Double filament sensor
Description
Filament Sensor Based On Things [Craftbot Filament Sensor](Https://Www.Thingiverse.Com/Thing:2537054) And [Filament Sensor](Https://Www.Thingiverse.Com/Thing:2563347). Thanks To Them ! First Of All, I Didn'T Have Any Tangle Problem Yet With Good Filament Spool. I Just Keep An Eye On The Ending Spool... So Boring, And We Are Always Distracted At This Critical Moment. Last Week, An Unexpected Issue Appeared... Filament Wasn'T Perfectly Round Somewhere In The Spool, I Noticed Oval 1,75 X 2.02Mm Width... This Resulted With An Half "Air Print" And Filament Stuck On The Ptfe Tube (Ptfe Tube From Spool To Direct Extrudeur). [Craftbot Filament Sensor](Https://Www.Thingiverse.Com/Thing:2537054) Show Me The Road But I Had Different End Stop Sensor In Stock : [Example](Https://Www.Aliexpress.Com/Item/Mylb-10-Pcs-Ac-125V-1A-Spdt-1No-1Nc-Momentary-Long-Hinge-Lever-Micro-Switch/32745688469.Html). [Filament Sensor](Https://Www.Thingiverse.Com/Thing:2563347) Gave Me The First Part. I Designed The Second Part To Fit On The First Part And Solder 2 Endstops In Sequence With The First Normalyclosed And The Second Normalyopen (Respectively Bottom And Top Endstop). Now I Have End Filament Sensor And Tangle Filament Sensor (Or Stuck Filament Anywhere ;) ) Just Wire To Raspberry Or Other Board And Configure Software To Pause The Print When Issue Happen. I Use Octoprint With "Filament Sensor Reloaded" Plugin On Gpio24 And Gnd.
