I am trying to use mach3 but i don't seem to any step or dir signals from my parallel port pins .... is there a way i can check that my parallel port is connected to my software .... when i go into my hardware device manager i seem to have several parallel ports , does this matter? and aslo my video card is integrated with my mother board does this make any difference...i have wired the stepper drives as per the pacific science ma6410 manual , that is 5v to the positive step and dir and the negetive step and dir to pins on the parallel port , could some one tell me the settings for the stepper motor outputs should they be active low or active high.. can't get my head around that parts as yet... derkiow
