@cynd11 is the master of print and cut. This was one of her primary use cases that she explored even before production units came out. So click on her avatar and navigate to the topics she has posted. You’ll learn a lot.
The above posted links demonstrate how it is done, but you have identified the key issue: the graphic in the GFUI lines up different from expected. It varies from machine to machine too. So aligning one pre-printed image on the material under the camera in the bed can be be accurate, lots of images across the bed will give different results.
Looks like support has chimed in here and they will see if your machine is within the 1/4" specs of accuracy in the alignment.
There are workarounds. There have been improvements. It keeps getting better. Stick with it and you’ll figure it out.
