Hey guys
I have a spindle encoder I want to set up for my 10000rpm spindle on one of
my cnc Mills

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?

And is bigger dia better for higher resolution?

Also what resolution do I need for good reliable rigid tapping?   I could
probably laser cut a disc 140mm dia with 400 slots 1mm wide each if that
would let the sensors work OK.

But I don't really know what the sensors can pick up.

Anyway if you guys have already done this I would appreciate the advice.

Cheers

Andrew
