I run a 1000ppr encoder normally on the CNC mills as they run up to 10 k
rpm and max count rates get a bit crazy over that.
On the CNC lathe 3000 rpm max I have a 2500ppr encoder.
Both option work perfectly with rigid tapping.
I have never used a floating tap holder ( just straight in a normal c

I've been asked how many lines an encoder on the spindle should have for
LinuxCNC. I have a disk I made with 60 slots and IIRC someone else on this
forum uses a gear tooth sensor. So a 400 or 600 line encoder isn't really
required but likely there is a point where extra lines don't make any
