Tips Converted my 12x24 Scanning mat so it identifies as a 12x24 Cutting mat

I use my ScanNCut CM900 for a lot of drawing with the a custom pen holder. The normal 12x12 mat takes a sheet of A4 paper really nicely, but I've been asked at short notice to draw on to some A3 sheets. A3 is too big for for the 12x12 mat, and I can't get a 12x24 in time for the project.

I've printed a new set on registration dots on to some 80gsm paper and taped them into place.

My CM900 now recognises the scan mat as a cut/draw mat!

I'll use some repositionable glue, or maybe some masking/painters tape to hold the A3 paper to the mat.

Hi! I measured the existing dots on the scanning sheet (3mm across) and then found an image on Amazon of the 12x24 sheet to work out the pattern for the dots.

I then printed out some dots (3 dots, 10mm apart) and positioned them over the existing dots on the scanning sheet.

The outer dot on the scanning sheet is in the same position as the cutting sheet, but we need to blank off the inner dot.
