Original Creality Ender 3 V2 Filament Runout Sensor Smart Filament Sensor Break Detection Module Detector for Ender 3 pro Ender 6 CR-10S PRO CR10 V2 V3 Ender3 Max 3D Printer

The sensor is a bit if a hassle to install. It’s not difficult but it does require some disassembly. It took approximately 30 minutes install and reassemble. The firmware was slightly more challenging, at least for me. I used the Marlin firmware from the guy in Australia who does the firmware updates daily. When I first installed the new firmware, I started a test cube. After the BL Touch checked the bed, it went to the left edge of the bed to run the prime line. When it got to the back of the bed it stopped and went into the change filament mode. I fussed with it for three days. Finally I went through the change filament process, resumed the print and it works perfectly. I have been using a PLA + that is brittle and it does break frequently. I’m glad to have the sensor on both of my Enders.

works

the product works well but you have to know how to code to set it up, there are instructions on where to download the firmware from Crealities website but it does not work and they have to start a work order to get you the firmware, it took a few days for myself to learn how to code and after watching a million videos and talking to a lot of people I was able to get it working and it works well. I wish it was just plug-and-play but it is not

Works great, should have bought it sooner. The only issue is if your filament breaks after passing through the sensor.

works as designed sometimes need to slightly bend filament end to get it to go through easy to install if you are use to upgrading your printer components.

I was careful when purchasing the sensor to make sure it would work with my 4.2.2 motherboard. However, after installing the firmware, the SD card stopped working. Now Creality Support is saying that my 4.2.2 motherboard does NOT support the sensor. This sensor takes a LOT of time to install. Two key screws are reversed from what the Creality video indicates. That means even more components must be removed before the sensor can be installed. Update: Finally resolved all issues by buying a bed leveler kit (Creality DOES have firmware that supports by motherboard AND the filament sensor AND the bed leveler kit). Also, I printed a guide off Thingiverse for the filament sensor.

This item is a very nice upgrade it works well when you are doing long prints if your filament breaks it will stop the program until you can fix the break and it will resume resume the print from that spot

As others said, the unit in the filament drive area pretty much has to be disassembled to add this sensor. It was kind of a pain but the good part is is that the plate was a perfect fit for the sensor and the existing filament drive system. It is a nice clean install. I had a very hard time finding the correct firmware for the upgrade and at one point, the machine was completely inoperable due to the wrong firmware. There was an upgrade for the firmware on the main board and for the screen. Finally after several hours of frustration, I got the correct firmware flashed to the mainboard and to the display. Do your homework on this!! The instructions are pretty much useless. I had to watch You Tube videos and go to forums to figure it out. The switch its self had issues as well. As others said, it had a lot of side play making it go off the side of the filament giving false readings. Finally after slightly bending the switch mounts where it was soldered on to the circuit board so the roller on the end of the switch was directly on top of the filament and against the back of the plastic enclosure it worked consistently. After all that, it works really well but man it was a long road to get there!! I think that these printers are best suited to folks that like to tinker with things and have some technical ability. There is really nothing about them that just works out of the box and as far as technical support goes, you are kind of on your own.
