I'm having problems with the homing for this new config.
It mostly only moves the z axes when I home x and y, but they move correctly when manually jogged. -

@beej when I installed it and configured it the first time I had some odd issues too. But after a cold start, the steppers behaved normal. I guess it's a SPI setup thing running after a reset.

M574 X2 Y2 Z2 S0 ; Set xy end-stops types (S0 is active low, applied to XY)
S0 means active low, so you will indeed need to invert the pin signal.
So your M547 commands need a ! in front of the pin name, like this:
; Endstops M574 X2 S1 P"!xstop" ; configure active-high endstop for high end on X via pin xstop M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin ystop M574 Z2 S1 P"!zstop" ; configure active-high endstop for high end on Z via pin zstop -

awesome that worked It's homing and everything is moving in the right directions.
The steppers are sounding a little grinding, i'm not sure if that's quite the right word.
But they aren't running as smoothly as they have been, would that have to do with the interpolation, or current...? -

That could explain the difference in sound.

So if it's just the motor attached to P6 that sounds rough, this could be the reason. See https://forum.duet3d.com/topic/16124/duet-maesto-stepper-driver-expansion-schematic/24?_=1629705413513 and the following posts for the remedy.
