Examine https://softsolder.files.wordpress.c...d-overview.jpg for example, that looks to put X Step and Direction onto pins 2 and 14, respectively. The parallel port is configured - not by Mach, but by the utility of the parallel printer interface to provide 12 outputs and 5 inputs. These are hard bound to the whateveritis pins, and most BOBs will present these notionally for particular functions (like X step, X dir), but actually they are only generic inputs and outputs. There's nothing stopping you using a X-DIR for your Z-Step, for example, though you'd be sadistic to try (I did once swap one of the primary axis onto the A-Axis when one output on a BOB failed).

My one issue is that the OP changed many things, but not the BOB wiring (unless he didn't mention that). The pin mapping is... not the last thing that I'd check... but certainly not the first.

I've only had the pleasure of 3 machines, but probably enough architectural changes on two to get close to your five. I know that there isn't a hard pin mapping.
Literally havnt changed a thing - I found the XML file that comes with these and it matches the one I’m using. I’ve literally unplugged it from the power point and unplugged the parallel cable from to the pc and loaded it on to a trailer - moved then plugged it back in again.
Now I think of it the last time I used it it the x axis was jamming and skipping every now and then if that’s relevant.

I’ll be near it in about 15min and will take some picture of the board.
