We have an S2 T series that we have been using for years with mainly no problems for the smaller cut jobs. For some reason I have a problem with jobs over 8' and it is hit or miss with being accurate. I did two 8' prints today and it cut perfect and then on the third it was off as soon as it started. It reads the marks no problem and the xy bar at the front and then it goes all the way to the back and is off as soon as it starts. After that I tried a 10' job that is only cutting text with a border so nothing complex and it did the same thing. I did a small 2' cut job after and it worked perfect. Does anyone else have these problems with longer cuts? I got this because the rep said summa was better for longer cut jobs but I can't seem to figure out why it is cutting off right away after it reads all the marks just fine.
