BIGTREETECH BLTouch V3.1 Auto Bed Leveling Sensor Kit+Mount Bracket+1M Extension Cable for Ender 3,Ender 3 Pro/Ender 3S/Ender 5/Ender 5 Pro/CR10 3D Printer with SKR Mini E3 V3.0,Octopus/Manta Board

Works as expected, seems to be more accurate on a magnetic flex plate than my cr touch was. Probably due to plastic tip, which I didn't get extras of in my package. On sprite pro extruder with chcb ot nozzle setup.

I decided to upgrade my Ender 3 printers primarily because I was having filament breakage problems (it was the filament, not the printer). Having to reload the Bowden extruder every time the filament broke prompted me to get a new extruder, which prompted me to worry about burning my house down because temperature runaway. It was a snowball...This BTT BLTouch was one of the upgrades. It was easy to install, and it clearly works as advertised. Insofar as it performs as intended, it earns 5 stars. The fact that I don't really understand its purpose when leveling and tramming the bed isn't terribly difficult doesn't take away from its function.So if you're looking to completely ignore bed levelling and tramming, this will absolutely improve your printing life.In the interest of full disclosure - I also upgraded the main boards to BTT SKR Mini E3 V3 with custom built firmware, so your mileage may very when using the stock Ender 3 man board. In other words, the BLTouch works well with the SKR Mini E3 V3.

I have ordered new probes on several occasions and have not been disappointed by the real BL Touch units. They work every time with minimal wiring issues. I wish there was a clean standard for the color code or pin order for the rest of the probes on the market. Depending on your board you may have/want to crimp different ends on the cables to make setup easier. They include a decent length cable in the box but if you are running a larger printer or one that uses a remote control box, you may need even longer cables.The generic CR Touch probe is ok but it is worth spending a little more for the BL Touch. The quality and documentation make it worth it.

My only complaint about this kit and the reason for 4 stars instead of 5 is that it is not the easiest to install and there is not a clear single source of info on installing it if you are a newbie like I was when I bought it. Now that I know a bit more this would have been an easy install. Functionally this thing is 5 stars all the way.

The cable is only 1m. Which sounds like enough but it's really not. You can't route it with your other cables like that, and it will get in the way or snap if you go the furthest away with your printer. Buy one with a length of at least 1.5m instead.Also, it comes with DuPont connectors and such for the cables. If you plan on using that, which you likely due for most of the newer enders, you will also need a crimp tool. This is sorta more of a feature, as it comes with the more general split option. Just keep this in mind.In conclusion buy one with a length of 1.5m minimum.

Works great on my ender 6 (wire it to main board not sister board) will need extra wire though

I ordered this in early February of 2024 and, coming up on the anniversary of my ordering it, I still haven't managed to get it to work right. There is just so little support for a product like this - unless you've taken your printer apart already and magically know exactly where all the wires on this device should go, do not order it.

I was looking for a sensor to precisely level my Ender 3 printer filament head. I ordered this model and it was the best choice! 👍 After calibration and using it for a while, I can say this is a great sensor, very good investment that I highly recommend. #3DPrinters #Ender3 #SensorLove
