"...modifications and printing the bracket to mount, this thing works like a champ...." Read more

"...It's perfect every time.Absolutely well worth the price." Read more

"...Anyway long story short, this thing is very much worth it...." Read more

"...3. For what it does, it's probably not worth $40. It basically just acts like a button that activates when touching the bed...." Read more

"...Okay, here is the big question. Is the BL-Touch worth the money and the effort to change Marlin? YES!!!..." Read more

32 customers mention11 positive21 negative

Customers are mixed about the sensor. Some mention it's a great sensor, and can't live without it now. It's not an inductive sensor, so you don't have to worry about thick glass. However, others say that it'll not engage at all and won't respond to commands.

"...The probe will not respond to commands at all...." Read more

"...My Original Prusa is great and it comes with a bed-leveling sensor. I tried a knock-off called "3D Touch"...." Read more

"...as I installed the BL touch I noted that the prob would randomly fall out, though, likely due to not having power yet...." Read more

31 customers mention17 positive14 negative

Customers are mixed about the accuracy of the mechanical components. Some mention that it is incredibly accurate, while others say that it's super inaccurate and the least accurate homing device out there. The switch nature of the BLTouch produces slightly less accurate meshes.

"...so long ... but this works beautifully on all bed types, is accurate anywhere on the bed, and is consistent over multiple probings." Read more

"...show while the physical switch nature of the BLtouch produces slightly less accurate meshes, the variance is essentially at such miniscule scales..." Read more

"...run it through it's paces fully but from I've seen so far this seems more accurate and consistent...." Read more

"...and that caused all kinds of problems with this sensor to be super inaccurate...." Read more

Tough to install but worth it in the end.

Tough to install but worth it in the end.
This requires research to install but in the end it's worth it. Once you get your z offset and set it with M851 you are good to go. I installed this on an ender 3 using 1.1.x bugfix firmware of marlin. I printed bed leveling prints found on thingiverse and adjusted z offset until I got the perfect squish and just ran with said z offset. Z-1.6 was my offset that worked the best for me and entered using the M851 command so M851 Z-1.6 then M500 to save then M501 to load and M503 to check.The BLTouch I got was Version 3.0 or 3.1, you just gotta use the bugfix verison of the firmware and then watch tutorials on youtube, but instead of using the firmware they require, just use the bugfix version and change //#define BLTOUCH_V3 to #define BLTOUCH_V3 under configuration.h and leave "#define Z_MIN_PROBE_ENDSTOP_INVERTING false" to false, the way it is, and follow through normally . That's about it. Credit goes to the the anon in the comments of the video I watched.Another thing, make sure you print the right mount for the BLTouch, sometimes the bltouch probe on z is not low enough and that's caused by the mount, so just stack washers where you attach the probe to push it farther down on Z. After that it's smooth sailing, your prints will stick so well that you will need a hammer to remove the parts from the bed if it's done right.I have added some pictures of the prints I have made thus far using the BLTouch without adjusting the bed. Yes it does work if you are willing to spend some time and yes 1M wire length is enough for the ender 3, I had plenty of room, it's just a pain physically install the bltouch, running the wire through the mesh on the bowden tube to your board was a pain. Like I said, not easy to install but was it worth it? For $40 yes it's nice feature to have and you learn how to use your 3d printer more efficiently if you are willing to learn.
