You probably want to find the arc center first.

Or, can you just let EMC check it for you?
If you set the work envelope of your machine correctly,
EMC will tell you if there are problems.
Program exceeds machine limits
Program exceed machine (max/min) on axis (X/Y/Z/A/B/C/U/V/W)
[ Run Anyway ] [ Cancel ]
And if you're using Axis
EMC only checks if the endpoints are outside the work envelope, not
intermediary points on the arc.
You can still load the program and look outside the bounds (if set up
properly you see the extent of travel in the preview).

You can start with:
1) disabling the hyperthreading and
2) dedicating one of Atom's cores to EMC (and other RTAI functions) by
adding isolcpus=1 to grub
Unfortunately I cannot explain in more detail, how exactly to do it,
so I can only advice asking uncle google.

Hi,

Look around in your junk box to see if you have any 120 ac to low
voltage ac charging transformers for your battery powered drills,
saws, garden clippers etc. The secondary voltage isn't an issue as
you are looking at phase BUT.. make sure they are AC secondary of course.

Thanks Peter, Roland, Rafael, Jon.
Kim's first answer is on the right track for me. I'm calculating all

at a time. So I can't use the built-in viewer to know. Basically I
need a formula that will tell me if the arc will go out of bounds

I'm controlling axis via emcrsh. It is not uncommon for me to rack up
hundreds of G1 moves (as well as many more G0) throughout a session.

it has been going
