Filament Runout Sensor for all Extruders using Bowden as Intake. I Utilize Octoprint to Trigger the Sensor. To Build this Sensor, You Will Need the Following Parts: 2x M2 or M2.5 10mm Bolts and Nuts 1x Cheap Switch (WINOMO Premium-125V AC 5 Ampere SPDT 1NC 1NO Short Straight Pivot Lever Mini Micro Switch - 10 Pack from Concelern) Available on Amazon at https://www.amazon.com/dp/B01LX5I5J2/ 1x Push-Fitting PC4-M6 Update 05 January 2020: This Project is Currently a Work in Progress. Some Users Have Reported False Sensor Readings. Update 06 January 2020: The Distance Between the Switch and Filament Has Been Reduced by 0.25mm. This Should Provide a More Reliable Reading. The Design Has Also Been Refined to Require Less Material for Printing.
