HELOOOOOOW

I use XP go in your BIOS (pres delete key wen your pc start ) and use &H378 in port setup

go in your bios and select 378 port in port setup i use wp

i use XP and u mas to do this go in port setup an do like the pic 2, 3, 4 - x-, y-, and z-axis step inputs, respectively. 6, 7, 8 - x-, y-, and z-axis direction inputs, respectively. Direction polarity depends on the motor connections. (to switch direction polarity, simply reverse the motor connections end-for-end) 13, 12, 11 - these PC connections are used to bring the controlled machinery (i.e. X-Y table) to a "home" position. Normally open (N.O.) switches are used here. u mast select &H378 or like in your bios see what are you have in your bios port setup and select bedirektion in your bios
