Filament Sensor Case & Setup Info/Settings
thingiverse
As featured on Chris' Basement on YouTube. Very cool! Thanks for the support! https://www.youtube.com/watch?v=tl4VZ4zlxFQ There's very little information online about how to wire a filament runout sensor correctly on compound motherboards. Schematics are either outdated, non-existent, or don't provide the data you're looking for. So I hope to help by keeping it simple. This applies to motherboards like my OSOYOO MKS Base v1.5 board and my Hictop red MPX .3. Made this to work with regular end-stops micro switches. (This may also work with regular ramp boards, but I don't have one to confirm personally.) Hardware needed: * End-stop microswitch with pigtail connector * Four 3mm x 1.5mm magnets * M3 x 5mm screw * M3 Nut Software side of things: This applies to Marlin! Specifically the latest version as of December 25, 2017 (v1.1.8) (also working on latest bug fix). There are three changes that must take place: (1) Enable filament runout sensor on Config.h (2) Enable advanced pause and adjust values to what you want your machine to do (3) Make sure the right pin is used by firmware The changes are explained in the text file attached. If I paste code here, Thingiverse would make a mess of it. This works even when using Octoprint. Updated August 2, 2017: Uploaded 3mm version as well
