First time submitting here - how long should calibration take? My Titan III was messing up just the characters near the front right edge of the vinyl plus one or two farther down the right edge. I fixed the blade offset, made sure the rollers were lined up, tightened the thumbscrews and I have the cutter set up with the edge of the vinyl 1" from the right side. Then I cleaned the surface under the vinyl and believe I discovered the problem, but now calibration is taking forever!! How long should it take, and is there anything I'm missing? Thank you in advance for your help!
