Hello! I truly don’t know. There are so many problems with PTC. Maybe, it’s just a new bug in the latest update. Have you sent an Errors and Feedback report from the Help menu? They’ll probably send back a reply asking for a video of the problem. Maybe, they can get the bugs worked out in the next update. So many people have problems with the PTC. I honestly believe it’s because there is no Flatten option. Some people will say that’s not it, but I think it is. I suggested it in a previous post.
Maybe, take a look at this thread and see if the instructions I gave can help you?
I also suggest trying to create an offset for your offset and actually changing the offset colors to the background color of your printed image. Then, print your image. Then, cut using the smaller offset, rather than the offset you made for it. Just to combat any small misalignments you may get, if you get it back to cutting closer to your desired cut. Hope it helps. Let me know if it does. I know it’s frustrating. My Crafter never did get a good cut, but my iCraft has. Although, I’ve only done PTC with it the day after I received it, and haven’t done it since.
Oh, another question: Did you reset your calibration after 8-10 cals? If not, try resetting before you calibrate again.
Also, are you using images from the Loklik library or your own files?
Edit: This video from @InkiteeWorkshop just popped up on my feed. She suggests using the USB for calibration. Idk if this will change anything, but you can try.
