Hello everyone, In this winter break I had time to build a 3D printer (wanted one a few years ago) , now I want to make an dual extruder, and my Control Board (MKS Gen 1.4) has only 4 MOSFETs outputs: two for EXTRUDER HEATERS one for heatbed one for a fan I used already all the mosfets but I nee…

Thank you, tomorrow I will mount the module next to the main control board and use a free pin (i think I have 4 servo headers, and only use one for z touch probe) to provide the signal to L9110-S module

Just as a warning for others wanting to drive 12v motors with this little module, I connected a 12v turbine fan, but after about 2 weeks the first channel of that module did not worked anymore, no signs of burned parts, I moved the fan to the second channel, and tried again, it worked for a few days…

I hate magic smoke. Clearly the module can't manage 12v for a long time or something is messed up. Is the 3-D printer run by an arduino? If so, PLEASE tell me where to find instructions!

Yes, the 3D printer is run by an arduino, ATMEGA (I use a MKS Gen 1.4 board). What instructions do you need ? I attached a photo with my main controller and the MOSFET module I use now to drive the fan, connector to the second servo pin available (orange - yellow cable goes from the right side ser…

By instructions I mean video, instructable, or forum post. I just want to know how to make this, I have always wanted to make a 3-d printer wit arduino, but I figured that it was way over my head. I was also wondering, have you checked you circuits and motors for shorts? I have seen much magic smoke…

A few weeks later, the IRF5305s module is working perfect with the small fan. @KingDubDub if you don't have a lot of tools and time to make your own 3D printer I strongly recommend buying an Creality 3D printer, for $300, or a Prusa for $700, you can't make a better one, believe me. I made it mysel…

Thanks for that! I wanted to build my own but didn't know how much it would cost, I will look into the Creality and Prusa printers, maybe I will make my own someday. I'd rather make my own tools and machines then buy them, but I probably need more experience before I do that. Congrats on the fix!

Yes, it can drive 12V devices, just like it says in the description. The 12V refers to the output, not the input signals coming from the arduino
