Hi everyone,

I recently bought a CTC copy of the Prusa i3 and I tried to switch the motherboard since the one included did not have any prorammer. So I installed the RAMPS 1.4 and I was able to upload the Marlin firmware. Now the problem is that the only thing that seems to work is the LCD screen… I cannot heat the extruder nor the bed and I cannot move the X, Y or Z motor. I was able to change the printer’s name and switch the clockwise - counter clockwise of the clicker on the LCD.

Does someone has an idea what my problem could be?

Thank you all
