Hello I have the kl4030 motor and driver kit which work well came with the c10 breakout board . Had to get a smooth stepper because Windows 10 couldn't get parallel port to work. Motion is fine I can run sample programs fine. After constructing a floating torch plate and trying to get homing working in mach 3 I had no success the m3 homing light comes on when enabled and with active low it turns off when switch is tripped it does not light back up . I checked pin 13 on breakout board and no voltage with multimeter so I think some how pins 10-15 have no power , have the pull up jumper set for inputs ....im lost any help would be appreciated
