I went through the calibration several times, but somehow the nozzle keeps hitting the bed. I have a QQ-S Pro (Delta).

M561 ; clear any bed transform

; Probe the bed at 3 peripheral and 3 halfway points, and perform 6-factor auto compensation

; Before running this, you should have set up your Z-probe trigger height to suit your build, in the G31 command in config.g.

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors

; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)
