Has two rotary encoders. Which I intended to use as a feed/spindle override. Can I use encoder input 3/4?

Does that device have a quadrature output?
It's not clear from the markings.

Yes it is quadrature.

Probably best connected to the 7I77 MPG inputs if you want 1X mode
but will work on regular encoder inputs if it has 5V signals

I have one MPG connected. Are there 3 "MPG" inputs?

No, there are only inputs for two MPGs on the 7I77 field I/O pins

Is it much more complicated to use the encorder inputs?
Where can I find some example of hal config?

No, basically it just means you change the source of the jog count in the hal file.
it does mean you do not have the 1X mode so you will not get one increment
per detent.
Have you considered using a potentiometer instead for the override?
(this has advantages and disadvantages because of it absolute position nature)

I always prefer this for overrides, easy to set just by looking at it.Have you considered using a potentiometer instead for the override?

Got it working with the following code.
Used "ENC1" and Encorder.3.
Also moved the jumper to "Signal ended encoder" on the Mesa 7i77.
