Question on half step config

If you currently have that pin connected to an output on your Linuxcnc computer and Linuxcnc is commanding that output. You probably only need to find that parallel port output pin in your hal file and comment it out (probably a setp line). I will be honest none of the machines I've worked with use that pin. If yours is using the whole step input it is most likely just a direct connection to 5v or ground and not wasting an output. I have the documents for the drives at work I just can't remember what they say whether the pin needs pulled high or low for full steps. But I know disconnected is half

I looked up the manual today, "Logic 0" for full stepps is pin 8 pulled low (connected to ground). "Logic 1" is pin 8 high, 3.5-24v and it will float there if disconnected.

I hate floating pins.
They always bite when you have no time for trouble. Fix it to either potential.

Maybe I used bad terminology, the drive has an internal pull up, so the pin is either high or pulled low by something you've connected to it.

Better felling
