I'm new to this, so hopefully this is really simple.

I downloaded the 1024.set screens.  When I go to the diagnostics screen and click on any of the spindle, flood, or mist toggles - Output #1 LED flashes.  The code for the toggles seems correct, and the code for the LEDs 1-3 seem right - so why do I have this problem?

Under the ports and pins (spindle Tab) is where you set the output that is running the spindle...
