99 CENT Ender 3 v2 Filament Sensor - BEST upgrade for summer

99 CENT Ender 3 v2 Filament Sensor - BEST upgrade for summer

You should install a filament sensor on your Ender 3 v2 and this video explains why and how you can do it for under 1 USD worth of parts - and it also has a second function being a filament guide preventing your filament from wearing out your extruder inlet and filament is less prone to break. Enjoy!

Thanks a lot for this - in the end I went with reusing my Ender v2 Z-Stop switch and cable for free - because its now a spare part after I installed the BLtouch (which is a vitual Z-Stop as well). So I just printed a similar filament sensor from thingiverse, cut its cable in halve, made it long enough using a spare wire and plugged the 2-Pin JST connector end into the left 2 pins of the filament connector (right to the green terminal). I use "Professional Firmware for Ender 3 V2/S1 based on Marlin" from mriscoc, went in the menu to Advanced/Filamentsettings and turned "Enable Runout" on, set "Runout Active" to "low" and set "Runout distance" to "0 mm" so it reacts instantly when the z-stop micro switch is released.

For anyone curious I believe you need to get the JST-XH 2.54 connectors. Learn from my mistake.

Make sure you use the NC (Normally Closed) and C (Common) connections. This means that the switch in it's normal state will close the circuit and trigger the run-out sensor. With filament compressing the switch down, opens the circuit.

Nice to know that newer versions of Jyers firmware already support a filament sensor. I wanted to add one on my printer for a while but was too lazy to compile my own firmware. Since I'm running an older build of his firmware I wasn't aware that the newer versions support a sensor natively

[GoblinBlaster]

Welp, bought $25 worth of parts to make the $1 switch but you know what? Always nice to have the extra parts for the future.

Just when I thought I am done with printer upgrades and I can move on to printing something other than upgrades, this comes up.. dang.. too good of an upgrade to pass up..

[valzzu]

ive never ran out if filament in my 2 years and now it happened so time to get a sensor haha

[sebastiaantijbosch]

Fantastic, normally if you try to execute the same as a video it doesn't work. In this case it was truely copy paste and it works. thanks for creating this toturial.

[thaphreak]

THANK YOU!!!

It's near impossible to find anything specifically that says/shows connecting 'G' to 'S' when using a limit switch. 3 thumbs up!

[tsmithdotks]

Looks like a very simple and important upgrade. Thanks for making this tutorial. I'll give it a shot!

[VulcaNtGoF]

A solder free method would be to use 1mm spade connectors on the switch legs. That way, should the switch ever fail (they don't fail a lot, but parts wear out) you could easily plug a new one right in. 🤔

[rickmccaskill]

Thank you. This answered all my questions. Doing update today. Keep great videos like this coming.

This is awesome, though I went with the BigTreeTech smart filament sensor, because it handles detection of jams and clogs, which are the main problems I have. It's rare to accidentally run out of filament. The BTT sensor is amazing, and really not that expensive.

[mikeskitt]

Many thanks for the video. The wiring and settings was really helpful and everything worked on this mod 1st time. The only difference that I used was sliding the sensor wire through the wiring loom; sheath this seemed to make sense to me and only meant snipping and replacing 2 zip ties.

[rodneysmith]

Cool! Great video, I appreciate your hard work and dedication to useful and functional gadgets for my printer.

[Razorsedgeartwork]

The linked connector is the wrong size. Other than that and a little tweek to the switch arm it appears to work well.

[VulcaNtGoF]

AWESOMENESS!! I already have everything I need, except for a roller micro switch. I have a regular one I might give a go, until the rollers come in. The link is up to 5.99 for the switches, so I'm gonna try being cheap, first. Haha!

[AndersEinarHilden]

Would it not be better to invert the switch - then broken cable and missing filament, both unwanted errors, would be detected.

[HaiTHaMKoBeIssI]

Great video like usual, well and easy explained. Thank you.

[ronthomas]

Well done and excellent timing, Thank You, Sir.

[knoxieman]

ive some old pla thats a little brittle and occasionally i get a snap, this will save me loads of time, thanks.
