Hello,
I have a Sumpod Aluminium with RAMPS 1.4 and Arduino Mega 2560. When I upload the test script everything works fine: LEDs flashing, axis moving back and forth, hotbed and hotend getting hot. When I install Marlin and I want to try manual movements, only the Z axis moves back and forth while all the others don't respond to commands sent and heater/hotbed don't get hot.
Where do you think there is the problem?
