Hello All,
I"m having a problem with Mach3 worked fine last time I used it bit now when I open the mach3 loader and select my 540BVFD windows shuts down and restarts. I running windows 7 Pro not sure whats going on any help would be greatly appreciated.

thanks Ed

Hello Ed,

This is an issue with a recent Windows 7 Update not agreeing with how Mach3 uses the parallel port. You can uninstall the recent update to fix this issue. I included a link below on how to do that and some of the known updates that cause this problem. You can also do a system restore to a saved point on your computer. Another option is to upgrade to an external motion controller, which do not have this issue.
