John,
Let me save you some time. Unless you are retiring in the next couple
of years and swearing off everything CNC...convert to LinuxCNC now.
If you are not happy with the performance on the BBB right now. Wait
for a couple of years. It will get there via a different set of
hardware or a different hardware version. Mach3 will not. Mach4
might... but you know more than me about that.
If you want a tool that "just works" yet can be extended "reliably" via
software, LinuxCNC or Machinekit is where it is at.
If you want both Mach3 and LinuxCNC, dual boot your PC.
You won't regret it.

Hi John,
I am surprised that you are still talking about Mach3. � I thought that
Mach3 was suppose to be obsoleted by now
and replaced by Mach4. � What happened?� I've been out of the Mach3 loop
for a while.

Hi Dave,
Although the desire to rant here is really tempting I'll put a gag in my mouth
and tie my typing fingers together. Suffice to say:
I have a Delta 14" BabdSaw from 1939, A South Bend Heavy 10L from 1942, most of
my other wood working tools are all at least 20 years old now. Even the ELS I
designed and use on the SB Lathe is 10 years old.
These are all "_Tools_" not an "_Experience_" like Apple, Microsoft and the
Cell phone companies would like you to believe.
MACH3 runs my CNC Router and can read files from AlibreCAD and AlibreCAM as can
the cheap Arduino based 3D printer attached to a Pi2 which is attached via WiFi
to Octoprint. Both effectively are tools that make parts for my work and my
hobbies.
Since MACH3 with a 1.16GHz Athlon with 1MB memory runs the CNC router and responds to
keyboard arrows almost instantly it's the benchmark for all other CNC systems. Don't
really need a new MACH4 "_Experience_" that is hardware licensed to my PC.
Since I'm space constrained in the workshop I was really hoping I could use a
small processor to run CNC on the mill. That the Beagle can't do this to the
same extent as MACH3 means that I have to consider finding space for a PC. And
if I have to find space for a PC it only makes sense to have the same user
interface I have on my CNC router. Then I can spend more time using the tool
compared to having an experience.
So I keep reminding myself before I fall off that cliff of spending many hours
trying to accomplish something (sadly been there many times) that these are
tools that are supposed to work for me.
John
