The probe would deploy and immediately retract then the printer would would move up on z a small way then deploy the probe, immediately retract then move up on z again before declaring a probe failure and stopping. Thinking I was having an issue with the new probe I replaced it with a clone BLTouch that performed the same way then again with a second clone that had identical behavior. That's 4 probes all with the same behavior. I could use a BLTouch guru to let me know what that failure type means and how I should troubleshoot from here.

I have checked the wiring closely and there are no visual problems that I can see.
