Spindle At Speed not working , different units was created by juergen-home
I use version 2.6.3 like you see in the picture attatched.
Stepconf Wizard generated this code with the exeption of my change:
comment out: #net spindle-velocity => near.0.in2
put in : net spindle-fb-filtered-abs-rpm => near.0.in2
Spindle At Speed was not working because it looked like the 2 values for the near function were "spindle-cmd" in rev/min and "spindle-velocity" in rev/s.
To find out If it worked I made the change mentioned above. In this work around don't work for reverse spindle motion because of "abs". Don't know the right value to put in with that filtered function.
Also attached my config files.

I tried this changes, but there came an error message.
I'm not shure if I did it right.
