I was having an issue with Signlab 9.1 not talking to the Summa D75R plotter that I picked up to replace my vinyl express Q39 that would not read registration marks. Soon after I made the post I figured out my problem. The knife was set to Knife with OPOS instead of Knife only in Signlab.
Now I am trying to figure out the work flow via Signlab 9.1 for Summa registration marks and bar code for doing Print and Cut vinyl as well as perf cut for decals.
I figured why waste every one's time as the problem was solved. So now you know.
