M574 U2 S1 P"!io3.in" ; configure NC-Endstop for U-Axis on low end
Try this:
M574 U2 S1 P"^io3.in"
Printers: a small Utilmaker style, a small CoreXY and a E3D MS/TC setup. Various hotends. Using Duet 3 hardware running 3.4.6

@domenili Please post your firmware version (send M115 and post response), your full config.g (so we can see how the axes are mapped) and the homing file that causes the behaviour (eg homeall.g).
Even though M119 reports "U: at max endstop" when I feed positive into the endstop
Do you mean when you press the endstop switch? Does it report "U: not stopped" when you let go of the endstop?

No. As @dc42 has said many times (eg https://forum.duet3d.com/post/244186)
Remove the ^ characters. Internal pullup resistors should never be enabled on Duet 3 series electronics.

Curious. In that case I'm surprised the firmware doesn't simply ignore it.

It reports "not stopped" when it's not triggered, and "at max enstop when it is". I bought an endstop with an led to verify the right values at sight.

It tried that, but the behaviour was exactly reversed.
m115 FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2020-05-19b2Config and homeU are attached. Afaik the definition of the endstops is made in config and the homes just take the configured pins right? Because I made no changes at all to the home-files since I switched the endstop.

I've re-posted your files using the </> tag.
Notice in your U homing file the G1 commands. Lines 7 and 9 should be G1 H1.

That did the trick!
But can you explain why that is? It was H2 in stall detection and I neither understand why it accepts H1 while unhomed nor why it makes a difference triggering the endstop.
I should have asked earlier. I was working on that for about week!

Well since stall detection involves running to the limit of travel I would guess it seemed to be working because the move eventually stopped on it's own when using H2 as opposed to stopping when the stall was detected with H1.
In either case it would happen at the limit of travel so the "homed" position would be the same.
I don't use stall detection so I am guessing here.
