Then it come to telephones real buttons are at an advantage then dialing. The
touch screen is however nice for other purposes.

It might also be as simple as company selling BBB employ people to make it work
well on their hardware. I got the impression BBB is good hardware for 3D
printers and similar. For a CNC machine with an computer screen I am however
not sure.

Micro controllers with SPI or UART is the cheap stuff for control of switches
for servo motors. Ether with or without cat is the expensive stuff at least
compared to the cost of a cheap micro controller. One important point is also
communication distances within a CNC machine is usually short.
Same problem as ordinary software except the emergency stop. I expect there
would be big red hard wired button for emergency stop as usual.
The problem solved is demand for GUI is same or at least similar as for other
software.

Greetings all;
I have an impending amanda drive failure, and my browsers are all
suffering from a lack of 32 bit support to boot, so I am finally
considering installing a 64 bit debian jessie.
Can I still run the sim axis version on that? Or better yet, have you

Pololu-style drivers are under $5 from China, I use the 8825
version, good up to about 2 A at modest voltage.
The CRAMPS board (that I make to Charles Steinkuehler's
design) is $79.95, and m

It sounds like it's more fun than practical. My Android phone hardly
works as a phone. I can't imagine using it to control a VMC. I'd like to
see an old 60's TV as a GUI with a re-purposed Calliope used for a
keyboard or similar.

I don't think their immediate focus is lowering cost, but in reorganizing
the system for distributed modularity. The basic BBB implementation
is pretty low cost, though, and is in use by a lot of people for 3d printing.
They have a gui running on Android devices, so you can have a $40 BBB,
a $70

We build and test on arm, but we currently don't produce debian packages.

How have they lowered the cost of the control and GUI hardware?
I'd like to have a machine controller and GUI for less than the cost of
a new low cost x86 PC and display. Is there a working BOM yet for this?

How real time do you want the GUI? Is a few second lag behind the
machines state ok? How about E-stop or Start/Stop from the UI? What's
safe? 1 second max, 10 seconds? If you are milling while at the beach
miles away does it matter? What problem are we solving?

The MachineKit folk are a year or two ahead of you guys
in thinking about the distributed control approach. You
ought to go over to their site and study their roadmap in
detail before spending lots of time reinventing wheels again.
They use zeromq and protobuf for communication between

FYI, the nxgen controller runs around $15K.
