Here are the same three photos as on post 141. They're not the best, but you can see the new Y-axis stepper mounted in place, and the way I've mounted VFD, stepper drivers and BOB in the existing rack, reusing the screw connectors and plugs from the existing boards.

As noted before, If I did it again I'd probably use the G540 approach, rather than the separate BOB - although the PMDX board I use does connect to two parallel ports, so I have more inputs available. I'm using these for an MPG, a rotary switch to control the axis being jogged, and a high-low jog speed switch
