Ok, the setup is aluminum dog tags in a Drafboard jig. Since we have 2 Glowforges we can compare behavior. The first Glowforge (i.e. mine) works as expected. I click Set Focus and it deploys the laser where I expect (although not a huge fan of the new square, versus the old cross hair as the square is big) Anyway it correctly gets 0.2" height. And then lasing works perfectly. However on the other GF in the lab (XYK-336 under @Mike.Vet ) it selects the center of the dog tag (0.02") then when I fire off the job goes and selects a NEW spot (not on the tag). If you recall this GF (a Plus) had a fail I reported where it selected a random spot not on the tag before:
It also isn’t cutting through Proofgrade all the way, which I suspect is the same issue.
Troubleshooting, has been cleaning optics, rebooting GF.
Also weird was I selected the tag center for focus, which it did, then when I started the engrave, it did this spot and of course selected half-tag and half-draftboard, which meant it had no idea of the material
Versus on my machine (which does not do the random focus spot):
We have tried numerous times and get the same refocus behavior and can’t get past it. Both machines have undergone the new calibration.
