Do you have a precision miter saw like this, or similar?

No. And blades for such are mail order only in these parts.
Very thin, fine teeth, minimal set so it cuts a very narrow kerf. As for how
many cuts the blade will last cutting carbon fiber???
Not long. In fact, the thought of cutting with a welded binder strap
whose edge was annointed with a rouge stick crossed my mind, but was
discarded. It has been done though in the Tool and Die shop at Solar
Aircraft in the 1950, to cut titanium when they ran out of band saw
blades, worked surprisingly well in fact. In those days, bandsaws came
with their own blade welder, and steel binder strap was scrap they had
an endless supply of.

Greetings all;
An unusual question. How to cut, neatly, and squarely, a 20mm square
carbon fiber tube to length, say 550mm out of an 800mm tube. I'm making
a linear rail bearing X axis for two of my 3d printers,
I have a die grinder that I can mount in a quick change holder, and a 2"
by 30 thou CBN disk and 1/4" arbor, and a 4 jaw chuck on my Sheldon.
Do I need to print an 18mm square plug to insert into this tubing to
support the 1mm thick tubing walls, or can a relatively light grip be
enough to hold it fixed while I turn slow and cut it off with the CBN
wheel running at about half line voltage in the die grinder?
All I can see in my minds eye is a hugely ragged edge cutting it by hand
with a hacksaw.
Better ideas anybody?
