![]() Looking through accessories>system tools>system information I can see a list of resources per device. ![]() LPT1 (onboard) has a resources tab, but LPT2 and LPT3 (PCI) do not. This doesn't work, so I investigated further and went to Device manager to find the resources tab. When I bring up mach3 it looks for the second port at 0x278, where it's supposed to be. ![]() The PCI card installs smoothly enough and doesn't throw up any nasties on the way. Port 2: Value twin PCI Parallel port adaptor, RS part number 449-2510, probably a cat in a bag as I've seen the same ones for £8 on Ebay and RS had £40 off me for itĬontrol/isolation: 9v control circuit, relayed/opto'd for safety, in-house design my m'self. Port 1: LPT1 (onboard) works fine and sends the steppers up and down marvellously Stepper controller: Routout 10-amp controller, works fine PC: no-name beige box, 900MHz Celeron, 512MB, no vices as such Mill: Pinnacle CNC vertical mill, 3-axis stepper, 4hp motor, controlled coolant, spindle, pneumatic brake, pneumatic drawbar. In principle my machine should work, but I've had no luck in getting mach3 to talk to the PCI parallel port card I've got.
