Portrait 3 suddenly cutting wrong between sheets
Hi! I have a portrait 3 that’s been working ok so far with some occasional registration mark reading issues. It’s been a lot better about that lately since I’ve learned to keep the lid closed while it reads the marks.
I typically cut white matte vinyl sticker paper. Cutting the first sheet went just fine and the cuts were perfect. Then the next sheet, it was misaligned. I tried a different sheet, misaligned. To be clear, these are different files/designs, not the same as the first one. Reloading the sheet, manually aligning the blade to read the mark, wiping the camera/laser area, and coloring the mark with black wasn’t working. Calibration test, looks perfect.
I made a new file following silhouette’s instruction video to rule out any file/scaling issues. It’s misaligned all over—using offset won’t work. I cut a second one and it’s misaligned roughly in the same spots. These were cut on copy paper to rule out material issues. You can see this cut in the first photo and the second photo is a calibration test done right after.
Anyone know what could be the problem? It happened literally between cuts. I also reached out to support who directed me to that video but I’m hoping someone here might have an idea. TIA
SOLVED: The mat wasn’t sticky enough. The paper was buckling causing cuts to be skewed. Switching it out with another one fixed the problem
