It can work with any bed surface type or material.
It can be reused more than 100,000 times.
It has stable quality and long service life.
Compatibility and requirements of Creality CR Touch
The Creality CR Touch is compatible with most FDM 3D printers from Creality that have a 32-bit mainboard. Some of these models are:
Ender 3 V2
Ender 3 Pro
Ender 5 Pro
To check your printer model and mainboard version, you can look at the sticker on the back of the printer or open the printer menu and go to "About Printer". You will see the model name and the mainboard version number. For example, Ender 3 V2 with 4.2.2 mainboard.
The Creality CR Touch also requires a firmware update to work properly. The firmware is the software that controls the printer's functions and settings. You need to download the latest firmware from Creality's website and install it on your printer using a micro SD card. We will explain how to do this in the next section.
How to download and install Creality CR Touch firmware?
Before you can use the Creality CR Touch sensor, you need to update your printer's firmware to enable the auto bed leveling function. This is a simple process that takes only a few minutes. Here are the steps you need to follow:
Step 1: Check your printer model and mainboard version
As we mentioned before, you need to know your printer model and mainboard version to download the correct firmware. You can find this information on the sticker on the back of the printer or in the printer menu under "About Printer". For example, Ender 3 V2 with 4.2.2 mainboard.
Step 2: Download the appropriate firmware from Creality website
Once you know your printer model and mainboard version, you can go to Creality's website and download the firmware that matches your specifications. You can find the firmware files under the "Download" section of each product page. For example, for Ender 3 V2 with 4.2.2 mainboard, you can go to and download the file named "Ender-3 V2_32bit_4.2.2V_Marlin-2.0.1V1.3.1_BLTouch.bin". This is the firmware file that supports the Creality CR Touch sensor.

Step 3: Copy the firmware file to a micro SD card
After you download the firmware file, you need to copy it to a micro SD card that has a capacity of 8GB or less and is formatted in FAT32 file system. You can use any SD card reader or adapter to connect the SD card to your computer and copy the file. Make sure you rename the file to "firmware.bin" before copying it to the SD card. This is important for the printer to recognize and update the firmware.
Step 4: Insert the SD card into the printer and power it on
Once you have copied the firmware file to the SD card, you can insert it into the slot on the mainboard of your printer. Make sure you turn off the printer and unplug the power cord before doing this. Then, plug in the power cord and turn on the printer. You will see a blue LED flashing on the mainboard, indicating that the firmware update is in progress. This may take a few seconds or minutes depending on your printer model.
Step 5: Wait for the firmware update to complete
When the firmware update is complete, you will see a message on your printer screen saying "Firmware Update Done". You can then remove the SD card from the mainboard and restart your printer. You will notice some changes in your printer menu, such as a new option for "Leveling" under "Prepare". This means that your printer is now ready to use with the Creality CR Touch sensor.
How to download and install Creality CR Touch hardware?
Besides updating your printer's firmware, you also need to install the Creality CR Touch hardware on your printer. This involves mounting the sensor on the X-axis carriage, running the wires along the extruder cables, and connecting them to the mainboard and the sensor. This is also a simple process that takes only a few minutes. Here are the steps you need to follow:
Step 1: Turn off the printer and unplug the power cord
Before you start installing the Creality CR Touch hardware, you need to make sure that your printer is turned off and unplugged from the power source. This is to avoid any electric shock or damage to your printer.
Step 2: Mount the CR Touch sensor on the X-axis carriage
The Creality CR Touch sensor comes with a metal bracket that allows you to mount it on the X-axis carriage of your printer. You need to use a hex wrench and some screws to attach the bracket to the carriage. You also need to remove the original Z-axis limit switch from the carriage and replace it with a plastic spacer that comes with the sensor. The spacer will prevent the nozzle from hitting the bed when the sensor is triggered.
Step 3: Run the wires along the extruder cables and secure them with zip ties
The Creality CR Touch sensor has two wires: a black one and a white one. The black wire is for power and signal, and the white wire is for ground. You need to run these wires along the extruder cables and secure them with zip ties. Make sure you leave some slack in the wires to allow for movement of the X-axis carriage.
Step 4: Connect the wires to the mainboard and the CR Touch sensor
The next step is to connect the wires to the mainboard and the CR Touch sensor. You need to open the bottom cover of your printer and locate the mainboard. You will see a port labeled "Z-PROBE" on the mainboard. This is where you need to plug in the black wire of the sensor. The white wire needs to be connected to any ground pin on the mainboard. You can use a dupont connector or a soldering iron to make this connection.
After you connect the wires to the mainboard, you need to connect them to the CR Touch sensor as well. The black wire goes into the port labeled "ZMIN" on the sensor, and the white wire goes into the port labeled "GND" on the sensor. You can use the provided connector to make this connection.
Step 5: Turn on the printer and test the sensor function
The final step is to turn on the printer and test the sensor function. You can do this by going to the printer menu and selecting "Prepare" > "Leveling" > "Auto Home". This will move the nozzle to the h
