Hello,
I am using Kcam and probotix driver circuits. My X axis directional pin (pin 3 of the parallel port) changes the Voltage from 3.25V to 4.7V instead of moving from 3.25V to 0V when the software prompts the motor driver circuit to change direction. Therefore my Motor is not changing direction. I have checked the driver circuits with other Directional pins onthe break out board and they turned out to be ok.
I have tried to invert the pin the set up but this still has not worked. Please advise me on how i can solve this problem |
