Simple Optical Filament Runout Sensor
Description
This Is The Result Of A Weekend Project. It Uses A No-Name Optical Endstop (Like This One Http://Www.Geeetech.Com/Images/V/Geeetech_Img_5412.Jpg) Switch And Just "Guides" The Filament Threw It. Endstop Is Connected To A Rasperry Pi Running Octoprint, Which Is Handing The Correct Parking And Resuming By Using The Filament Sensor Plugin Http://Plugins.Octoprint.Org/Plugins/Filament_Sensor . Works With All 1.75 Mm Filament (You Should Be Able To Drill It Up To Work With 3Mm), Except Transparent Ones. I Maybe Design Another One With A Mechanical Enstop In The Future.
