General Mach Discussion / Re: help with hp lap top running cnc controlor

The Mach3 driver takes over full control of the local parallel port and this is how it can change and read the status of individual pins, the USB to parallel hardware and software creates a local virtual port which Mach3's driver can take over but the hardware and software on the other side of the virtual port is out of sight to and not controlled by Mach3, is designed to read and write full data bytes on the port pins, and doesn't replicate the required pin states and timings needed for CNC
There are PC Card parallel port adapters available which give a PCI parallel port on laptops without one but they aren't cheap and I suspect you'd be better off putting the money into an external motion controller,
