I'm been slowly commissioning a CoreXY machine. I've been using a carbon fiber filled PETG filament for rigidity and better heat resistance. The stepper brackets are fastened securely to a 20x20 anodized aluminum frame and the steppers are fastened to brackets using the usual 3mm screws. I've not attached any bonding wires between the frame and motors.

On a whim this morning after reading this thread, I check for continuity between my printer frame and the steppers and I have about 30 KOhms resistance between the body of the steppers and the mains ground. It's not highly conductive, but it's enough to be considered static dissipative and prevent a build up.

@dc42 That fits pretty well. I often flip back and forth between my desktop and my laptop.

I'll wait for 2.0 to sort it then.

So…just as an update here, I moved to 1.21RC5 and the crashes got less frequent, but were still happening occasionally. Then I finally remembered to pickup a new network cable, and it's been stable for 48 hours now. So....fixed, I think!
