I'm not sure if it is a software problem or cutter problem. I use coreldraw 2021 & flexiprint HP . The graphtec ce5000-60 I'm using cuts great on regular vinyl cutting. When I do a print/cut for contour cutting the cutter does not locate the registration mark. I bought another graphtec ce5000-60 on eBay. I set it up and did 4 print/cuts it worked perfectly. Come back the next day. This new-to-me cutter could not find the registration marks now. I've tried trouble shooting with the manual, with Youtube, and tried going thru Graphtec's website. Please Help
