This I believe is the one, but I regularly spin it almost 3x faster than
that. Not for hours on end of course but
I am not at the machine right now but if memory serves me right, I used
G10 L20 P1 Z1.588
Ah! I just saw that P0 is for the active coordinate system. Is P optional?

If you use G10 then it will use the current coordinate system.
G10 is almost always the correct in to use for this.
According to https://www.ia.omron.com/product/item/2463/ max RPM for that
model (E6B2-CWZ6C-2000P) is 6000.

My probe is actually a mechanical switch with a touch plate. I use it by

If you want spindle positioning (for more accurate probing of alignment for
tool changes for examples) you'll need the encoder to follow the position at
all speeds. Are there high RPM capable absolute encoders at a reasonable price?

John haha yep I'll not do that.
I'm thinking I'll use a 1mm cutter anyway if the sensors are good enough
for that

How wide a slot do you think they need to read the light through?
If they could read 0.5mm that would be great
But I probably don't need that accuracy.
I just want it as good as I

means 70 KHz signal.
Can you design an inductive sensor that does 70KHz but is also sensitive
enough for near zero RPM? Optical sensors can work up to 1MHz with no
problem as they don't have any inductanve.You can buy a

Probably not, as it will perhaps have more scope to oscillate at 10,000 rpm.

I can laser cut a encoder disc and get some gear sensors.
Max dia of the disc due to size constraints is 150 mm dia
Questions are mainly design ones.
What width of slots do I need in encoder disc?
