Are you using a filament sensor with your duet?

[Loffy770]

Good morning!
I thought I ask here in the forum about peoples experience and solution to filament monitor because last night I ran out of filament on a long print and realise that its time to look in to a filament monitor..

Please share your experience and the solution you implemented on your Duet.

Happy eastern

No one with a filament monitor setup?

Several of us have used the prototype Duet3D rotating magnet filament monitor, and fewer (just Duet3D staff so far) have used the prototype Duet3D laser filament monitor. At least one user has connected a third-party rotating wheel sensor to the Duet.

We are going ahead with the manufacture of a small batch of laser filament monitors for resale, and we are in discussions with a third party about further development of the rotating magnet sensor.

For details of how to use filament monitors/sensors with the Duet, see the description of M591 in the GCodes wiki page. Please use firmware 1.21, because we changed the M591 parameters in that version.

For clarification, we use the term "filament sensor" to mean something that just detects whether filament is present or not, and "filament monitor" to mean something that measures the rate (and preferably also direction) of filament consumption.

I'm using a simple microswitch, similar to this: https://www.thingiverse.com/thing:2010235

With this in my config.g: [c]M581 E1 T1 S0 C1 ; Filament run-out sensor triggers a pause[/c]
And this in my start gcode: [c]M582 T1 ; check if filament is present[/c]

So, if I would start a print without filament, it directly goes to pause. If the filament runs out during a print, it also pauses.

David Im up for a pre order of a few laser sensors if possible.

Simple and easy solution
