Problem: My Lathe spindle rarely, and randomly stops during a cnc program.
Background: I finally have all of my motors running, system calibrated and I am now "air cutting" using "simple" g-code generated with the Mach4 turn cycles. 3 times now, the spindle has "briefly frozen <1sec" mid run and then continued. There are no alarms raised, no software indicators or hardware alarms. It is unclear if any steps are missed.
The Machine:
Mach4 Hobby (Windows 10 dedicated (current) I5 computer),
PoKeys57CNC,
DMM-Tech Dyn4 controller, 400W servo,
Sherline 4410 Lathe,
X,Y axis standard Leadshine steppers and controllers.
I am Air cutting so there is no load on motors.
I am puzzled and looking for advice on how to diagnose the fault and ultimately correct it?
Since the event is random and "rare" being prepared to capture diagnostics is a problem too, so if anyone can suggest test to "force" the problem that would also be a help.
Thanks in advance.
