On Sunday, I used a large chunk of a medium maple plywood Proofgrade board to build a card box. Worked just fine.
Last night (Monday) I tried to cut a couple more pieces out of that exact same piece of Proofgrade board, and this time the laser failed to cut all the way through on both pieces.
Did Proofgrade settings get changed on Monday for this piece? I’m kinda unhappy that I had to waste material on a bad cut.
