Start by following the steps/using the original gcode from jkoether: [https://www.printables.com/model/360303-auto-incrementing-first-layer-calibration](https://www.printables.com/model/360303-auto-incrementing-first-layer-calibration). Once you have chosen the best live-z setting using his original gcode, then use the 0.01mm increment file in my remix. This will help you further pinpoint the right live-z height.

If you really want to fine-tune further, you can use the 0.005mm increment remix. Any time I get a new steel sheet or do a nozzle swap I use jkoether's model and my two remixes to get a very precise live-z quickly.
