Has any one experienced KMotionCNC freezing when using an M00? It happens after about 5 to 10 cycles. When KMCNC hangs none of the on screen controls work nor does any of my physical switches for Cycle Start,Pause, Spindle off. The axis DROs stop also. Only thing that will bring it back is my E Stop switch.Here is the Gcode iam running. It will hang on v4.34i and v4.33.

I may also have noise from running spindle. As i have not experienced anything like this so far on this machine. But this is the first time i have had spindle running this fast, if that even matters? Its a 1.5HP 1740 RPM 3 phase motor. Using Contactors for Forward and Reverse control. RPM of spindle is adjusted with a variable speed pulley head. Anyone have any suggestions on where some noise filters should typically be placed with this possible issue?

Thanks,
Troy

Ok. Just did a quick test cutting air. Its defiantly something to do with spindle running. KMCNC hangs with no axis DRO movement, gcode keeps executing fine and mill keeps moving fine. I think it is noise getting into computer because when KMCNC hangs i tried launching Notepad or Calculator and get no response until i manually shut off spindle then KMCNC comes back and Notepad or Calculator launches.

The machine PC uses a power supply like a laptop and it was setting close to the DC power supply for servos. So placed it on the other side of cabinet,about 18" away, and got no hanging issues of KMotionCNC or any other functions.
After that i rerouted 120VAC for PC and added a inline noise filter for PC power. Did a test for about 10 minutes of running same Gcode with spindle RPM full speed and all looks ok now.
