Creality Upgraded BLTouch Auto Bed Leveling Sensor Kit for Ender-3/3S,Ender-3 Pro, Ender 5,Ender 5 Plus, CR-10,CR 10S, CR-20, CR-20 Pro 3D Printer

I did have a couple of issues which I spent a lot of time trying to figure out so I’m hoping reading this will help someone else avoid the pain. I ended-up figuring this out myself but I can say that while having trouble the seller was very responsive to emails.1) Note that for the CR-10 s (I have the CR-10 S5) there are different versions of the main board. I have V2.0 and the instruction guide "BLtouch Guidebook-Creality V2.pdf" shows this version well but the supplied 2 wire connector for the endstop has the two wires reversed as can be seen in my photo which captures a small portion of the guide's pg 4 for comparison. The connector is error proofed so it can only be assembled one way. If yours is the same you will need to unpin one end and switch the wires. The end which is wrong is the end inside the controller (board end). With a tiny screw driver you can carefully pry up the plastic retainer and the wire will pull out of the connector with little to no force.2) Once I wired the connections and flashed the firmware my Z axis would not move even when I attempted to control it from the control panel. This took a long time to figure out. The printer has 2 Z axis screws and for some reason I thought the right side 4 pin connector was a second z axis stop. In retrospect I should have caught this but I didn’t and it didn’t become obvious that unplugging that connection was my big issue (I also unplugged it inside the controller as well). As soon as I saw a photo of the board with the connections labelled a light came on. I wish the instructions had cautioned that the right side 4 pin connector is for the Z axis motor and it needs to remain as-is during the conversion.A couple of additional notes:The instruction guide shows the flashing of the firmware through an old version of Cura version 15.04. As I can see you do actually need the old version. I had a new version and the same menus do not exist. Look carefully at the instructions and you will see the old version clearly shown. Also interesting on the next page you need to update the software through Cura but this time they are showing the new version. As far as I can tell you need both versions. That’s not a big deal because they are both free and they are both available but it would be nice to really highlight that in the written portion of the instructions.The bracket supplied is very nice; no need to print one before disabling your printer.The wires supplied for the BLtouch are long enough for the CR-10 S5 which has the tallest Z-Axis. They are even a couple of inches longer than the originals.The BLtouch in my kit was version 3.0 but both 3.0 and 3.1 are shipping.I bought additional mesh wrap but I did find that if you pinch the mesh in one place while feeding a section away from where you are pinching toward the pinch the mesh will grow dramatically in diameter. So provided you can get the connector in the end of the mesh (most difficult part) you can push a lot larger diameter through the mesh than you may think.The extra wires can be fed through the grommet in the back of the controller. The instructions never tell you how to get the wires inside.Once you install the BLtouch I strongly recommend using the Bed Visualizer plug-in in Octoprint. To level my CR-10 needs the right front and back screws to the point they are nearly falling off and the left to be almost as tight as I can get them. Front to back the adjustments are about the same.I’m giving this 4 stars but it could be 5 with a couple of small corrections. The kit does overcome 2 common issues I’ve read about (wiring harness too short/ trouble finding the proper firmware) but to be a true 5 stars the black and white wires need to be corrected and there should be a caution in the instructions making it clear the connector labelled Z on the right side must remain. The supplier was even kind enough to send a new link to updated instructions when the information was changed a few weeks after my purchase. Thank you "Haoun-US"

The BLTouch babe highly recommended by multiple forums. Everyone says it's an easy installation and that they had zero problems. That would have been true for me as well, but my particular unit was overlooked in the QA department and two of the wires were transposed, completely confusing my system and resulting in my inability to deploy or run auto tests.Fortunately, the wiring both for the unit and the Creality 4.2.7 board are highly documented and I was able to figure out the problem on my own... That, and a heads up from another reviewer helped.Now that it's properly installed, I'm getting near-perfect prints and my first layer bed adhesion is spot on.I can't recommend this product enough.

I am a software engineer, I found this very difficult to setup. Not physically, the physical install was a breeze though the documentation on the wiring gets dicey and you need to pay attention for the pin 27 adapter wiring. Use the wiring diagram for matching color to pin. The general assembly diagram had a different scheme.The problem I had was firmware. I have the ender 5 and there was a recommended hex for it, but it didn't work well for me. The bltouch landed off the build plate and the firmware was Marlin 1.1.6 without thermal runaway protection enabled. Nope, had to roll my own as I had already done. However getting the right configuration of BLTouch settings with other Marlin options together to stay within the memory limits of the board took a lot of time and some trial-and-error. I spent nearly 2 days flashing and reflashing until i had a configuration I was happy with. I am printing well now, but know that at least for the Ender 5 you are going to have to get more hands on than the instructions.

Got my first 3D printer (Ender 5 pro) and get tired of trying to level the bed manually. I am a software engineer so setting it up and updating the firmware on the board was a breeze, I can see how someone with a non technical background might find it difficult. The issue is finding the right firmware to flash aside from that it’s an awesome device that will be welcome in future purchases for other printers.

Ordered this item and during installation, I discovered the cables were not compatible with Creality’s Mainboard 4.2.2 (or later). This item has two separate connectors that plug into the Mainboard (one is a three pin flat connector and the second is the same type that would fit your Z-axis limit switch). On 4.2.2 Mainboard’s it should be a single connector. If you have a Mainboard 4.2.2 or later, be sure to order a BLTouch V3 kit and not this one!
