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?

It doesn't have auto squaring, each motor moves independently while homing and you just adjust the home switches to square the gantry.

Pooh! I thought somewhere I'd read that auto-squaring was possible. Perhaps it was in a possible-future-devoplments chat on the CNCDrive blog or similar.

Back when I had microswitches placed where they could get smashed if they failed to operate and the old version 1 of LinuxCNC on my machine I made a micro-adjustable end-stop (OK, it was an M6 bolt in a bit of aluminium angle) for gantry squaring. That dissapeared when I upgraded to proximity sensors. I'll need to to come up with something similarly cunning for the new installation. The present arrangement is far too clunky for easy fine adjustment which is currently tuned to a hair's breadth in the LinuxCNC v2.8 config file. Once it's been made, a properly implemented mechanical adjuster will be quicker to set up anyway.
