7i76e and opto ancoder TCST2103

lowpass or do not low pass :near.spindle-at-speed.in2 ?

For eventually futur upgrad did you think other opto like TCST2203 or TCST2300 (tiny gap) can be better ? (or other part number know to work beter ?)

I would use the lowpassed version for spindle-at-speed

Really a BIG BIG thanks to PCW and andypugh !

IMO all work like a charm now with the help of lowpass
i have at the end add pid.spindle.feedback to lowpass because in my brain the noise is electric noise and not unstable velocity : i'm not really sure if this is a good idea but it seems to be ok. (maybee need to do the same for spindle.0.speed-in)

PID setting i'm not expert but i think is ok.

Really the 7i83 is near the real value without any pid, with some difficulty at start but i'm very very happy to Mesa product and community support !

Now i think is time to return happily to orient and other stuff (oh i forgot the problem with index pin...)
