Parallel Port Problem
I am using a simple, cheap motor controller-driver and I can't get the Z axis working. When checking the input voltages from the LPT Port, I am getting a negative voltage when trying to step. I have Z axis set on pins 6 & 7. Do not have this problem with the X & Y axis, they both work fine. I have tried this on 2 different PC's and get the same result on both of them. I don't have all the grounds(18-25) on my breadboard, but do have it on my controller board. Is this a ground issue, or something else? Any help would greatly be appreciated.
