ERB - Side-Load-Filament Guide and Sensor Switch
Description
ERB - Side-Load-Filament Guide and Filament Sensor Switch Note: I will UPDATE this post as more information is available. I wanted a "Side Load Filament Switch" and "Filament Guide" for my Ender 3 and CR-10, the following is what I came up with using Fusion 360. I suspect it would work for most Creality 3D Printers, but It has only been installed it on an Ender 3 and CR-10. This should work with newer 3D Printer Software. I am using it with just a battery and buzzer. Advantages: Side Load Filament Very-very Little Drag The switch can be avoided by routing Filament without engaging the switch Required Hardware, or similar: Fender Washer: M3x15mm Hex Socket Screw: M3x16mm Micro Switch - https://www.amazon.com/gp/product/B07PPPZD4R Wheel, U Groove Track Roller - https://www.amazon.com/gp/product/B079GWHLYN Rotate STL as necessary to print Wheel Post UP Print TIme about 1.5 hours The Print Parameters that I used: Layer Height: 0.2mm Perimeters: 3 Top and Bottom Layers: 3 Fill: Triangles at 30% Supports: Print on Platten Only Print Supports at 45 deg Planned Enhancements: Add filament Over Tension monitoring. [EDIT] See: https://www.thingiverse.com/thing:3711900 Depending on your 3D Printer, the hole for the Switch may need to be enlarged (filed),the Wheel post is also snug, it may need to be shaved. My wheel and switch fit very snug. Note: After soldering on wires, the switch should be inserted from the top, very gently pushed down until it is slightly above (0.2mm) of the provided hole. Check Switch with a piece filament for proper operation. Then epoxy the switch in place from the back (around the soldered wires). I use short wires with end connectors to attach to the external monitoring device. --
