I'm looking for ideas for the thc comp. If the gain is set high enough
to react to say corrugated stock you get oscillation (overshoot). There
are some pretty smart folks on this mailing list, if I can get some
hints I'll run with it.
The current version in LinuxCNC is:

What is the requirement to be able to import emccanon?
It seems to work in remap code, and in the tests (for example
https://github.com/LinuxCNC/linuxcnc/blob/af15a4d90e1d51d5309db65fe1c9511e486df411/tests/remap/fail/canon_error/remap.py

But if I try "import emccanon" in a GladeVCP handler, it ex
For spindles that don't have control all you need is M3/4 S1.

I have an encoder.
An encoder (at least a single

I kinda think you're going to want that

John, you raise a good point here. The general assumption is that the S
word is a reasonable prediction of spindle speed. What do you think of
having a check at both interp time and runtime? That would cover all cases.
For machines like yours, we could suppress the interp-time error. Is there
an IN
