Woffler,
Do you actually have the DMM hardware in your possession?

not sure what you mean by "step angle". I did run across some settings that someone was using.

I never got a response for my last email or two from the DMM people so I started to look elsewhere for some more rugged industrial drives and have been collecting Yaskawa and Mitsubishi motors and drivers.

I pieced together the equivalent of a 3 axis 400W mitsubishi system for roughly half the cost of the DMM system minus the BoB.
