Did the new firmware change the way boards arepositioned? For marginal boards, I havebeen using two a 1/8” or ¼” strips or plywood/hardboard about 1” wide andlonger than the board attached to the bottom edges to even out the bottom. You can shim the center if the board is slightlybowed The little eye sees the ends, the roller tracks the distance traveled. But today (first time with new firmware),specifying stay under rollers and center, the board was positioned off theright roller and the carving – 12” x 36” – was about 3” to the right = $18wasted redwood. I cut a new piece and triedagain using the strips = doing the same thing. It measured the length correctly, but positioned the board wrong. Removed the strips and it worked fine. I tried jog to center and to corner, but boardcreeps to the left and ignores any key pushes until “possible board removal”.
