Form 3 Optics Test

Just received a new Form 3, and as a baseline (i.e. sanity check) printed an optics test.

The test failed in an odd way. The center piece, and 3 of the 4 corner columns printed correctly, but the remaining corner did not print. Actually, it seems as though the print was attempted, but it did not adhere to the build plate.

Come to find out, there is an updated optics test for the Form 3, and it prints correctly — almost (the smallest pillar doesn’t survive), but I digress.

So why can’t the original optics test be printed successfully on a Form 3?

Have tried two different (new) tanks, and have even tried another (new) Form 3. Same failure in each scenario.

Believe the only remaining test is for the folks at Formlabs to try this themselves.
