Many things are needed for movement
12v on the 12v 5amp power input on the ramps is essential (not 5v, as many have accidentally done)
Having some sort of working stepper driver modules plugged into the correct location on the ramps
Setting the micro stepping jumpers on the ramps (under each stepper motor driver, 3 jumpers, all should be on)
Setting the current limiting pot on the stepper drivers
The mega programmed with a firmware that is setup for a ramps board
Stepper motors wired correctly onto the ramps.
End stops setup and working correctly.
Firstly let eliminate the the firmware and anything you could have done there
Download and upload to the mega the ramps test firmware from [
reprap.org]
This test firmware is only for the ramps, so you cant miss configure it
This will ignore all end stops and make all motors move backwards and forwards.
NB it will also turn on both hot end and heated bed without temperature control, so leave these un plugged or risk a burning.
Check those micro stepping jumpers exist.
Check you have 12v on the 12v 5amp plug
Power up the ramps with external 12v on with the test firmware. does anything happen?
take a clear photo of you current controller and post it here, so we can see if there is anything obvious.
