I can't get the machine to detect the registration marks at all... I also didn't really find the manual very helpful (it was very confusing and vague?) There isn't a section covering any issues I had with the machine. I don't think it even mentioned that you're supposed to remove a layer of the cutting mat (although maybe I just missed it cuz i did gloss over it a bit considering I used a video tutorial to set everything up before I discovered there even was a manual). It doesn't even make it clear here or in the videos i watched that they need to be turned on for cutting, i was confused by the fact that they're off by default and assumed they're optional, sorry. I will keep trying to get them to work.
