New CR-10s Filament Sensor Housing Assembly by DavidAELevy

Last crawled date: 3 years ago

Owning a few Creality CR-10s 3D printers myself, I was not happy with the design of the stock filament runout sensor. The stock sensor would constantly push off the X bar bracket when the filament was retracted and sometimes get stuck holding filament from extruding and causing print failures. So, I designed a new sensor housing from scratch to use the same internal sensor switch PCB and M3 screws.
My design firmly snugs the X bar bracket without getting in the way of the lead screw or extruder assembly or stepper motor. I also made two versions. Both versions have a holder to keep the hot end cable out of the way of the Y bed. One version has a long bottom mount with a bolt hole for the X bar carriage. And the other version (short) is quicker to print without that longer bottom mount. Both versions are designed to mount snuggly to the X bar extruder bracket. Also, I designed the sensor assembly to allow the filament to feed in and retract with minimal resistance via tapering the guide holes to prevent sharp edges for the filament to catch on.
Fair warning, this design can be challenging to print on a stock CR-10 or CR-10s that has not been carefully calibrated and assembled properly.
I recommend printing as high resolution as you can, I print at 60 microns for PLA, for tolerance and cleanliness reasons.
But anything under 200 microns to max of 250 microns should work, depending on your printer's calibration.
