I checked and setting G54 zero does not affect teh homed state…anyhow, here is the parameter dump. also, touch plate is doing weird things, like not going to the right height?!? eg,,,plate is 6.57mm thick, after running the z axis could be anything from 3.0 to 7 or 8, and after words, if I return to zero, it is 10+ mm away from the workpeice?!?
