Thank you for the reply. I am initially trying Windows 7 32 bit as some say it will work even without the vista patch. I am not operational at this point. Mach 3 makes a test move on screen but the mill does not respond. I do not believe the configuration settings are correct. I was missing the Camtronics shopservexml file so nothing was set. I contacted Camtronics and all I was given was the motor pin numbers. The previous owner found the original disk and is sending it, maybe that will help. I need the motor pin numbers, inputs, outputs, encoder and mpg's settings... IDK, not sure what all I exactly need to set up the Mach 3 settings to match the Camtronics controller on a Shopmaster Bridgemill 3 in 1. I will keep reading and learning...
