Summa S2 Class 160 T Plotter | Sign Depot USA Training

← Back to Printing Summa S2 Class 160 T plotter

The short version

This plotter cuts vinyl. Most jobs are a kiss cut: it cuts the vinyl, but not the paper under it. It can also cut all the way through (FlexCut). Biggest cut: 62 inches wide. The blade is turned by a motor. That is the tangential head, and it is why corners come out sharp.

Watch: how this knife works

This machine is not a normal plotter. A motor turns the blade, so corners come out sharp. Watch this first.

▶ Watch (Summa video) Watch: load a roll of vinyl

How to load a roll and where the rollers go. About 7 minutes.

▶ Watch (Summa video) Watch: set the knife

How far the blade sticks out, and how hard it presses. This is the step that makes a clean kiss cut.

▶ Watch (Grimco video) Watch: cut all the way through (FlexCut)

FlexCut cuts through the vinyl and the paper, but leaves tiny bridges. The pieces stay on the roll until you pop them out.

▶ Watch (Summa video) Watch: the GoSign program

GoSign is the program on the computer that sends cuts to the plotter. This video shows how to bring in a file and send it. (Parts 1 and 2 of this series show how to install it and bring files in — Grimco's help page below has all three.)

▶ Watch (Summa video) Read: print, then cut (OPOS)

When a print has marks and the plotter has to cut around it, that is OPOS. There is no good video for this one, so read this page. The manual (below) has the full chapter.

Open the OPOS page (Grimco) Watch: clean the machine

What to clean, and how often. Clean machine, clean cuts.
