Hi, you can check that the driver board voltage (0.8-1.2v) may not have enough current to cause the extruder to not work properly. You can also refer to this:https://github.com/Geeetech3D/Prusa_I3_3Dprinter/blob/master/I3pro/Hardware_GT2560_RevA%2B.pdf


thanks for your indication ...

Hello everyone, I have a problem,

today after the thousandth print my extruder stopped working suddenly. I tried to invert both the drivers and the cables on the other axes ... they all work except the extruder channel.

I also found some guides to invert the pins of the extruder 0 with extruder 1 ...
