Hi there,

An interesting issue appeared yesterday on my new build gantry router cnc. Its been running fine for a few weeks however yesterday as I was running gcode the machine would momentarily halt on random passes and then resume with the what appeared no loss of steps? It was happening in every type of process, I noticed it being worse however when the machine was under heaver load going through solid hardwood. I’ve never seem this before and wondered where I should start to look for the cause. It was like the machine was waiting to catch up with itself or self diagnose, not good though. I’ve got mach 3 set to a kernel speed 35.000Hz. I ran the mach3 driver test and it said it was in excellent health, no spikes.

Any ideas about where to start first to diagnose?

Thanks
