Attempt Z Tilt -- Print Head Hitting Bed

Running klipper v0.11.0-91 Home All works fine. BLTouch probes as expected. Run Z-Tilt correction and the print head crashes into the bed at the first probe point!!!

Have reinstalled ratos and reconfigured the printer. Home All works. When I run Z-Tilt correction the BLTouch probe doesn't deploy and the printer head crashes.

Why is your horizontal_move_z so high? 12mm seems a lot

wanted to ensure there was plenty of clearance between the bed and the probe between moves. ok so horizontal_move_z is the clearance between the probe and the bed before a probe commences. This figure would not affect the probing operation only make it slower. Looks like it was a marginal BLTouch cable. BLTouch would probe around the centre of the bed but towards the edges it consistently failed to probe. Weird fault! 🥴
