Hey,
We are building a 3D printer using ramps 1.4, arduino mega and some old computer electronics. It all worked, until yesterday, when we flashed reconfigured marlin firmware once again. Now we can't get anything to work. Only things that do work are the extruder thermistor and the heated bed. Stepper motors do not block anymore when plugged in. The leds of the fan and extruder heater do not light up either. We have tried flashing a clean marlin firmware and repetier, with only the basic things configured and it does not work. We also tried removing the stepper drivers one by one to see if one of them could be broken. Ideas anyone?
kind regards
