Magnetic Filament Sensor Updates?
-
We are still testing the new prototypes.
-
Interesting that Prusa has abandoned this whole idea and gone another way. I think they went back to a mechanical switch.
-
Has there been any progress on the sensors? I have seen a few posts regarding the sensors and I believe a beta testers post. Just wondering if there is any news at all on them.

Yes, we expect to offer them for sale in the near future.

Have you received any of the assembled sensor boards yet?I would love to see any pictures you may have laying around.
-
@dc42 Can you please shed some light on how near this "near future" is?
I am eagerly awaiting the public availability of the magnetic sensor, and I'd be glad to support you in testing the current prototype version. -
@themelle, our supplier had some issues with manufacturing the plastic housings. Tony may be able to provide a more recent update.

Hey everyone,
Is there an update on these? I would be keen to get one.
Kind Regards,

Tony may have an update later this week.

Is this the Magnetic Filament Sensor everyone has been waiting for?
https://www.filastruder.com/products/duet-magnetic-filament-monitor?variant=17729483374663I assume it is but haven't seen (just missed it maybe?) any confirmation.
Thanks!

It is but I am not sure whether they were going to do some more work to it before they released it which is why I have not ordered one yet
Kind Regards,

I have seen it on Filastruder for a few weeks now and have also held off. I would really like to know if I am waiting for no good reason... Also, I found it odd it comes pre built. And want to know why they did that. It's just does not seem like them to sell something (to makers) that is already made. I would have expected them to release the STL and I would have printed my own. But instead they used SLS (or similar?) and not FDM to print it themselves.
Just curious... -
@BlueDust they have stated you can do fdm but you need to print at high resolution and requires adjustment to ensure the magnet lines up correctly.

I haven't seen anything about it, but haven't spent more than 15 min looking in the forums this week. If this info is in the documentation page, I haven't read it line by line yet. Just skimmed it to start reviewing the GCODE config for it.. appears to be similar to the laser monitor. I already have a laser monitor and it doesn't look different to setup. -
The reason it comes pre-built is that at present it's difficult to test all the components of the magnetic filament monitor without assembling it. We don't just have to test the electronics, we have to verify that the SLA-printed housing holds the magnet at the correct distance from the sensor.
-
I received my Magnetic Filament Sensor. Haven't installed it just yet, but noticed there is a handwritten number on the PCB board. Is that the Serial Number? Maybe n'th one built?

Pretty neat.
Both were taken from the same gcode and filament.M591 D0
Duet3D laser filament monitor v1 on input 3, disabled, allow 10% to 120%, check every 6.0mm, current pos -5.2, brightness 76, shutter 17, measured min 34% avg 42% max 49% over 5778.8mmM591 D0
Duet3D rotating magnet filament monitor v2 on input 3, disabled, sensitivity 28.40mm/rev, allow 10% to 120%, check every 3.0mm, current pos 62.2, measured sensitivity 25.05mm/rev, min 96% max 107% over 109.1mmHow does the Sensitivity work or, being measured on the magnetic sensor?
