Hello all; In carving these pcb's for the encoder, I only have room to clamp one edge, the back edge of the pcb.
I carved a dead flat pocket about 30 thou deep and slightly larger than the raw pcb material, gouging out the left front corner so the board, when pulled left & forward, isn't riding the corner, but is located by the left & front edges of this plywood containing the milled pocket. But when I add a small board across the rear edge of the board and clamp down on it, the front edge of the board rises slightly, about 5 thou I'd SWAG. Is there a way to couple the y axis position to a small z axis shift so that the engraving tool will stay within a thou or so of the correct depth relative to the warped pcb's surface by driving the z deeper as y moves the table forward to work on the rear portion of the pcb. Something on the order of 5 thou down at the rear of the board, over a y travel of 1 inch, would help, a lot. I've read the pages about mapping screws, but ANAICT, that can only correct the same axis for errors and wear in that axis's drive, but I don't see a way to make z move as y moves. Is it there & I'm too dumb to find it? Thanks everybody. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
