Hello, we are a makerspace in Lahore, Pakistan and we are using a custom printer from AB3D. Unfortunately we have a hard time getting it to run. It uses the RAMPS 1.4, Marlin and Repetier Host. Motors and fan seem to be moving moving correctly, but the bed and the extruder are not heating up when controlled through repetier. When we manually send 5v to pin 8 & 10 (bed & extruder) both heat up, and the thermistors show the right temperature, so I guess its not a hardware problem, but its somewhere in the firmware. We checked all the settings in pin.h and pin_ramps_14.h and they seem to be correct (although I could be wring of course)
Do you have any idea what else we could try? Any help much appreciated.
