It's arrived!
Funny that it takes DHL 7 days to get the little beastie from one side of the planet to the other and another 7 days to get it from one side of the Bass Strait to the other, but they said delivery would be on April 12th right from day one and it was.

Setup went according to the instructions, my laptop obviously has automatic configuration for the straight/crossover cable issue as I'm using a straight cable for direct communication. It took two attempts at opening CCNC with the licence file installed to get UCCNC to start up not in demo mode and to get the laptop and card talking to each other but all seems fine now.
Tomorrow I will look at configuration of ports, limit switches etc. and how to get auto-squaring on the two-motor X axis working. Once that's all done and looking good I can rip the old parallel card out of the machine controller and fit the shiny new one in it's place. Then I can see what postprocessor to use in CamBam and what improvement in performance the more accurately timed pulse streams from the AXBB-E compared to LinuxCNC will give me. What chance 23m/min rapids instead of the current 9?
