Yeah, I was trying to ,make the roll length in the RIP (Flexi 8.5 as well) as long as I could and it stops about 25' short of the whole roll. I haven't tried extending my print boundaries, but will try it. The only thing I have found that almost religiously works (So long as you remember) is to reload the printer before you it print. Seems to confuse just how much vinyl has passed through. I just remembered this after waking up Sunday morning and being 2.5 panels short of what I told it to do...
