Ender 3 V2 Filament Runout Sensor and Guide

prusaprinters

You will need: (See in picture) 1x Microswitch 1x Piece of PTFE tube (3~4cm) 1x Double wire 1x 3pin male connector Optional: You may want to pause the print to put the PTFE tube while it is printing (see inpictures). If you want to print with cap, use the files Ender_3V2-_Runout_Sensor_Base.stl and Ender_3V2-_Runout_Sensor_Cap.stl, if not, use only the file Ender_3V2-_Runout_Sensor.stl. If you use stock firmware, probable you will need to update it (I'm not sure if it really need), I recommend to compile Marlin by yourself or download a pre-configured one, like mriscoc or Jyers. After this, you will be able to active Runout Sensor. To better functionality, cut the PTFE tube like showed in the picture. Wiring: The color doesn't matter, but check if the connector wire and switch wire position are ok. Print Settings Printer Brand: Creality Printer: Ender 3 Resolution: 1.2 Infill: 15% Filament: Generic PLA/PETG/ABS Black Notes: You may need cleaning the piece to fit the base and cap, depending of how much accurate your printer is. It doesn't need screw or nut, the microswitch fits perfect. Category: 3D Printer Parts
