Ok, while I am waiting for the new break-out board, I need some help from the members on this forum.....

I want to fix my problem with the PWM output from Mach3. I had this working fine and then it mysteriously stopped.
I believe that this is nothing to do with the break-out board, and here is why, when I run the A axis outputs are all fine, when I turn off A axis and use one of these pins for PWM, I get nothing (same with the original B axis pin I was using). This is with everything unplugged.

Have played with all the settings I can find in Mach3, but still no output.

Found some posts with similar issues, but none with a resolution.

Anyone have some tips?
