing what to do and instead that’s why I’m asking on here to see if anyone has figured it out already. Thank you for the videos and anyone’s help is greatly appreciated!
Well sounds like a different 3d motherboard. If the chipset matches the RAMPS give it a try. One way to find out is the open pins.h file for your board and see if it points to Pins_Ramps.h. also you can control fans via gcodes in slic3r and in pronterface. Keep in mind to check pinouts diagram. If you're not sure research more. Also, what's the initial problem that is making you want to modify printer? Sounds like a print issue.
It is the exact same as in your video the MKS Gen L V1.0 and currently I've now run into a bigger problem is now my arduino ill not send any more compiles to the board. the port option under Tools isnt even highlighted to be selected when my board is plugged in andthe auto home commant from my LCD controller does nothing and my stepper motor chips are getting extremely hot when the board is plugged in to power from the power supply. Ugg I'm no Computer engineer but a diy printer should not be this complicated. I'm sure some user error is involved on my part but this time it just happened without me changing the code at all. No COM3 and port is unable to be clicked on. now i really want to just get a new fresh board. Possibly something that already has more than one port for a fan.
Not sure about flying bear board, but check the last change you did on the board removing components and then check USB port availablility. Most times it's a stepper board.
Is there anyway id be able to contact you and get help on setting up am MKS gen L1.0 board. iv been trying to follow your tutorials. but seem to be stuck.
I'm available only via UA-cam comments field. So what issues are you seeing?
@@EdwardBraiman i recently got a Gen L board to replace the board on my Anet A8. i have dual z steppers. which i need to have running. but i cant get any of the steppers to work. (i dont have stepper drivers the guy at the shop didnt say i needed them so i didn't get.) But i am heading back there a bit later as i assume i do need them. . I have a cooling fan (split too 2 fans. one on the v3d hotend and the other cooling motors.) that i cant seem to get to work. I know it is working. i can use my old board to test. just not the the mks board. I did get the reprap screen working. and my thrmister for my bed isnt registering.
I'll post after work today a couple of video links in my MKS Gen L playlist each tutorial, but if you find them first let me know. They will hopefully get you moving in the right direction.
@@russiank312 When you connect the Fans can you describe what is occurring? Do you have and know how to use a multimeter? What software versions are you using to communicate with the Printers motherboard? What Gcode(s) commands are you using?
@@EdwardBraiman well iv managed to find a few diagrams and i see i was connecting the one fan to the wrong place. I'm supposed to use the other hot end port for fans that always need to be on. i don't have a multi meter. but i do know how to use one. i can always borrow. i just bought stepper drivers
i cant activate my hotend fan on mks gen l. it is connected to he1
You want to connect second fan to Hbed. Let me know if this helps?
wiring on my tevo michelangelo like that and it works however on ender 3 i couldnt do it. used different boards.. so far no chance. and i know im missing something but dont know what.
btw i can heat nozzle and bed so there is no electrical issue i think. but i cant read voltage with multimeter by touching to flat screws.this is going to end with external mosfet for bed. maybe then i can use fans with hotbed port
In the video the bed or hbed port was used for second fan. The reason was because the architecture used by the board is the same as Ramps 1.4. which board are you using?
Edward Braiman mks gen l. i defined e0 auton fan pin 7 and it work it. he1 was d7
But then I cant heat up my bed, right?
Correct, but this is just showing another method of printing as I've covered in my RAMPS tutorials multiple ways to build and use Marlin firmware. Keep in mind I personally avoid using a heat bed, but it's still possible to use multiple extruders, fans and heat beds at the same time with Marlin firmware on either RAMPS 1.4 or MKS Gen L boards. I'll be doing another video soon explaining how to add additional fans in custom situations.
is it for any mks gen? Thank you.
The extruder is for almost all 3d printer boards that have two or motor extruder motor ports. The motherboard name in the file might point to ramps 1.4, but you can change after finding file in Marlin for boards.h and finding name of MKS gen L v1.0.
You can find MKS Gen L version 1.0 on eBay or Amazon or Google. It's priced around 18 to 25 dollars.
