I have a problem with the y movement of my machine.
When i select y+1 in repetier, it moves, but with a very strange noise.
I have a video to show the problem here
Set the voltage of the stepper drivers to 0.6V
Set the voltage of the power supply to 12V
Tightened the belts (but not too tight!)
Does anyone know what this is? Is it a problem with my belts or are my stepper motors too weak?
