Phil…..most Chinese plotters are simply clones…….different names but basically the same….these plotters use standard hpgl drivers…….Roland drivers seem to work well because you can use one that matches you plotter width.
USB connections are usually usb /serial convertors and can be a pain to set up…..old fashioned serial will work just as well but use the supplied lead because there are 2 types.
Blade offset ( nornally 0.25mm on a roland blade ) and overcut can only be set up in the software…..as you know Corel on its own s not going to work…..at the very least a plugin will be needed.
When correctly set up most Chinese cutters are actually very good if a bit noisier than brand name competition.
Rob….I know what you mean but schools now have routers, embroidery machines, laser cutters etc……………..far cry from when I was at school.
