CR Touch Firmware Download: How to Install and Update Your 3D Printer
If you are a 3D printing enthusiast, you probably know how important it is to have a level bed for your prints. A level bed ensures that your first layer adheres well, your print quality is consistent, and your prints don't warp or fail. However, manually leveling your bed can be a tedious and time-consuming process, especially if you have to do it frequently.
That's why many 3D printer users opt for an automatic bed leveling sensor, such as the CR Touch from Creality. The CR Touch is a smart device that can detect the distance between the nozzle and the bed, and adjust the Z-axis accordingly. This way, you don't have to worry about leveling your bed manually, and you can enjoy a hassle-free printing experience.

But how do you install and update your CR Touch firmware? And what are the benefits of doing so? In this article, we will answer these questions and more. We will show you how to download and install CR Touch firmware for your 3D printer, how to troubleshoot common issues with it, and how to get the most out of it. Let's get started!
How to Download CR Touch Firmware
The first step to installing CR Touch on your 3D printer is to download the correct firmware for it. The firmware is the software that controls how your printer operates, and it needs to be compatible with your printer model and motherboard version. Otherwise, you may encounter errors or damage your printer.
So where can you find the official CR Touch firmware for your printer? The best place to look is on Creality's website, where they provide a page dedicated to firmware downloads for various models of printers and accessories. You can access this page by clicking [here](^1^).
On this page, you will see a list of categories for different types of printers and accessories, such as Ender series, CR series, LD series, BL/CR touch, etc. You will need to find the category that matches your printer model and accessory type. For example, if you have an Ender-3 Pro with a CR touch sensor, you will need to click on "Ender Series" and then "Ender-3 Pro".
Once you click on your printer model, you will see a list of files that are available for download. These files include manuals, videos, slicer software, and firmware. You will need to find the file that corresponds to your motherboard version and hardware configuration. For example, if you have an Ender-3 Pro with a 4.2.2 motherboard and a non-adapter board CR touch sensor, you will need to download the file named " Ender-3 Pro_4.2.2_CR Touch_20210302_V1.0.1.rar". You can check your motherboard version by looking at the label on the board or by checking the firmware version on your printer's LCD screen.
Once you have found the right file, you can click on the download icon to save it to your computer. The file will be in a compressed format, such as .rar or .zip, so you will need to extract it using a software like WinRAR or 7-Zip. After extracting the file, you will see a folder that contains the firmware file, usually with a .bin extension.
The next step is to format your SD card and copy the firmware file to it. You will need a micro SD card that is 8GB or less in size, and formatted to FAT32 file system. You can format your SD card using a software like SD Card Formatter or Windows Disk Management. After formatting your SD card, you will need to copy the firmware file to the root directory of the SD card, without renaming it or putting it in any subfolders.

The final step is to insert the SD card and update the firmware on your printer. You will need to turn off your printer and unplug it from the power source. Then, you will need to insert the SD card into the slot on your printer's motherboard, which is usually located under the printer's base or behind a cover. After inserting the SD card, you will need to plug in your printer and turn it on. The printer will automatically detect the firmware file on the SD card and start updating it. You will see a progress bar on your LCD screen, and when it reaches 100%, the update is complete. You can then remove the SD card and restart your printer.
How to Install CR Touch on Your 3D Printer
Now that you have updated your firmware, you are ready to install CR Touch on your 3D printer. The installation process may vary depending on your printer model and hardware configuration, but in general, you will need the following tools and accessories:
- A CR Touch sensor kit, which includes a sensor, a bracket, a cable, and some screws - A screwdriver - A pair of pliers - A pair of scissors - Some zip ties The first step is to run the wires from the CR Touch sensor to your printer's motherboard. You will need to route the wires along the existing wires of your printer, and secure them with zip ties or clips. You will also need to cut off any excess wire length and strip off some insulation from the ends of the wires.
The next step is to connect the cables from the CR Touch sensor to your printer's motherboard. You will need to locate the Z-endstop connector and the servo connector on your motherboard, and plug in the corresponding cables from the CR Touch sensor. The Z-endstop connector is usually labeled as Z- or Z_MIN, and has two pins. The servo connector is usually labeled as SERVO0 or SERVO1, and has three pins. You will need to match the colors of the wires with the pins, as follows:
Wire Color
Z-endstop Connector
Servo Connector
Black
GND
GND
White
Signal
Signal
Red
-
+5V
The final step is to mount the CR Touch sensor on your printer's hotend assembly. You will need to use the bracket and screws that came with your CR Touch kit, and attach them to your printer's fan shroud or carriage plate. You will also need to adjust the height of the sensor so that it is slightly lower than the nozzle tip, but not touching the bed.
After mounting the sensor, you will need to set the Z-offset and calibrate the bed leveling. The Z-offset is the distance between the nozzle tip and the bed when the sensor triggers, and it needs to be set correctly for accurate bed leveling. You can set the Z-offset using your LCD screen or a software like Pronterface or OctoPrint.
To set the Z-offset using your LCD screen, you will need to follow these steps:
- Go to Control > Motion > Z-offset - Home all axes by selecting Auto Home - Move the nozzle close to the center of the bed by selecting Move Axis > X-axis > 10mm > 110 - Move down until you hear a click from CR Touch by selecting Move Axis > Z-axis > 1mm > -5 - Move up until - Move down slowly until you can barely slide a piece of paper between the nozzle and the bed by selecting Move Axis > Z-axis > 0.1mm > -0.1 - Note the Z-offset value on the LCD screen and write it down - Save the Z-offset value by selecting Store Settings To calibrate the bed leveling using your LCD screen, you will need to follow these steps:
- Go to Control > Bed Leveling - Select Level Bed - Wait for the printer to probe nine points on the bed and adjust the Z-axis accordingly - Select Store Settings Congratulations, you have successfully installed and updated your CR Touch firmware and sensor. You can now enjoy a smooth and accurate bed leveling for your 3D prints.
