Creality Ender 5 Filament Runout Sensor

thingiverse

This is a remix with enhancements that drove me batty about the original. This utilizes the stock ender5 endstop switch, I reused my Z axis switch after going to auto bed leveling, you could also buy one if you wanted to keep your standard leveling. Having both Auto bed leveling and filament runout is an advanced thing for the ender platform, either requiring soldering to your original board and using third party firmware or using a different board. The filament will now align with the extruder and will no longer bend between the two. Expanded the screw holes as they were super hard to get the screw started. Instead of using PTFE tube as guides in and out I created extended tubes with funnels to guide the filament in. This follows the design of most commercial versions. Opened up the filament 'tunnel' just a smidgen, this helped alot with friction at least on my printer. Added a cover, I like to have my electronics covered. The cover leaves open the switch lever so you can see your filament. Requirements 2x M3x4 screws (the original screws with your z-stop switch bracket) 2x M3x8 screws (use with t-nuts to hold to frame) 2x M3 T-nuts 2x M3x12 screws (attach the cover)
