3D Printer Out of Filament Sensor with Auto Pause
This is a sensor I designed so that I could use up the "almost empty" rolls of filament that I had lying around without worrying about running out of filament and ruining the print.
Note: This sensor works with 1.75mm filament. Please send me a note if you would like a 3mm version.
For Replicator 1 / Rep 2 / Rep 2x / Duplicator 4 / FlashForge / CTC / PowerSpec 3D / Qidi
Requires Sailfish v7.5 r1129 or later
Fits MightyBoards (FF, CTC, PowerSpec, Wanhao, Replicator, Qidi) and FF Dreamer boards.
Please specify which version you have. Contact me if you are having problems.
CTC, PowerSpec, Wanhao, Replicator, Qidi choose the Replicator or Replicator Dual option.
Tested on MightyBoards version E and later, but if you have an X-min input, it should work.
Also works on Qidi revision A boards.
Easy install! Simply remove the bottom cover of your printer and plug in (on most printers).
Will also fit RAMPS 1.4 boards running Marlin, but these also require a firmware update and may require soldering AUX-2 pins in place. I can help with the firmware update.
FlashForge Dreamer, Replicator 2, Replicator 2x Dual will require soldering pins in place.
Please note that FlashForge has started selling the Dreamer 2 / Dreamer NX as just a "Dreamer" instead of correctly labeling it as a "Dreamer 2". These newer models will not work with this sensor. You need the older model, purchased new in the 2014-2016 date range. Contact me if you have questions.
This kit comes with the following parts
End sensor with cable and connector
Zip ties
Installation instructions
Firmware modification instructions (RAMPS only. Sailfish doesn't require modifications). Note I will modify the firmware for you if you wish.
If you have a Flashforge Dreamer, Replicator 2, or Replicator 2x Dual, the kit also includes headers that must be soldered on to the circuit board. (Must remove the circuit board from the printer for this step). Please be sure you are comfortable doing this.
