Hello everyone,
I am posting this topic because my machine has been having some realy strange behavior that i cannot explain and that i have tried to troubleshoot with no success.

Eventhough M119 gives me the proper endstop state when i trigger them,
When I home my Y axis, the motors acts as if the endstop was already triggered.

However, when I remove the endstop connector from the DUET 3 board, the endstop act like it is not triggered.

CASE 1

Endstop Connected : YES
Endstop Triggered : No
Endstop Status (M119) : Not triggered
Homing behavior : Acts like its triggered

CASE 2

Endstop Connected : No
Endstop Triggered : NAN
Endstop Status (M119) : Not Triggered
Homing Behavior : acts like its not triggered.

I have the endstop config in my Config.g and they are similar with the X and Z axis where i dont have this probleme.

What I have tested.

Changing the endstop itself
Connecting the endstop to another IO pin

jay_s_uk

sounds like you have normally open endstops.
These can suffer from interference causing them to show as triggered.
We've had a few users on the LPC/STM port with this issue on Ender 5 Y axis endstops.
The cables for those are a 6 core ribbon with both motor and endstop cables and the Y motor move causes interference.

Either change to normally closed if you can or change the wiring to the endstop cable is away from motor cables as much as possible

Try turning on the pull-up resistor on your endstops by adding a "^" to your M574 configuration lines and let us know how that goes.
