Ramps 1.4 not moving motors
December 07, 2012 11:28PM
I have started building a Rostock printer. I am using RAMPS 1.4 from reprapdiscount on ebay. with pronterface for windows. and Allegro’s easy-to-use A4982 stepper driver. Im using Marlin V1 modified firmware for rostock. I am getting 12v out of power supply but only .49 to 1.43 volts at the drivers???? the firmware compiled fine and i am able to connect from pronterface.

You probably have to ask reprapdiscount.
