Dear All,
I am considering adding encoders and home switches to my Sherline CNC mill.
I see 2 benefits:
1) Being *sure* of not loosing steps (estop, ...)
2) Using (low precision) home switches and the index of the encoder, I get
*excellent* repeatability when homing.
The mill is equipped with

I'm
sure there is a way to solve that problem, but nothing springs to mind
right now.
how about a long limit switch (between 2 encoder indexes), just use a latch
to toggle the state.
to summarize: actual switch AND encoder index - toggle signal for the
latch.
latch output - emc home-sw
