Title: No Output Voltage from Leadshine MX3660/ UC100
Post by: Joaquin Suave on November 20, 2013, 09:04:43 PM
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?
