I am having trouble getting my stepper motors to move, they simply hum when pots on driver is turned towards the minimum and click and lock when the current is turned up.
I am using ramps 1.4 (reprap discount) and standard 4 wire NEMA 17 stepper motors, I only have motors plugged into the ramps at the moment.
I have loaded Marlin but also tried sprinter
I have checked and double checked that wiring is correct (identified coil pair).
Pronterface seems to be working fine as I can connect, and get the motors to make some noise.
The only way the motors will show any sign of doing anything (locking, humming) is when i click the home button, the jog command does not seem to do anything.
Could it be an issue with power supply not providing enough current? I am using a ATX and have checked the voltage.
Or is it an issue with the configuration?
I also tried the mechanical switch in case this was causing the problem, but this did not seem to change anything.
I am a little lost as to what to try next, any help would be appreciated!!
