I recently purchased a new Ramps 1.4 with sprinter firmware but am having some trouble setting it up. None of my motors will move. I have the board successfully connected to pronterface, but all axis behave the same way. When I send the command the motor will make a little noise and appear like its trying to move but none of them will budge. It almost looks like when I send a command to move the motor instead works to stay in place. Like my old board constantly ran the motors in a hold position. That seems to be what they are doing.
I have checked all of the opto sensors, they are functioning properly. When I block one and send the command the motor does not make a sound. I have tried adjusting the pot on the motor driver and adjusting the firmware values for the opto sensors. I am using a 500w power supply with a few of the rails tied together. I know they are not mechanically blocked because my old board moved them fine. Do you have any suggestions? Maybe I can check for a certain volt/amp range going to each motor? Please help I have been stuck here for days.
