Hello,
I have a reprap prusa i3 rework. Connected to my ramps 1.4 shield is an Arduino mega 2560. I run it with marlin and pronterface. The problem is when I use pronterface my ramps have stopped working. The only thing that works is the powering of the heatbed, unlike the stepper motors and the extruder that doesn't get any power. I took away all the connected motors form the shield expect one. Then I tested to switch out the stepper motor driver with a spare part, but that didn't help at all. I have voltage into the shield and there are signs on the shield that it would have burned. I have also tried using another Arduino mega 2560 with no success. Does anyone know what might be wrong?
Thanks,
Axel
