I have a PRTalpha BT, software version 3.3.18 which I program with part wizard2. After having repairs done on my computer, I had to reinstall the shopbot software and the part wizard2. Now, it only outputs in linear format, (m's), it will not output in arc format, CG's) like it used to. Makes for long programs. Everything is intact including the postp folder in part wizard2 which includes arc_inch processor. I talked to a guy in tech support who sent me a new postprocessor but it didn't help. Does anyone know what's going on? Is there something I've got to reset somewhere?
