NPN Proximity sensor endstop
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.
How do you have your endstops configured?
What firmware version and Duet board are you using?
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)
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?
