Duet 2 Wifi - Filament Sensor

xenon2008

Hello together!

I am currently "rebuilding" my new damaged Sapphire Pro.
I changed the Board to a Duet 2 Wifi, changed cables, Hotend, Fans and so on.

Now i am thinking over to install the Filament Run Out Sensor.
I have the orignal one from Sapphire... A Cheap simple Sensor.

In the Duet Doku i found this here:
https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing

Can somebody tell me or explain me, where i must connect this Sensor and how? (Which pin where..)
I also read in the link above this:
"* Note that filament monitoring in RRF is only active when printing from SD card."*

So if i upload a gcode through the Webinterface and print this... will the Sensor be working or not?

I hope everybody here can understand me, i am a German User and my English Skills are not very well

Kind Regards & a nice Evening

Yes, that would be using the internal SD card to store the gcode file and execute it. The alternative which would not work, would be using a USB sending program like octoprint.

Well you'd need a free endstop pin, probably e0stop. And how you'd configure it would depend on your firmware version.

Okay thanks!

I will have a look at this when i am back at home.
Hope i understand this, how to configure

Hello, i am again,

i have now crimped a cable like this:

Sensor GND => Duet 2 Wifi E0 Stop GND
Sensor Signal => Duet 2 Wifi E0 Stop Signal

and added this to my config.g:
M591 D0 P1 C"e0stop" S1

Then i have restarted my Duet, but i only see 3 Endstops in the Webinterface (XYZ) and no E0 Stop??.
Is this normal or did i make a mistake here?

Would somebody help me please?
Is this so right or wrong?

And must i add something to my Start G-Code in the Slicer?

Thanks & have a nice Evening!

What firmware version are you running?

It won't show up as an endstop. It's a switch that is being monitored, but it's not an endstop in the normal sense.

If you start a print and then remove the filament from the switch does it stop the print?

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1

I did not test this for this moment. because i must first build the printer finish...
But you think thats "normal" and i had configured this right?

I am not sure because i found this here:
https://github.com/Duet3D/DuetWebControl/issues/189

JPluess created this issue in Duet3D/DuetWebControl

closed Filamentsensor #189

Configuration looks ok.
