My VSI-540I recently has been cutting terrible. I replaced the cut strip and installed a new roland OEM 60 degree blade and it still doesn't cut all the way through the media. It just scores the top part of the media. The material is 21 mil thick , but I have never had any issues in the past. Attached is a picture of the test cut. It first cuts a line to the right , then it goes to the test cut. Which is something that I have never seen. Thanks for any help!
