My cutter has suddenly stopped cutting through the media. The test cut cuts the first 1/8 inch or so , then just cuts the surface of the media. I was trying to cut HTV, but thought it might be the problem so changed to cardstock using the setting I always use. Same result. Gradually increasing the pressure to the maximum made no difference. The mat is flat, the medium is brayered on. I changed to a new blade, Checked that it was protruding the right amount, and used the height tool to make sure the holder was set the right distance above the medium. The blade holder is tight in the carriage, and the carriage moves freely.
I thought that SCAL5 might be the problem. As I already have SCAL4, I tried that. Same result
