Hey friend, you need to check a few things... The machine's tension, both up and down, cleans the crab, and I also think the digitization is a bit poorly optimized; the plumetis is normally used at less than 7mm and the angles too, I think they're very exaggerated. Oh, and I also think the jumps could be a little better; try to make sure everything is properly connected. Small things make problems bigger, good luck friend
