Orbiter Filament Sensor/Clockwork 2 Mod

Açıklama

Summary This is an adaptation of Robert Lorincz's Orbiter Filament sensor that has been modified for use with a Voron Stealthburner/Clockwork 2 extruder setup. Background While preparing to build my new Voron 2.4 I stumbled upon Teaching Tech's video review of the Orbiter Filament Sensor (https://youtu.be/GbFhhh3tSEU) and thought it looked like a fun bit of kit. Knowing that I wanted a filament sensor for my new Voron, I wondered if I could figure out a way to use this filament sensor with a Clockwork 2 extruder and thus this project was born. I researched the original project (https://orbiterprojects.com/orbiter-filament-sensor/), and ordered my kit from one of the many on-line providers. It wasn't long before I realized that the geometry of the board as designed didn't really work with the Clockwork 2 geometry. Obviously the housing wouldn't work, since it's designed to mount to an Orbiter, but the parts on the PCB are mounted in such a way that no matter how you try to orient the PCB, any housing you design will probably interfere with the Clockwork's latching mechanism. After experimenting in CAD and trying out different configurations, I realized that by reversing the orientation of the unload button and the JST connector, I could compact the whole assembly by quite a bit and, along with a minor modification to the Clockwork 2 main housing, get it to fit nicely. Assembly The difficult part of this assembly is relocating the button and the JST connector to the opposite…
