Everything is working now, i get forward and backward movement with the pins set up the way i told you, everything seems to be working as it should.

Good!

Just been reading that manual and it looks like you can remove the GND wires from the PUL- and Step- if you are still having issues.

Excerpt from PM542 manual -

This driver uses differential inputs to increase noise immunity and interface flexibility.

Single-ended control signals from the indexer/controller can also be accepted by this interface.

Still does not make sense but if its working then don't mess with it too much!
