The demands of linuxcnc on the kernel can lead one down some unexplored
garden paths, running into all sorts of "bizarre" issues. The simulator,
which is not complete, will run on a stock kernel. You can download that
and run it on darned near anything except when you need motion control
locked to spindle rpms. That generally rules out thread cutting as that
takes feedback from a running spindle the simulation doesn't have.

I agree Deloptes, debian's newer releases are generally better, if the
ever increasing paranoia can be worked around. The major problems are
with the difficulties in building and installing, a newer, realtime
kernel for machine control usage, when the boot protocol is not grub
like, and none of these modern whiz bang credit card sized offerings use
grub to boot. I have sourced some docs on the u-boot process, intending
to write a script that will install a realtime kernel such as
v4.14.15-rt13 I've built on that rock64 in well under an hour, but I'm
still walking thru the ayufan stretch image trying to discern which of
the 4 paths to a good boot he took thru what at first looks like 4! (16)
ways to do it that Mark Harris actually used. Its getting clearer, and I
am starting to make notes, but I'm at least a weeks worth of days from
starting a script. There's stuff there thats probably GPT/MBR related
but what is it? Gibberish to the untrained eye looking at a hexdump.
That, and fighting with my printer because theres no pdf of this doco,
only html, so I must strip and print the html to get a hard copy that I
then have to read with a magnifying glass by the time I've reduced it to
about 75% to keep the gfx diagrams from being cut off by the right edge
of the paper. By then the text fonts are about 4 points high. Thats a
bit small for 83 yo eyes beginning to have cataracts.
But that is my problem, not this lists.
Thank you Deloptes.
Cheers, Gene Heskett
