Greetings,
I make custom rulers by engraving aluminum and have discovered today that all my rulers were coming out too short. Distances varied from 1/16th in to 1/2in over a distance of 24 inches. I only use one pinch roller and do not use a carrier. I run the metal directly through the pinch rollers. I noticed the wheel was gummed up so I cleaned it, and it did not make any difference. It still always came up short. Out of desperation I tried another pinch roller and it worked perfect. Roller 2, 3, and 4 2 work ok. Roller 1 will not work no matter what I try. Does anyone know how to fix it or have ideas to troubleshoot it?
