Spindle run fault

Spindle run fault

Postby Sibbers » 19 Nov 2017, 20:00

Can anyone help.
I am having some issues with running the spindle since rebuilding my control box with a mk 3/4 controller and 3 new drivers. If i turn on my machine and lap top etc i can run my drivers with the spindle turning manually via the arrow keys on my lap top, but if i load up a gcode when I start routing the software goes into fault as if one of the limit switches has been activated, if I do the same with the spindle turned off, the router maps the the gcode perfect, but as soon as I turn on the spindle it stops working and all the control icons turn gray.
My current set up is a sxcnc control box with a NOWFOREVER spindle frequency converter and associated controller on the front of the box, with the planet cnc mk 3/4 controller with associated xyz motor drivers, I have fitted xyz limit switches wired in series and spindle drop sensor.

All symptoms that you described earlier are indicating problems caused by a electromagnetic interference:

This occurrence interferes with the USB communication, which as a results drops and communication between controller and PC is terminated.

You see, electro motors, VFDs etc...are sources of EMI and therefore your wiring and other devices should be properly shielded and filtered. You would need to use shielded cables and use line filters for VFD. Also controller needs to use external power supply for its stable operation.

Try this:
run your machine but without the spindle turned on. Try just air cutting your piece so that we see if spindle and its interference is to blame.
