Hello- I've been running Mach 3 on a home made router for about 5 years now and more recently on a home made plasma machine for about 2 years. My plasma uses control hardware by Candcnc who also provide a Mach 3 screen with their setup optimized for plasma. On the Mach screen in the upper lefthand corner there is a pulldown menu under "file" that has various affiliated programs listed- on my machine I have "lazycam" (not used), "sheetcam", and "vcarve". Recently I've upgraded from Vcarve 7 to Vcarve 8 pro, and the program runs ok in stand alone mode, but when I try to run Vcarve via the pulldown menu, Mach 3 runs Vcarve 7. Vcarve 8 files won't run on earlier versions so I need Mach 3 to recognize the upgrade. Anyone have some advise on what/where I need to do? I have also posted a similar question on the Candcnc board. Thanks.
