Hello! I recently purchased a SC50 from USCutter. I've been using a 34" MH Series cutter for a few years now without any issues. However, I just upgraded to a Mac and I needed a larger cutter anyways so I bought the SC50. It's pretty similar to the MH series cutter so the setup was pretty simple for me. I paid Craft Edge $15 to have my license for SCAL4 Pro swapped over to my MacBook. I am using SCAL4 Pro on my MacBook now. The MacBook has OS Sierra 10.12.4on it. Anyways, I was attempting to cut my first job and the first time, it got about 1/4 of the way through and the cutter suddenly went all the way to the left and stayed there. Machine was making some odd noises. I made sure my computer wasn't going into sleep mode or something. The second time I tried the same job, it got about half way done and suddenly started spitting the entire roll of vinyl out to the end. I also put a cut right down the middle of all of it. About 15 feet of a 30" wide roll. I'm paranoid to try it again and ruin more vinyl. Any ideas on what could be causing this? Thanks!
