Want EMO on mini5+, but doesn't work by official connect.

Nagoya-Kougei

I read the official emergency stop switch settings and connected the B contact switch, but it didn't work when I pressed it.

Firmware version is 3.4.5.
Mini5+ is V1.02

Duet 3: Connect to any available IO connector, between 3.3V and IO_x.in.
https://docs.duet3d.com/User_manual/Connecting_hardware/IO_E_stop

I wrote code in config.g.

;EMS button
M950 J5 C"0.io5.in"
M581 P5 T2 S1 R0

I attached the B-contact emergency stop switch connector to 3.3V and "0.io5.in", but the trigger did not respond when pressed.

When connecting a general end stop, I think that a switch is connected to GND and "0.io5.in", so I connected the emergency switch this way and it worked.

Is my connection wrong? Or is the description on the site incorrect?

I've tried other common mechanical switches with the 3.3 and "ioXX.in", but they don't respond as well.

@Nagoya-Kougei you should connect to IO.in and ground, not 3.3v.
Also, you should use T0 rather than T2

@jay_s_uk

That connection is correct.

As for T2, it's now T2 for testing.
