It is hard to beat GT2. It is the current state of the art in belt-tooth
profile. (except for the identical G3)
But if you are using a belt, then just buy a $30 Omron encoder. No need to
build one as it would be hard to make a better encoder. I doubt you could
make an encoder as small and
There has been some good info on how to build an encoder on this thread. My
concern is how to couple an encoder to my mill spindle. Due to the mill design
it doesn't seem feasible to attach the encoder directly to the spindle so I
will need to use a belt drive. The spindle runs at up to 10500
