Problems with new Laser Filament Monitor
-
Something like this
Now I need to think the thing around the concept
-
That Prusa one on Thingy manages with one bearing. And weirdly it seems to read the side of the bearing instead of the circumference. Presumably you will want some kind of weak spring in there somewhere keeping tension on the filament without wearing out the tubing.
-
@3dmntbighker yes... I'll leave the "reading" bearing fixed and the second bearing will press against the filament with some type of spring system - like the one used with bmtech extruders.
-
would lightly sanding the bearing also help with the sensor pickup more light?
-
@nikker Not needed for the sensor as it is perfect for the type of surface the bearing offers. What concerns me is the possibility of the filament slipping the bearing somehow. If this starts happening then the sanding will help.
-
What about some knock off Bondtech gears?

I don't think you want to distort the filament that much before it reaches the real extruder.

good point... I would really like to get a filament sensor. It seems like the magnetic version worked a lot better from what i remember reading however i guess its the laser version that is only available. I have some time to tinker between my current build. I haven't read this whole thread but do we think we can get it to work reliably with some community effort? If so I'll place an order to buy one. My current build has the extruder temporarily mounted on the outside and is wired up and already calibrated so seems like a good time to help? Would be nice if I could contribute to the community after lurking for so long...

Where do I find the STL for the Bondtech? Can't seem to locate it anywhere

@cabal2000 I have recently put a spring loaded version of the indirect monitor housing on thingiverse (3717158). It seems to work well, especially recording total filament use very accurately.
