My Summa really bugs me...

Have a Summa S2 160 T series. Don't get me wrong, it's a great plotter, most of the time. But having one issue that annoys me to no end, and sometimes screws up the job at hand.

So let's say I have something I'm cutting that's 48" long. When I send the job, it will begin cutting. Somewhere during the cut (usually near the end of the cut length) it will decide "HEY! I need an extra 3 feet of vinyl rolled out, because, ya know, there's only like another foot left of this job". So it will pause the cut, feed out another 3 feet (or more I've seen!) of vinyl, then return back to where it was cutting, and finish the job. After I cut off the completed job, then I have 3 feet of extra slack hanging off the back that I have to roooolllll back up to put the roll away.
Where this has been a big problem is when I cut a job that's, let's say, 48" long. And I have a roll of vinyl, still on the core, that I know is 60" long. PLENTY of vinyl right? WRONG. When It gets halfway, and it does it's thing I just described, then the end of the roll and the core jams up in the back of the plotter and the job is ruined.

Does anyone know how to STOP this plotter from pausing to feed all this useless extra vinyl, and simply cut in the allotted length? I have since learned to take the vinyl off the core IF it's a short run like the second scenario described. But still this is annoying even on a full roll, and takes extra time cutting a job when it thinks it has to stop and feed out WAY more than it even needs for the job.
