Parallel Port Stepper Control

Tue, 30 Nov 1999 00:11:00 EST

It seems like I'm not seeing all the parallel port bits in the drop down list.

The board I'm using assigns the following:
Pin#2-Bit 0 to X Step Pulse
Pin#3-Bit1 to X Direction
Pin#4-Bit 2 to Y Step Pulse
Pin#5-Bit3 to Y Direction
Pin#6-Bit 4 to Z Step Pulse
Pin#7-Bit5 to Z Direction

The drop down list only shows bits 1 to 31 as selectable. Is this a bug, or am I just confused? I'm asking because I have not been able to get any of the motors to move using the examples I've found in the forums.

If anyone is interested, I'm making a device that will read the hole patterns in old player piano rolls, and convert them to MIDI. Eventually, I would like to try and reproduce the rolls on new paper, but that is far more challenging I think.
