feedrate override using rotary momentary switch?

[paulus.v]

Yes that's correct and it's easy. The analog connector provides 10V for the pot and you feed it back into the analog input. The control then overrides feedrate or Spindle speed based on the returning voltage.

I missed the important part, that the pot controls the override not the actual feedrate value, hence the confusion.

routercnc, sorry for hijacking your thread. I'm curious to see what controls you think are important to be put in the front panel.
