There seems to be a wobble (back and forth movement) with clamp B that is cutting some parts of the paper, iron on and glitter card stock. I have tried changing the blade, tried using the deep cut blade/housing, a new mat and using the appropriate setting on the machine for the materials I am using. Nothing has help. It’s time consuming, labor intensive and frustrating having to go back and try to cut the image out with a razor blade by hand. It started to do this in September this year. So I’ve had the machine for about a year with no other issues with any materials (perm vinyl, glitter vinyl, card stock, and iron on)
