The micRo v1.2.1 will be delivered fully assembled, wired, programmed, trammed and tested by Robin, Kellie and your's truly.
The micRo desktop manufacturer v1.2.1 will arrive to you with nothing to do but turn it on.
COMPUTER AND MACHINE CONTROLLER INCLUDED
The sexy new bot is all inclusive with custom built and programmed embedded computer featuring:
Super fast booting from SSD,
Embedded Machine Control plus,
Embedded Drivers, Power Supplies and Cabling.
These goodies are contained within the ultra small, ultra portable, uber power-efficient Shuttle KPC:

And for those with a couple more Franklins to spend, you can have it with an embedded touchscreen controller!

These machines will come with our custom software installed; 100% ready to play. Our software includes:
Our "Hardened" EMC2 MC.
G-code shape libraries.
The ability to run the bot by hand or by feeding it Python code.
Sophisticated real-time calibration and monitoring software will also be installed.
The micRo machine controller (MMC) boots and runs incredibly fast from its SSD and RAM-loaded OS. The system is configured to allow "unplugging the OS" without any concern; to shut the system down, just kill the power.
The MMC will allow machine control by USB interface (joystick, pendant, Wiimote), and includes pretty decent CAD, CAM, raster and vector programs for in situ job genesis. Basically, you can't kill it, it runs straight out of the box, and it's got everything you need to get to work.
PS, the system will make a fine net-desktop (Ubuntu), or you could dual-boot to windows possibly saving you the expense of another desktop for your home or office.
USA LINEAR WAYS
Another change you will notice is the switch to USA-made linear ways. Perhaps more interesting is that the ways are ceramic coated hardened 6061 alum! There are numerous benefits here; mainly the precision, which is <.001" over 20 feet! This will also allow us to switch to ptfe dry lube for much cleaner operation and will shave off some 14lbs from micRo's shipping weight.

We also ditched the "trucks" on the gantry's X, opting for a end-supported floating X-shaft that offers us better precision, tighter calibration, and most important will give us "pass-through" milling under the X-ways. This will allow much larger pieces to be continuously milled!
CABLING
They say both God and the Devil are in the details; but God only knows how long and hard I've worked on a cabling solution for the mighty micRo!
Sheesh, I'm sure it looks easy as presented, but this stuff is hard to find! The wire spec alone has been thoroughly consternating; and then the failure of tested materials that couldn't take the real world. BLAH. YET....FINALLY, several critical pieces fell into place, and the job was spec'd out far better than I had originally hoped for. The main advances here are sorting the proper wire for the job, finding connectors that unfailing, have high power ratings and physical securement. Another issue is getting the cables assembled, which Robin and I had woefully resigned ourselves to until I found a supplier of the fittings who can also provide professional cable assembly. The wire, (as far as I can tell from some months of searching) is only available from a single British manufacturer. It is only found by knowing the proper DEF-STAN (??) nomenclature, which I have pray written down somewhere...Anyway, this is a 4-conductor braided wire with tinned copper braided shield, is trussed, is small in diameter and is nominally rated for 2x the power we need.

The terminations are made with these wonderful BNC-esque, DIN-esque (haaaard to find in assembly environment) power connectors. I remembered buying them from Radio Crack when I was like 12; they call them CB mic connectors I think (which is not at all helpful).
These connectors are practically indestructible, and they securely fasten by screwing the plug housing into the jack. This is critical to avoid permanent damage to the drivers, or loss of drive to the motors. Amps hate being disconnected when they are live! This usually "lets the smoke out of the chips".
The "female" and "male" jacks...(these terms are weird for jacks containing a probe with holes in it; I think we should call the plug a "she-male" and the jack a "transvestite").
