Hi everone, Dean here.
In 2013 I started building this CNC Mill. The project started in 2011. My friend gave me some precision ground Japanese ball screws, on the terms that I wouldnt waste them. So I designed this machine around these screws. It was a challenge because I didnt have much money. That ended up being the coolest part about this machine. It was pieced together from various spare parts, and the rest was fabricated from A36 steel plate. The cast iron base was from a 1970s gear hobbing machine. The cast iron workbed & x-axis dovetail were part of an old milling machine. It is a work of art. The machine is very precise too.
The CNC controls use a BeagleBone Black running BeagleG. I designed a cape for the job. "Optocape" is a photocoupler interface cape with integrated video serializer. It allows the BeagleBone Vsys to have it's own PSU, and multiple other PSU can be integrated for various sub-systems. My machine has 4 power supplies. Below are links to video tour of the control box, and Optocape documentation.

I borrowed some money to manufacture a bunch of Optocapes. They are high quality, hand soldered. If anyone is interested they are for sale on Tindie.

I'd like to promote the new hardware. Let me know if you have any questions.
