When I raise the roller enough for the laser to go under
it with out being hit, I get skipped stitches. I have reconstructed the laser case by removing the bottom wing nut and the plastic top and still I have a problem. It's when I have a large queen or king size quilt on the frame and have to use the laser in a sharp vertical position instead of a flat, horizontal position. The large size quilts leave no room to angle the laser and it is practically striaght up and down. I can't think of anything else to do that would give help.
