My mill is equivalent to a Grizzly G3606. From the now defunct House of Tools. They handle the broken parts and assemble and make sure everything is there before I ever saw it. No real complaints but it's not a HAAS. Of course the price was nowhere near that either.
I know for sure that I'm going to have to either rebuild (redesign) the X axis nut or just install ball screws (preferred). The PC, the CNC control software are such a small part of the whole thing. The BeagleBone design is published and can be used in other layouts. Nothing stops someone from producing a more S100 if you will (but smaller cards) system using it as a backbone processor. Although it's video processing is pretty pitiful. The Pi is not public. But again, 1000 hours (about 6 months work). $100 to $150 per hour. Say with all the design work including metalwork etc. that you can create that magic Linux CNC based box for $150,000. The customer base will probably only want to pay $500 at the most for it since you can duplicate what it does with used PCs and some hardware. The motors, couplers, power supplies etc. remain constant regardless of the install. So if you want to make back your investment and earn a living then $150,000 R&D / $500 per unit is 300 units. And even with $500 per unit the end user still has to modify his machine which is where all the work and money is. If the need was there it would already be filled. IMHO.
