What is CR Touch?
CR Touch is an automatic bed leveling sensor that is compatible with most Creality 3D printers. It works by using an optical sensor to detect the distance between the nozzle and the bed, and then adjusting the Z-axis accordingly. This way, you don't have to manually level the bed every time you print, which can save you time and frustration.
CR Touch has some advantages over other similar sensors, such as:
It is easy to install and use, with plug-and-play functionality and clear instructions.
It has a high precision and sensitivity, with a repeatability of 0.005mm.
It has a durable and reliable design, with a metal pin that can withstand high temperatures and wear.
It has a wide compatibility, with support for various models of Creality 3D printers, such as Ender-3, Ender-3 Pro, Ender-3 V2, Ender-5, Ender-5 Pro, Ender-6, CR-10, CR-10 V2, CR-10 V3, etc.
Why do you need to update the firmware?
The firmware is the software that controls the hardware of your 3D printer. It determines how your printer behaves and responds to commands. To use the CR Touch sensor, you need to update the firmware to enable the auto bed leveling feature and communicate with the sensor. Updating the firmware can also bring you some benefits, such as:
It can improve the performance and stability of your printer, by fixing bugs and adding new features.
It can enhance the safety and security of your printer, by preventing overheating, power surges, or unauthorized access.
It can optimize the print quality and speed, by adjusting the settings and parameters according to your needs.
How to download the firmware?
To download the firmware package for your 3D printer model and motherboard version, you need to follow these steps:
Go to and click on "Download" in the top menu.
Scroll down to find "CR Touch Firmware Version for 32-bit Motherboard" and click on "Download".
You will see a list of different firmware files for different printer models and hardware configurations. Choose the one that matches your printer model, motherboard version, and whether you have an adapter board or not. For example, if you have an Ender-3 V2 with a 4.2.7 motherboard without an adapter board, you should choose "Ender-3 V2 HW4.2.7SW1.0.8CRTouch Filament Europe Multi".
Click on "Download" again and save the zip file to your computer. You will need to unzip it to get the .bin file, which is the firmware file.
How to install the firmware?
To install the firmware on your 32-bit motherboard, you need to follow these steps:
Turn off your 3D printer and unplug the power cord.
Insert a micro SD card into your computer and format it to FAT32.
Copy the .bin file that you downloaded and unzipped to the root directory of the micro SD card. Do not rename the file or put it in a folder.
Eject the micro SD card from your computer and insert it into the slot on the motherboard of your 3D printer. Make sure the card is fully inserted and locked in place.
Plug in the power cord and turn on your 3D printer. The firmware will start to update automatically. You will see a progress bar on the screen. Do not turn off or disconnect your printer during this process.
When the firmware update is complete, you will see a message on the screen saying "Update successful". The printer will reboot and load the new firmware. You can remove the micro SD card from the motherboard.

Make sure your printer is turned on and connected to the CR Touch sensor. You can check the connection by going to "Settings" > "About Printer" > "CR Touch Status". It should say "Connected".
Go to "Settings" > "Leveling" > "Auto Home". The printer will move the nozzle to the home position at the front left corner of the bed.
Go to "Settings" > "Leveling" > "Z Offset". The printer will move the nozzle to the center of the bed. Use a piece of paper to check the distance between the nozzle and the bed. You can adjust the Z offset value by using the knob on the screen. A positive value will raise the nozzle, and a negative value will lower it. The ideal distance is when you feel some resistance when moving the paper under the nozzle.
Go back to "Settings" > "Leveling" > "Auto Leveling". The printer will start to probe 16 points on the bed using the CR Touch sensor. You will see a grid of numbers on the screen, representing the height difference of each point. The numbers should be close to zero, indicating a flat and level bed.
Go back to "Settings" > "Leveling" > "Store Settings". This will save your Z offset and auto leveling data to the printer's memory.
