I want to send commands between a Duet 2 WiFi and a Duet 3 mini 5+ board, to for example, pause or change the speed on the other board.

Is this possible by simply connecting the RX and TX from the PanelDue ports and send the command with M118 P5?

I noticed today that when the sensor is attached the endstop led gives just a bit of light.

When I connect a photomicrosensor everything works well.

Does anyone have an idea?

In config.g:

M574 X1 Y1 S1
M574 Z1 S0

Board: Duet WiFi 1.02 or later
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)

Hello,

I am trying to connect a NPN, normally open proximity sensor to my Duet 2 Wifi. The operating voltage is 5 to 60 V.

5 V and GND are attached to the always on fan pins and the black wire of the sensor to the "Z STOP" pin.

The sensor is not working and the Z endstop led on the board is on.

How to wire this kind of sensor? I read the Wiki about Connecting a Z probe, but I am trying to use the sensor as endstop.
