So I am using proofgrade walnut hardwood that’s 1/8” thickness. I make these back panels for some art I create. I use DRAFT GRAPHIC settings for the PG materials and it takes about 21mins to engrave and cut a perfect 5.9” square around the words.
Every time I create these back panels the proofgrade materials curve up. Some are worse than others.
Also the proofgrade materials are perfectly flat prior to cutting so they are not curved before I work on them.
Does anybody know
- why this is happening?
- how to stop it?
- how to “uncurve” the PG materials after the engrave?
