How to find the right pin and Port for my PWM / and or Analog voltage output?

First of all Smooth stepper is not a BOB it's a motion controller. You will attach a BOB to the smooth stepper and here you need to know the pins to use.

Looks to me like your using a pre-built control box so give us details and will take better look. The manual should give all the details you need.

However I can see from the first picture that you have PWM and 0-10V Analog output. The Analog output could be used with the VFD for Speed reference. Output 1 would be used to turn ON/OFF the spindle.

Edit: PS Cannot see the mach3 settings on the pictures you need better pictures.
