X3 mill with rails, ATC, new motor

[Jonathan]

I got the ATC working this weekend - at least in principle:





I've made quite a few parts for the carousel etc, but they're all quite simple so it didn't take long. There's a few issues I've mentioned in the video - the main things are to add sensors, change the coupling between the carousel and gearbox for something stiffer and check the clamping torque upon the toolholder. It's currently just controlled using a few lines of gcode - the air solenoids are currently controlled from LinuxCNC via relays just using the M64/M65 commands and delays. When I've got time I'll do it properly, so sensors are checked at each stage (using M66) to avoid mishaps.
