I have a kern laser than initially cut through 1/4 inch wood like butter, but doesn't seem to make it any more. I've used it for about 30 hours since I got it with no adjustments, and kern thinks I need to make adjustments now to make it cut correctly again. It doesn't make sense to me? Any ideas?
Second...how big a laser do you need to cut 5/8 solid wood (anyone have one), and is it worth trying since the kerf may warp with the depth of cut?
Is this a cnc router only project?
