Proofgrade settings not working

it’s possible (though highly unlikely, I would assume) that there may be some possibility for each piece to have its own settings with very precise thickness measurements.

Since the machine only has 16 possible focus heights (0.0278" per step over a range of 0.417"), having a super precise measurement of the material thickness would seem to be unnecessary.
