General Mach Discussion / Re: New Guy . . . Old problem??? - motors not turning
« on: February 20, 2009, 06:00:29 PM »
I do see the drop to 0V (.1) when I jog the other way. Is there an advantage to running the system w/ enabled drivers? The manual for the drivers says they do not need to be enabled. I was trying not to change too much of the original wiring, but I don't have a problem doing so if needed.
I will trace the 5VDC to the drivers. I suspect that it is the wiring between the combo board and the drivers - the motors will operate when the drivers are set to test mode (1/2 turn each direction).
Would motor tuning have any effect at this point? I figured that if I have no reaction from the motors at all, they are not getting the signal.
Thanks again for your help.
