hi all;
i'm new on CNC and Mach 3 software , but I've done alot of projects on Parallel port using visual basic.
all pins of my parallel port works perfectly as expected with all software except Mach 3

I've assigned PIN 2 and PIN 3 for step and Dir of x-axis respectively. by monitoring parallel port i can see that these two pins does not respond at all. instead, non related pins starts blinking !
am i missing something ?

please i'm looking forward to see your comments

Have you gone into BIOS and made sure that the LPT ports are configured as EPP?

What operating system are you using? Do you have the correct port address in Mach3?

Is it a fresh install on the pc ? I swopped a drive over from an older pc into a new pc with mach3 and it didn't work. Had to reinstall ....

I would check the parrallel cable and make sure the pins are the same on both ends. "Straight through" parrallel cable.
