Magnetic Filament Sensor Updates?



  • Any progress updates on this as it seems to have gone quiet? I'm really interested in the mentioned potential for this to provide an automatic linear/non-linear extrustion correction.



  • I'm also interested, I am pretty fast at making the measurements and I like the results and the graphs but it takes a while to make them manually, I would love to have them automated or at least not manual.

    Yes there has been progress. We have prototypes of a new mechanical mechanism and slightly modified electronics to go with it.



  • Thanks for the update, that's great to hear. I'm sure after a careful initial calibration this will make a massive difference to the consistency of the machines.



  • I would assume the Magnetic Sensor will be better in being able to pick up more plastic types, but is there a pros/cons spreadsheet comparing both the laser and magnetic sensors? Would there be any cases where you would want both sensors because of those pros/cons? (not sure if you could use both at the same time)



  • Magnetic sensor: Considerably more reliable/accurate/robust. Also more expensive.



  • Just checking in to see if there are any updates on the magnetic sensors?

    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.
