I bought a PNC-1000 for $20. I've got a decent USB<->serial cable, a laptop running Linux, InkScape and InkCut working. I can technically connect to the Roland, but can't get it to do anything...So I'm looking for a PNC-1000 manual to see if there's something I've missed or wasn't able to glean on my own through Googling and such. Does anyone have a link available to a manual for this cutter? Thanks!
