Centroid Community CNC Support Forum

I've had this recurring issue with CNC12 losing spindle control after running a program a few times. There are no drive faults or errors when this happens. I cannot manually turn the spindle on from the VCP or from MDI but I can enable the spindle If I go into the outputs page and manually force the VFD enable output. The only resolution for this issue is to power cycle acorn board. The interesting thing here is I still have axis control from the VCP and others like work lights and homing ect.

Any ideas?

I think I found the issue after monitoring the inputs/outputs page. Opening and closing the chuck output seems to fix the issue. There must be a problem with the chuck open close bit and vfd enable in the plc.


*Update*

There is an argument in the Standard spindle stage of the plc to check the status of a bit for the chuck open and close. For some reason the bit would not get set and would not allow VFD enable to be set. Not sure why this happens but omitting the bit check for ChuckOpenCloseComplete_M is a temporary solution. Not liable for throwing stock from your chuck

ALWAYS post a FRESH Report. Centroid DOES monitor these forums.
Do you have a hydraulic chuck you are opening and closing?

Yes this is a hydraulic chuck setup. I will to do some more investigating after I'm done with the current job I have on this machine.

please post a fresh report.zip when requesting support

I attached the wrong file in the original post.

You wired all your outputs to Ether1616?

Just looked at your report.
You are running on a BETA version of software (How did you get that? Are you a Beta Tester?)
