=== Calibrating Tool Measure Plate ===
Only after resurfacing the spoil board, the tool measure plate position on the lower right of the machine needs to be recalibrated with the 'Calibrate Switch' button--this is a '''required and critical step'''. This button should '''not''' be used at any other time. This distance is the difference between the top of the tool measure plate and the top of the spoil board. The machine needs to know this height difference so tool measure operations are correct.

* The Touch Top and Measure Tool feature works without errors
⚫
* Before loading any G-Code, the Z Soft Limit is exceeded without the tool being close to the Spoilboard
