G32 tries to go negative on X axis

[hbrownell]

Thanks for the help folks, moving on to the next round, G32. It does the first probe just fine, but then X tries to go negative and rubs the belt (that da-da-da-da-da sound) but then continues on to the rest. I can't find where the odd plot number is..

Please post your full config.g and homeall.g as well.

Need to see your probe offset.

@hbrownell said in G32 tries to go negative on X axis:

M208 X20

This means that when your X endstop is triggered your nozzle is actually at 20mm inside of the bed surface? Is that correct? Or do you mean it's 20mm outside of the bed surface?
