I have an older Charmilles Robofil wire EDM that I'm trying to get running. It's a model CH-552 with type #2222 control & type #1222 power supply. When I use the commands MOV & MOR (basically like MDI move absolute & realtive) the machine works & cuts fine. When I use the commands CTA & CTR (manual machining absolute & realtive) the tank fills, power supply kicks in, the wire starts going, everything basically looks like it's kicking in to run but the machine will not move. If anyone has any experience with these machines I'd really appreciate any help offered. I haven't worked on one of these before so it may be something really simple that I don't know about. Thanks!
