Step 2

              Homing Z

During bed leveling, you want the probe position to be at the center of the bed, not the nozzle. Once you have your X and Y coordinates calculated press Home Z
The probe(not the nozzle) will move to the center of the bed, Deploy the probe, raise the bed, stop once the probe is triggered, and lower the bed.
If your probe is slightly off center we need to correct it. Manually jog the hotend so the probe is in the center of the bed. Note the coordinates
Take the coordinates off the web page and replace them in homez.g and homeall.g
