Hey, I got it to stop. What I found was when I had the machine run without the glass, it seemed like it was sticky and couldn’t pull the ring back to home along the blade. I started to use a skate guard and pushed it and it had no problem. I ended up cleaning the whole machine inside and out, then used just a tiny bit of grease on the inside along the rail that it runs on. Moved it. Sick and forth a bit and runs perfect again now.
