ESC and motor got here right on time yesterday morning. Hobbyking is awesome.

Assembled everything last night and powered it up. Everything fit on pretty much the first try and no_smoke.exe appears to be functioning.

My wiring inside the stepper carriage is getting embarrassing. I think perhaps if there is ever an M2 version, it should use I2C to interface everything on a little dedicated pcb.

Altered the floating stepper carrier to just attach to the rail carriages instead of using a line to the back side of the drive belt after I snapped two of the 1.7mm nylon lines in a homing mishap. It works pretty much the same and it's simpler, albeit noisier and more load on my carriages, bearings, etc. It will work for now.

I have not implemented I2C communication to the ESC yet in software, so I wired it up using the PWM channel.

Changed the beaglebone to use direct Ethernet instead of going over the emulated USB Ethernet. Some issues disappeared, and everything is faster. I think they were client side issues actually, but fixed is fixed.

My plan to use a defunct router as a wifi bridge was thwarted as neither of my junk wireless routers are flashable with anything useful. Using the USB port on the beaglebone for high traffic things like networking causes issues so I'm hesitant to plug in a wifi adapter.
