Summas support is also every bit as quick as their sales..... even on older long out of warranty machines. Our S160T is about 6 years old, still cuts dead accurate. I did recently have one of the X motors finally give out. Emailed Summa about it and one of their top engineers called here in under an hour. Went back and forth via email after that troubleshooting (did not know what the problem was at first) and quickly determined the issue, ordered a replacement motor and was up and running again literally within a couple of days. Long out of warranty and my only cost was the part itself. You can find where others have the same experience as well - Summas support is second to none. I'm in the middle of a project right now wrapping 8 buses with long term wraps. The logos are all overlays printed on pretty much the most expensive reflective money can buy (customer spec'ed), 48" roll of 3M 680. Each bus has a 16 foot long logo which is printed and cut as "one" cut job, there are also about 20 other smaller pieces/logos/units numbers, etc are all scattered about the same big sheet. The S160T absolutely nails it, one set of marks, it feeds the entire roughly 17 foot long sheet back and forth to detect the marks and cuts the entire thing. This is also laminated with 3M 8548 lam so it is dealing with a pretty thick heavy and long sheet. Keep in mind - due to the expensive nature of this material and the size, yes, we do slow the machine down for something this long. I'm not going to try and have it zoom a 17 foot long single sheet through at its maximum speeds. That would be wreckless.... We do try to break print/cut jobs down into smaller bites when possible keeping them in 4 to 8 foot sections. At those sizes we will run it at a much faster speed.
Over the years I've also cut much longer print/cut jobs as a single cut and it can pull it off no problem.
