Yes, I know it IS a 48V. I want you to measure it with a Volt meter and make sure it is putting OUT the 48V it is supposed to. If you get a green light with everything disconnected from G540, than it is most likely not the culprit.

Just to be clear, You DID try it with everything hooked up and the charge pump switch in both positions, right?

Also, in motor tuning, make sure you have at least some velocity on the slider and the step pulse is set to at least 2.

Look at both ends of the DB25 cable and check for bent pins.
