Hi Matevz.
No, I alreadu have the MPG as you link to.
It's more to control the Feed, Jog, Spindle, MPG-Jog speeds.
The "real" panels have 3-4 smaller knobs for adjusting the override of above speeds.
But I'm unsure if this is done via:
- Rotary encoders (grey-bit) Require 2 inputs, and rather precise in positioning.
- Pot meters ( 0-3.3V) Require only one input, but it "jumps" in the setting, and not easy to get back to precise 0% override.
- Rotary switch (1 pole, 12 posistions) This requires 12 inputs :-/
I was planning on using the Rotary encoder, but i can only find some with 20-24 ppr, which results in 5 turns to get 100% :-/
Any suggestions, perhaps there is a trick to get the analog one not to "jump" in voltage.
Best Regards, Bo Andersen.
