Hello everyone ,
Let me explain a little bit about what brought this subject up . I have a cnc router with a hp a1140n desktop pc with onboard printer port and it all works well with Mach3 and the router . I wanted to add a manual pulse generator (MPG) to make touching off with edge finder and trimming in holes...etc easier. I bought a mpg off ebay and I bought a Startech port pci parallel adapter card part# PCI1PECP after getting everything wired and hooked up and Mach3 configured the mpg will not work the selector switches work sometimes and the dial rotary encoder has never worked . I have got another mpg coming because the 1st one I got was bad . So the whole point to this story is when I turn off the computer somehow someway the configuration of this pci card changes itself . I'm not sure how or what is going on but has anyone else experienced this problem and what adapter card is recommended for using with a mpg ??? I downloaded a program that let's you change and monitor the pinout and this is how I found out the pci port was changing. Does anyone have any suggestions or help
