I picked some IP68 connectors for the 4th axis, cabling for the coolant pump and molex connectors for some of the internal hookups. I had to get 50 ft of cable, but I have ambitions of using it in other projects.
Below links to the Allied catalog and/or datasheets in case someone is interested. The SKUs are on the 1st pic

I also got bit and pieces to do a LED thing for the LPT port which shows on/off signals. Doing 2 of those, one to connect at the computer and one to connect at the end of the cable. See 2nd pic for SKUs and this link on how to put it together http://www.epanorama.net/circuits/parallel_output.html
