5i25 with a Chinese parallel port BOB

Hi I've just got my Mesa 5i25 I downloaded a firmware package from Mesa's site I noticed it has a piece of firmware called

5i25_5ABOBx2.bit

Can't find anything on it in the manual but it sounds promising.



Just wondering if anyone had used this file?

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.

This has the pins marked

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.
