Creality CR Touch Auto Bed Leveling Sensor Kit for 3D Printer with Metal Push Pin for Ender 3/Ender 3 V2/Ender 3 Pro/3 Max/Ender 5 pro/CR-10 with 32 Bit V4.2.2/V4.2.7 Mainboard

The CR Touch is an auto-leveling sensor designed to enhance the 3D printing experience, particularly when paired with 3D printers like the Creality Ender series. Here's a review highlighting its key features and benefits: 1. **Auto-Leveling Precision:** The CR Touch excels at its primary function—automatically leveling the 3D printer's build platform. It uses a precise probe to measure multiple points on the bed's surface, ensuring that the nozzle is always at the optimal height. This results in consistent first layers and improved print quality. 2. **Easy Installation:** Installing the CR Touch is relatively straightforward, especially if you follow the manufacturer's instructions or community guides. It's compatible with a variety of 3D printers, including the Creality Ender series, making it a popular choice among users. 3. **Compatibility:** This sensor is compatible with a wide range of 3D printing materials and can be used with both heated and non-heated beds. It's versatile and accommodates various printing requirements. 4. **Reduced Calibration Efforts:** With the CR Touch, manual bed leveling becomes a thing of the past. This not only saves time but also eliminates the frustration of fine-tuning the bed level before every print. 5. **Improved Print Adhesion:** Proper bed leveling enhances the initial layer adhesion, reducing the chances of print failures caused by warped or unlevel surfaces. 6. **Reliability:** Users often report that the CR Touch is reliable and accurate. Once set up correctly, it consistently ensures a leveled bed, reducing the need for frequent adjustments. 7. **Community Support:** The CR Touch benefits from an active and supportive community of users who share tips, settings, and troubleshooting advice. This can be invaluable for those new to auto-leveling systems. 8. **Price:** While it's an additional expense, the CR Touch is generally considered a worthwhile investment due to the time and hassle it saves in the long run. 9. **Longevity:** Many users have reported that the CR Touch is durable and has a long lifespan, making it a cost-effective choice over time. 10. **Print Quality:** The auto-leveling provided by the CR Touch often results in improved print quality, especially for intricate and complex models. It helps prevent issues like uneven layers and adhesion problems. In conclusion, the CR Touch is a valuable addition to a 3D printer, offering precise auto-leveling capabilities that greatly improve the printing experience. While it comes at an extra cost, the time saved and the enhanced print quality make it a worthwhile investment for both beginners and experienced 3D printing enthusiasts.

This is a fantastic upgrade for any Ender that doesn't have one. Granted I have this on four of my six Enders. I go to those four first. The other two don't get used as much just because they don't have it yet. I plan on adding this to the other two soon. I install it, flash the firmware, get the bed reasonably level, then auto level every time. Easy once its installed and I have way fewer issues after the install and calibration. And it is reasonably priced. Lots of videos out there on how to install this.

I can verify that this is compatible with my Ender 3 V3 KE (even though it is not stated anywhere - they only list models that it can be added to, not models for which it is a compatible replacement part). It is a replacement for the CR touch sensor that I stupidly broke by leaving a large print on the bed and initiating Z Homing. This caused the pin on the initial sensor to bend and the machine startup tests would fail since it no longer passed it's test. Without that, it won't print! So, this is an identical part, just take the broken one off and replace it with this one. First i placed a magazine on the print bed - in case I dropped anything I didn't want it to scratch the hot plate. It's a little tricky unplugging the wire harness from the old one. I used a small flat-head screwdriver to gently work one side up and then the other until it popped off .. then there was still a little bit of glue that didn't want to let go ... I used a utility knife to carefully cut that, being sure to keep the blade pointed AWAY from the wires. After that .. nothing left to do - since it is a replacement, there is no need to go through modifying the firmware - that's stuff is already in place. I did take it through it's initial calibration steps again before printing. My printer went from dead to alive in just a few minutes <insert maniacal laugh>

This is a difficult product to review. The hardware itself is fantastic. 5/5 stars. I worry that the ribbon cable from the sensor to the motherboard is a bit flimsy and hangs precariously close to the Y-motor, but some simple cable management should mitigate that. That said, the firmware implementation by Creality is just abysmal. Depending on which of Creality's three different websites I checked, I found no fewer than three different firmware editions that appeared to be correct for my Ender 3. The first two bricked the machine, to the point it wouldn't boot. The third would boot, but left the screen scrambled. As of January 1, 2023, there appears to be no official working Ender 3 firmware support for the CR Touch. I finally stumbled upon the 3D Printscape website and YouTube videos. This guy is an absolute godsend. He has diagnosed the problem with the current firmware and re-compiled a working version. If you have the scrambled screen issue, I would suggest searching for "cr touch firmware scrambled screen" and working through his library of videos on the process. Installation is not difficult at all if you can find good instructions. Unfortunately, that is somewhat out of Comgrow's hands. Comgrow can't point to a specific firmware, as Creality could upgrade firmware at any minute rendering their recommendation obsolete. To their credit, Comgrow support did try to assist with the issue. I just found 3D Printscape before they were able to solve it. Unless Creality gets their act together, successful installation is a matter of good searching skills and a bit of luck!

I don't even think about leveling the bed anymore. Just get this and some upgraded bed springs and it prints great every time. Really easy to setup with the silent mainboard and correct firmware. Ignore the clogged nozzle, I didn't tighten it down good enough

This sensor does not work with the 4.2.7 mainboard and should not be advertised that it does. There is no CR Touch firmware released by Creality that facilitates using this sensor with the silent board. I tried to get the CR Touch working and failed for two months. I had a working CR Touch with a 4.2.2 mainboard in an Ender 5 pro, but I upgraded to the supposedly compatible 4.2.7 mainboard. To my dismay, the only version of firmware I could find from Creality absolutely did not work. Next I ordered a replacement CR touch device as well as a replacement 4.2.7 mainboard. The results were the same. I even tried using custom firmware to no avail. It's abundantly clear a working Creality firmware version doesn't exist for the component they advertise compatibility for. Unless you're experienced in 3D printing and you're highly tech savvy, I'd avoid Creality printers altogether. Customer Support is virtually non-existent and while the hardware is usually decent, the software required to make the printer usable is a crapshoot. In fact, Creality's entire firmware ecosystem feels like an afterthought. If looking for a bed leveling sensor for your Ender printer, go with the BL Touch. The BL Touch has been around longer and is more widely used, which means the firmware actually works (Creality's and other vendors) and there is a much more wide range of support materials, too. I bought a BL Touch and replaced the CR Touch. Ender 5 pro is now working again with the 4.2.7 mainboard, so please stop saying this sensor is compatible with 4.2.7. There is clearly no compatibility here.

This was my first time using a touch probe, and building my own firmware for the ender3. I probably could have used the official build but I decided to go with Marlin. I was still using the stock firmware from 2021-ish so I proceeded to learn how to build Marlin from source for the Ender-3 SE. In my video I’m using bugfix-2.1.x on a v4.2.2 GD board. Setup was a bit of a learning curve but I got through it and the bed tramming + mesh process eventually. First layers are printing great and adhesion is much improved, and I don’t need to baby step z and retram every time I power cycle the printer now 😅

Works so solidly, you will like your printer more than before. Fixes bed leveling issues. Set your z offset, level the bed with a sheet of paper, hit auto level on your printer. Prints work flawlessly now.
