Hi Kyo, A quick question. When I click on the $H, the Z will move up to the sensor, stop, back off, slowly move towards the switch until it trips and then backs off 3mm. then the X and Y axis's do the same , except they both will only stop at the sensors and back off, then stop. They don't come back to the sensors so I have to run the $H again to make that happen? Any ideas.
