Hi all,

I have a problem with a set up that consist of the the following gear;
G203V
Nema 34 - 640oz/in
MB-03 V1 BOB

All seems to be wired correctly, and the motor holds but wont turn when Mach3 is jogged.

I've been through the Mach3 setup process a few times and pins/ports and other assignments seem to be okay.

I've measured the voltage between 2/com and 3/com on the BOB and always have 4.7V when powered up.

It would be my understanding the voltage should be 0V if there is no command is being given by Mach3. When it is being controlled I would expect a raise in voltage.

I've played around with some of the jumpers with no success.

Any thoughts?

Thanks

Ramon
