I'm still trying to get to grips with a Geeetech Prusa i3. I was using Pronterface and Slic3r reasonably well, although print quality was a bit rough. So I decided to try out Repetier instead. I then tried uploading Repetier firmware, which simply didn't work. I then re-uploaded the original Marlin firmware from the Geeetech website - so far so good.
BUT
Now I can connect to the printer and I can extrude filament, but the X, Y, and Z steppers aren't moving at all. There is a humming noise coming from the machine (I think it may be from the control board, but I'm not sure) whenever I send a command to move one of the axes.
Does anyone know what's going on?
