Good afternoon,
I recently bought an MX4660, with plans to use this for a BF20VL (G0704) CNC conversion. I built a panel for the build and when I did my initial testing, everything was working fine, all three motors (nema 23 x 2 and nema 34 x 1) worked perfectly. After completing the panel, I started on the mill itself.
When I went to use the panel again around a week later, the motors let out a high pitched squealing/seizing noise the moment the driver is powered on, and won't accept any signal through mach3. This is regardless of whether it's connected to the smoothstepper or not, and is a problem on all of the axis.
Trouble shooting I have tried;
- Re-ran the wiring to the motor
- Re-ran the wiring to the power connector
- Isolated the driver from the panel with longer wiring to make sure it wasn't some sort of interference
- Tried 3 different motors, across the different axis, same problem regardless of axis, or motor.
It's got me absolutely baffled, it was working perfectly before. 1 week after I complete the panel, I go to hook it up and now it doesn't work at all.
Any ideas? Is it likely that the unit has just failed for some unknown reason?
Any help would be extremely appreciated, i'm pulling my hair out with this one.
Regards,
Dan
