    I just got my machine put together. did all the wiring and moved onto the ramps board. I flashed it with the firmware without LCD. I purchased everything from other sources except the wiring harnesses.

    The issue I am having is that I tried plugging in just the z access and controlling with repetier host manually and the machine says it connects fine and everything looks fine in the software. My stepper does nothing, not even a hum from the motor. When I plug in the ramps board before firing up the software a light on the ramps board flashes a few times green then goes out, under I can see a green light on the mega board. I have the 100ohm resistor on T0. Just trying to control one stepper at the moment. I have tried both on my mac downloading the driver and changing the baud rate, then tried re-flashing and controlling using a windows machine and get the same result.

    Any ideas?

    Ah, but how? There will likely be someone else with the same problem that would appreciate the solution.

    I thought you could just use the barrel connector to the mega for power to ramps, didnt know I needed to cut it off and connect it to the ramps board.
