seemingly random z movement during mesh bed levelling
Kia ora everybody,
and another inexplicable behaviour (at least for me):
during mesh be levelling on 2 points of 49 the z-axis moves up and down about 2 cms before doing it's normal little flutter dance. I already did a z-axis calibration as I interpreted this as a certain uncertainty on behalf of the printer regarding the whereabouts of the extruder. But, as expected it did the same thing again after that.
Printer hasn't been moved, just changed from smooth to textured sheet.
And live z was also a bit out of whack and had to be adjusted by 15micm downwards.
Any ideas appreciated.
