Hello! I have also been working on a geeetech printer. I have been working on the geeetech A20M. I have been trying to convert the 2 in 1 out nozzle to a 2 in 2 out nozzle on the Stock A20M motherboard - GT2560 V3. I have been having trouble configuring firmware for it though. I have tried manipulating several different stock firmware from Geeetechs website but none of them have worked. I have had two compile correctly but one version doesn't allow the LCD to work and the other version kind of works... the thermal settings are off, so when I set a temp for my extruders, it over shoots the temp by about 30C each. Also my printer homes fine, but when I start a print it homes the Z axis, goes up about 5 mm and then crashes back down into the limit switch. I know it has nothing to do with the limit switch or the gcode. I was hoping you would be kind enough to maybe share your firmware files. Please get back to me! thank you

I would start here https://www.mediafire.com/folder/apu54jzrrdcdu/Builds. I use this for my A20M with Marlin 2.0 and I had to remap my thermistors in the pins file. He also has a Github here https://github.com/Vertabreak. Let me know if you have any questions.

Great work! Is it fully working? Where to fix nozzle fan? Is it possible to use BLTouch or just capacitive sensor?

Thank You!

I am waiting on Hot end cable and connectors from Geeetech. Then I will fit it up. I am not sure about the BLTouch or capacitive sensor since I don't have either one yet. I will update as soon as the parts come in.

Thank you for the comment.

Thank you, I will follow the developments
