Magnetic Filament Sensor alternatives?
-
Good morning, I'm starting to project the implementation for my printer to print in two colors. Now I use a single original Duet Magnetic FIlament Sensor for my extruder, after the implementation I'd need two of them. At now the device is out of stock all over the world so I want to ask if there's an alternative to this sensor wich could be capable not only to work as a filament runout sensor (a simple swith would be enough) but as a clog sensor as well..Does it exist something like that? I cannot use the laser sensor because I oftenly use PETG and some transparent filaments....
Thanks

@the_dragonlord you could try the laser filament monitor with the indirect sensor setup - the original thread:
https://forum.duet3d.com/topic/10042/indirect-bearing-laser-filament-monitor-concept/96
I have found it very reliable, spookily accurate for the monitoring of length extruded, and more or less completely filament type independent. -
@adrian52 Thanks but it's a little too expensive and difficult to get all the "external" parts...I think I'll go with two switches as simple filament runout sensors...

@the_dragonlord
The bigtreetech sensor is about US$25. Its not nearly as precise (~7mm) as the more expensive options. I found that it works much better when mounted so the sensor itself cannot move about (e.g. to the printer frame). I use it on my ender 5 and have it mounted before the extruder motor. Not the most optimal - but it gets the job done.

mmhhh interesting... can you give me a link for the sensor please? Are you using it "as is" or have you modded it in some way?

I second , that BTT sensor is working ok.
Gone trough about 3 rolls of filament -

@stuartofmt thanks! If I'm not wrong this works "only" as a runout sensor not as clog sensor too, am I right? In case what's its advantage related to a normal switch? Other thing: in the site it's written it's compatible only with Marlin...what's necessary to do to make it work with RFF?
Thanks!

No it should function similarly to the magnetic sensor, just lower resolution.

wow, excellent....but are the wiring ant the FW configuration the same as the original? I'd need two of them so could I add it to E0 end stop and E1 end stop?

@the_dragonlord This might be one worth considering (specifically with the clog detection requirement)?
NodeDSF - Native Node-Red integration with Duet boards.
BtnCmd - Customise DWC with user defined buttons/layouts/panels (DWC Plugin)
ReleaseMgr - Duet update info inside DWC.

Finally I've solved the problem because I found an original Magnetic Rotating sensor kit without the housing, so I've ordered it and I'll print the housing
