The problem is this, if launch a G32 all are correct probing bed in the 3 point defined in my setting. If i launch G29 head go down 10mm bed center and move to my defined point x0 y80 and crash head in bed ! Why i have missed ?

the probe is : 0.4mm top of nozzle
diameter : 200mm
height : 200mm

help my please :-(

Repetier

Your description is not clear enough to see any error. In general G32 and G29 use the same routine for measuring z height, so if one works the other should work as well and G30 the same. But you should not use G29 if you have G32 which is better.

The only thing that could be is the for some reason the probe did not trigger during G29 which of course causes the crash or if printer was not homed on G29.
