Vertical banding when engraving on clear acrylic

[eflyguy]

All I can say is that it’s always been an issue, was reported to support, and never addressed.

i.e.:

Power changes when doing 3d Engrave on PG acrylic (banding)

Yes. For some reason the machine introduces artificial banding even in solid areas - the example here uses rectangular vector objects. It varies by lpi. This was also Proofgrade acrylic. Acrylic shows the problem more than natural materials. [image] You can see it in the deeper (PG 3D engrave) sections of this piece, for example: [image]

The gift of good measure does not contain a large enough solid engrave area for them to show up. I agree with the earlier comment to change the LPI on what you were printing. Doesn’t matter if it they weren’t showing before, GF pushes updates all the time and something might have affected your engraves.

You’ve opened a support ticket by posting in Problems and Support, but they can’t help with non-Proofgrade materials. I’ve moved this to an appropriate forum.
