Only reason I asked what software was because summa did have multiple different softwares depending on when you purchased the machine. The go produce software does have edge recognition. It's called "Align with edges" output option to align direct cut jobs with the media edges using edge detection. Created the artboard to the exact sheet size you are using, center the graphics on the artboard with zero bleed, and then use that same file as the your cut. You can even common line cut this. Many customers use this method.
