We just got our summa up and running and were getting all the settings done on it. I went to do a test run with Flexi and used the Summaflex marks for contour cutting. When I load the material and go to cut it says the cutter does not support the summa flex marks. Would anyone happen to know what I am doing wrong. I have been using a mutton and lining everything up manually for registration marks so I am all new to this automatic cutting.
