LPT pins 16 and 17 problems using

permalink

Hello,

I am using a new controller board that uses pin 16 to enable (enable 1) the steppers for axis control and pin 17 to run a relay (output 1)for the spindle. The problem is they seem to affect each other and when I set them up as stated above they turn the other on/off and if I can start the spindle it wont turn off whether by g-code or manual in mach 3. Anyone got ideas ?. If the LPT port is the problem I think I might be in trouble.

Cheers,
Brett.
