If the X axis DRO is correct (correct direction for X) you will need to change the analog output polarity
Not sure how this is done with pncconf, in hal its done changing the sign of
hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogoutN-scalemax

(where N is the channel)

The dro is reading backwards, goes down in the pos dirrection, up in the neg dirrection.

In that case reversing either the encoder scale or swapping encoder leads is the solution

How do I swap the encoder scale in Hal

You just make the encoder scale a negative number.
Or a positive one if it is already negative.

Where in the Hal file is it and what does the code look like please.
