Of all the routers I've built and wired up, the most frustrating part is running out of pins to attach extra devices. Now the LPT port is old school, and never designed to interface a complex CNC machine. To complicate things even more, the same LPT port is becoming obsolete!
Has anyone designed a better interface card, with more I/O connections?
Everyone has suggested using a USB pendant which has an MPG, remote Cycle Start, E-Stop, Pause, Jog buttons, etc..
But at the same time, I've heard that USB is not so good!
Has anyone used the "BLACK BOX" brand of I/O cards to interface a CNC to a PC?
