Filament Monitor Beta Overview
-
I see.

Looks great.
But a Filament Diameter Sensor for 1.75mm and 2.85mm/3mm would be awesome.
I know this type of Sensor is (i belive) easyer to get in to everything.
-
I cannot see why this sensor can't-do 3mm, surely its just a case of reorientating the idler so that it sits on the other side of the elastic cam pieces supporting it, so there is enough space for 3mm filament to be inserted.

Yes I have tested the current enclosure with 3mm as well as 1.75mm filament. the elastic springs can be rotated so there is a larger gap.
A filament diameter sensor is a whole different issue though. Just thinking about the elasticity in the system and the delay makes my head hurt.

It's a hard nut to crack, but a genuinely auto-calibrating extruder would give even the Prusa team pause for thought.
-
Is this only intended for run out and stall detection or could I monitor the actual vs commanded extrusion ratio.
Im printing often at the upper limits of what the extruder is willing to push through, so a tool that could confirm and compensate this:

The firmware detects the difference between the commanded extrusion and the amount filament moves (taking into account retraction) any then raises an error and pauses the print if that difference grows out of tolerance.

You would need to calibrate the filament monitor first, so it's chicken and egg. Unless the filament monitor was so accurately made that it needed no calibration.

I agree that the duet filament monitor it isn't going to be the route to achieving this but the general idea of an extruder which always extrudes the right amount of material is definitely a concept worth trying to realise. Otherwise, consumer 3d printers will have to use filament in cartridges, which has a factory determined tolerance for width, roundness etc…
-
Good quality filament already has that.

Hi,
is the magnet filament sensor still in beta testing? If so, is it possible to still participate? If not, then how to purchase the filament monitor? Since I have the "filament stuck" problem with a bunch of our printers, I would be very much interested in testing or using it. Thanks.

@biggsis Its had a redesign and the new design prototypes are on order. I will make a new thread about it once we have an estimated date to release it.
