My 4B was the absolute best plotter for making pounce patterns and I still have it hooked up in my garage. I always just reversed the layout then plotted, no need for sanding.
With the Graphtec I pen plotted then hand-cut my last patterns with a pounce wheel (they do come in various sizes) and to be honest it sucked in comparison to the 4B patterns.
I was told Graphtec does have a pounce attachment, which is one of the reasons I bought it, but have never been able to find one.
