Now that I know that you're happy patching pins on the parallel port, lets test the actual machine.

With all cables/ribbons on the Syil in place, from the DB25 on the machine (not the PC!), ground the X-Axis "Step" pin (pin 7 to pin 25). I'm assuming here that the pin is pulled high on the BOB. At the point that you ground the pin 7 you should get a single step on the x-axis. Continually breaking/making that connection should introduce further steps. The machine isn't going to launch itself - just move microscopically in one direction on the X-axis.

If that's the case then I think you need to look at the parallel port set-up.
I thought it mite of been the pc so I got a new one - the pc is new and the problem remains.

I mite wait till tomorrow for that one - most of my gear is on my houseboat. I’m just rummaging around the shed floor atm so mite wait and go get some proper jumper wires and what not from the boat and do it semi properly tomorrow
