Spindle as Joint or Spindle

I was going to try the sim_encoder approach this weekend, but I think you just saved me some bother and time.

Thanks!

EDIT: But then maybe not.... humpff...  All this was for spindle orientation, not the same thing as spindle as C axis... My bad.

A C-axis version would look much the same. Just with joint.3.motor-pos-cmd as the control rather than spindle.0.orient-angle (or whatever that pin is, I am in the Apple store killing time
 

Also, there is a HAL component that can create "fake" index for step-dir controlled drives without encoder.

JPL pointed out that thread, too. I reviewed it and it looks perfect. Thanks for writing that.

If you're interested in using andy's code, I've added some notes on using it with MESA boards.
