How retract height is calculated from maximum safe Z

Learn how the retract height written in the nesting file is derived from the maximum safe Z value and the board thickness.

1. With the top plane selected as Z origin reference, the retract height written in the nesting file equals the maximum safe Z value minus the board thickness.
