An enhancement to the Z probing options that allow the four corners of a work piece to be probed and would generate an algorithm that that would continuously correct the Z axis height as the router moves along the Y and X axis.

This would compensate for work pieces that are not of a consistent thickness. I realize using just the four corners isn't ideal as the surface of the work piece isn't a perfectly flat plane that is just not parallel to the bottom surface. Currently I add shims between the work piece and spoil board and can get acceptable results. It is very time consuming to probe the four corners, shim the low corner(s) and recheck.

I have seen acrylic sheet thickness vary 0.010" from one end to the other across 15". When engraving at a 0.005" depth this leaves some areas uncut.

Maybe have an option to probe up to 8 or 10 points anywhere on the surface of the work piece. Known high and low spots could be intentionally selected along with the four corners.  

Best regards,
