      When I try to do mesh bed leveling I home my printer It successfully does that then when I go to use G29 the printer goes to x100 y-60 and deploys probe and tries to probe in thin air.

        @idaho-creator said in G29 doesnt use the M557:

        G31 P500 X150 Y150 Z2.5 ; set Z probe trigger value, offset and trigger height

        Your probe is probably not 150mm away from the nozzle in X and Y I'm guessing. You'll have to measure the actual distance.

          Measured it to be x145 and y160. but when I enter g29 it goes to x120 Y-60 and not X50 Y50
