5i25 with a Chinese parallel port BOB

The text file you have tells you which pin is which on the 5i25. But the picture you show does not really show what pin is what on the BoB.
But P1 as PWM is likely to be the only thing that matters (and is what that firmware has)
You can always swap the other wires round to suit.

Looks like it should work. The 5i25 has an encoder on the 11/12/13 pins, but if you do not need a spindle encode then set "num_encoders=0" in the config and those pins become ordinary inputs for limit switches.
