I am pretty sure my Z limit switch it not working. I went to home my machine and one of the sensors was tripped. Took them all out and checked them and the Z one is bad. I lost my Z home (don't ask) but my x and y are fine. So now I can either redo my soft limits but was wondering if there was a way to set the machine z = 0. That way when I fix the sensor I am all set and I don't have to worry about my machine thinking machine z0 is 4 inches higher than my machine can go.
