Endstop wiring is functional, but not detected by Duet

nsgarde

Having an issue with my endstops on a Duet 3 MB6HC (new board purchased recently). I have switch-type endstops, normally closed. I wired them between the GND and IN pins of io0-2. Using a multimeter, I can confirm that the switches are indeed working, wiring-wise. Duet cannot read them at all. M119 tells me two of them are triggered, but none of them are - when I do actually close them, M119 has no change. There is no indicator on the dashboard either, nor does homing work.
Relevant config (The actual file has dots in it for the pin names, but the forum won't let me post that since this is a new account and it thinks it's a link):

; Endstops
M574 X2 P"io2in" S1 ; configure X axis endstop
M574 Y1 P"io1in" S1 ; configure Y axis endstop
M574 Z2 P"io0in" S1 ; configure Z axis endstop

M119 output:
Endstops - X: at max stop, Y: at min stop, Z: not stopped, Z probe: at min stop

M115 output:
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.5.4 ELECTRONICS: Duet 3 MB6HC v1.02b or later FIRMWARE_DATE: 2024-11-24 10:47:10

Any help appreciated, thank you in advance. This configuration has worked for me before so I am at odds as to why it isn't right now.

I think your pin names are wrong.

There should be a period character before the two in characters - like io2.in.

@fcwilt Yes, I have written them like that in the real config file. This is a new account and the forum thinks that is a website link, so I could not send the post with that.
