Hi,
I have assembled a prusa i2 with RAMPS 1.4 attached to the arduino board. I have loaded sprinter onto the arduino board and run pronterface. I can get the heat beds to heat up but the motors are not working. They dont make any noise or vibration either, theyre perfectly still. Can anyone help me troubleshoot this. I am in real need of help and any help is greatly appreciated.
Regards

Have you installed 3 jumpers under all the drivers?
Are the drivers fitted the correct way round?
Have you configured Sprinter for your set-up?

...and have you got 12v plugged into the 5A connector block (outside one) on the Ramps?

Could be an end stop problem... can you post photos of the end stops and your RAMPS wiring?
