I have a PDF copy of the Fanuc oi-mc manual and I read the section 14 on
tool length compensation and it does not say anything about storing the
actual tool length from zero (home position).It says that all tool
length compensation values are offsets from programmed position to actual.

Hmm probably nobody. Why?
That solution can report percentage of execution. and works only in
stepper sistem. The solution should be steper and servo friendly.
If we want that precision then assuming coherent file we can just
calculate percentage from CurrentLine/TotalLinesInFile*100 %

Hi
My first time here, hope you can assist.
I have a working stepper driven lathe under Mach, but am not happy with
Mach on many levels and use Linux for everything else, so am migrating
to EMC2.
I have all the basic stuff working, but I cannot do any threading.
I have a single pulse from

Well, I guess I will have to try this out.

Would my 4 magnet set-up through a second pickup provide that, if a
timing pulse is required , or is that too coarse?
More pulses is better, but a few inaccurately-times pulses is probably
worse than 1PPR for introducing errors to the spindle velocity
I'd consider buying a real encoder off Ebay or similar.
With a decent encoder, and the software properly setup, threading works
exactly as expected. Just make sure that you don't get an encoder with
too many Pulses per rev if you are strictly using a LPT port to read the
encoder.

I use speed feedback on my lathe, filtered it using existing Hal functions.
On threading my counter gets reset (spindle encoder) and would be an
enormous negative speed, I limited the rate of change of speed to be
