AdeV:
Could you hook something like this encoder up to your spindle? It's massively overkill for your needs (up to 10k pulses/rev, up to 10krpm, not sure if you can do both at the same time...), and at 5v it should hook straight into your MCU setup.

PK:
One pulse per rev.
Here's a video of my CNC lathe conversion turning a 1/8" BSPT thread with ...... wait for it...... a one pulse per rev encoder on the spindle...

eskoilola:
PK, I assume You are driving You spindle with a servo or a stepper. Not by the normal 3-phase motor.

PK:
That's just a normal three phase motor, or a single phase, or a large hamster in a running wheel.

One pulse per rev is all you need to cnc turn threads.

I have a party trick (which I can't find video of). 2 start tapered ACME thread. All done with......wait for it......one pulse per rev.
