When done calibrating, remove the sensor and replace the nozzle.

Make sure to also de-activate the sensor in your printer.cfg file by adding a # in front of [include S2DW.cfg]. Save and Restart when done.

Keep the sensor somewhere safe, it is a universal tool and can be used on other printer too if you wish.

The calibration process won't need to be done again unless the belts or print heads are adjusted/replaced.
