Hi Guys,
I'm new to this whole PC based CNC control stuff,but not to CNC (I've owned a CNC shop since 1983!). I have connected my laptop (running Mach3) via USB to a UC100 then into a Leanshine MX3660 3-axis drive. Everything have been configured correctly and I get no faults on the diognistics page and everything is correct on the UC100 in/out moniter... But I get no output voltage in any of the 4 output sets when the M3, M4, M7, M8 toggles are actuated. I also have the Pulse LEd enabled.
Am I doing something wrong or do i have a bad MX3660???
Thanks in advance for your help!

Do you have the outputs configured in Mach?
-
Yes, I have and everything within Mach 3 looks fine. I have added my motors and tuned them with no problem.
-
So it is all working now?
-
The problem was that Leadshine did not explain in their installation manual that the output leads were just for switching and that an additional power source (<24 VDC) must me provided. They have now modified their manual and provided me with the correct wiring diagram to attach the relays.
Leadshine was VERY helpful, Cnc4pc the exact opposite.

I just figured out what you have been saying. I saw the updated users manual. Disappointing but I do have an extra 5v supply in the cabinet that will work.
Are you running a VFD or inverter?
