Creality BL Touch V3.1 Auto Bed Leveling Sensor Ender 3 V2 BLTouch Kit Bed Leveling Upgrade Kit for Ender 3 Ender 3 Pro Ender 3 Max Ender 5 Ender 5 Pro CR-10 with 32-Bit V4.2.2/V4.2.7 Board

If you have a 3D printer, BL Touch is a must have. Once you get this thing tuned in, leveling the bed is a piece of cake. Combine this with some of the more advanced bed leveling features and it can even take into account variations in the bed itself on the fly!With that said, keep in mind that this is not a silver bullet. Should still keep a decently level bed. This just keeps you from having to manually level constantly...

Satisfied with product build quality. Cables about .75 meter too short for my larger custom printer travel since length is set to standard Creality printer model. Looking to locate or fabricate longer custom extension cables that will reach from print head to control board to complete installation.

We ordered this to go on our new Ender 3 Pro that we had just gotten and put together. We immediately installed it and I regret it. The sensor on this thing doesn't always work and failed about 3 times during a 4 hour period before we took it off and packed it back up the return. It didn't sense that it was touching the bed even though the sensor was lit up causing the hot end to dig into the bed and damage it multiple times. This happened randomly when just having it home. Save yourself the trouble and just do your own leveling....found it to be much easier and more reliable.

I only installed this last week, and it's crashed my printer at least 5 times. It works a few times, then it fails, and when it fails, it buries the hot end in the bed. I see advice online like, "it can get jammed with filament, pull it out and push it back a few times." It isn't jammed with filament, it's just a piece of garbage.I'm switching back to simple z-axis limiit switch. This made no improvement in print quality, and I'm just hoping that it didn't do any permanent damage.

Wasn’t sure if this would work with CR 10 pro v2. It screwed in and was plug and play. Took about 5 minutes to hook up and worked right away. I had broken a wire on the one that had came on my printer originally. This was totally my fault and this replacement work perfect.
