sorry for my english i'm using google translator:
I got a problem with my plotter pcut630, sometimes cut the vinyl to deep and other times only mark the vinyl, I already changed the blade for a new one and the pressure but it doesn't fix the problem in fact the blade looks like a blade very used.
I read in a web page that could be the stripe cushion of pvc, but i wanna be sure if could be this to buy it or maybe needs maintenance.
