Thank you for welcoming me to this forum. I've used Mach3 on my CNC Router for about two years now.
I've recently upgraded to a new desktop computer (Windows7, unfortunately), and when trying to run Mach3 it states "VB Failure. Check System". What does this mean?
Probably related, I have not been able to get Mach3 to control the CNC. Mach3 states that the Com Port 1 is not open or active, but the operating system says it is. Suggestions?
