@Jrow my proposal would be to include the webcam PCB on the back of the Z axis of a CNC machine, and to mount the laser level permanently to the bed of the CNC.

The warm up routine would include a travel along X and also along Y, measuring the deviation in Z, then using that to build a grid of Z offset for mesh bed levelling. You could also measure Z backlash and compensate for it.

@jrow might be helpful to include what versions of the firmware and DWC you're running

@sinned6915 if you're accounting for stock skew use G68 https://docs.duet3d.com/en/User_manual/Reference/Gcodes#g68-coordinate-rotation

@dc42 consider my request for canned cycles low priority then!

@jrow Could it be a problem with pressure advance? Maybe the corners were triggering a pressure advance thing that was too much.

I've figured out what might've been my problem, and I suspect it's not related to my wiring, the filter, VFI or spindle. The wall outlet I was originally plugged in to had a faulty ground; confirmed by a plug tester. When I switched over to the extension lead from another breaker and a functioning ground, I may have let charge from the CNC itself exit via the new ground.

The reason I suspect this is because after discovering the faulty ground, I switched the power back over, and used a non-contact voltage detector all around my workshop, and found that the CNC, and even a wooden table had current in them. It's time to get the electrician over I think. This is above my paygrade.

Regarding the Meanwell clone; for now that's just handling my steppers, and the Duet. But I may have the budget for a proper supply in due course, and as you say it's probably a good idea.

I'll check the resistance on the spindle etc shortly. My VFD's UVW connectors are showing some continuance between one pair, but not between the other. I suspect that's going to be due to the component that blew up inside it.

@jrow nevermind. Had to flip the signal and ground wires on the other one for some reason.
