Hardware Requirements
CR touch is compatible with most Creality 3D printers, such as Ender-3, Ender-5, Ender- 6, CR-10, CR-10S, and more. However, you need to check the model and version of your mainboard to make sure it is compatible with CR touch. You can find this information on the mainboard itself or on the printer's manual.
The mainboards that support CR touch are:
Mainboard Model Mainboard Version --- --- Creality V4.2.2 32-bit Creality V4.2.7 32-bit Creality V1.1.5 8-bit If you have a different mainboard model or version, you might need to upgrade your mainboard or use a different bed leveling system.
Software Requirements
Once you have confirmed that your mainboard is compatible with CR touch, you need to download the firmware files and the slicing software for CR touch.
The firmware files are the software that you need to flash on your mainboard to enable CR touch support. You can find them on Creality's official website or on their GitHub repository. You need to download the firmware file that matches your mainboard model and version, as well as your printer model.
The slicing software is the software that you use to prepare your 3D models for printing. It allows you to adjust various settings, such as print speed, layer height, infill, and more. You also need to use the slicing software to calibrate your CR touch sensor and perform auto bed leveling. The recommended slicing software for CR touch is Creality Slicer, which is based on Cura and has a preset profile for CR touch. You can also use other slicing software, such as Cura, PrusaSlicer, or Simplify3D, but you might need to adjust some settings manually.
How to Install CR Touch on Your 3D Printer
After you have downloaded the firmware files and the slicing software, you are ready to install CR touch on your 3D printer. This involves physically connecting the sensor to your mainboard and mounting it on your printer frame.
Step 1: Insert Connectors into 5 Pin Port
The first step is to insert the connectors of the CR touch cable into the 5 pin port on your mainboard. This port is usually labeled as Z-PROBE or BL-TOUCH on your mainboard. Make sure you insert the connectors in the correct orientation, following the color code of the wires. The color code is:
Wire Color Pin Function --- --- Brown Ground Red +5V Power Yellow PWM Signal Black Z Min Signal White GND Signal If you insert the connectors incorrectly, you might damage your mainboard or your sensor.
Step 2: Install CR Touch on the Rack
The next step is to install CR touch on the rack of your printer. This is where you mount the sensor on the metal bracket that holds it in place. The bracket should be included in the CR touch package, along with some screws and nuts. You need to attach the bracket to the left side of your hotend assembly, using the screws and nuts provided. Make sure you align the sensor with the nozzle, leaving a small gap between them. The gap should be about 8 mm, but you can adjust it later when you calibrate your Z offset.
Step 3: Tie the CR Touch Cable Together with Other Printer Cables
The final step is to tie the CR touch cable together with other printer cables, using some zip ties or cable ties. This is to prevent the cable from getting tangled or interfering with the movement of your printer. You should also make sure that the cable is long enough to reach the full range of motion of your printer, without being too loose or too tight.
How to Flash CR Touch Firmware on Your Mainboard
Now that you have installed CR touch on your printer, you need to flash CR touch firmware on your mainboard. This is how you update your mainboard software with CR touch support, so that it can recognize and communicate with the sensor.
Step 1: Download the Correct Firmware Version for Your Mainboard
The first step is to download the correct firmware version for your mainboard from Creality's website or GitHub repository. You need to choose the firmware file that matches your mainboard model and version, as well as your printer model. For example, if you have a Creality V4.2.7 mainboard and an Ender-3 printer , you need to download the firmware file named Ender-3_V427_CR-Touch_20210603.bin. You can find this file on Creality's website under the Download section, or on their GitHub repository under the Firmware/CR-Touch folder.
Once you have downloaded the firmware file, you need to unzip it if it is compressed. You should end up with a .bin file that contains the firmware code.
Step 2: Copy the Firmware File to an SD Card
The next step is to copy the firmware file to an SD card using a computer. You need to use an SD card that is formatted in FAT32 and has a capacity of 8 GB or less. You also need to make sure that the firmware file is the only file on the SD card, and that it is named as firmware.bin. If there are other files on the SD card, or if the firmware file has a different name, the flashing process might not work.
To copy the firmware file to the SD card, you can use a card reader or a USB adapter that connects your SD card to your computer. You can then use your computer's file manager to drag and drop the firmware file to the SD card. Alternatively, you can use a command line tool or a software application to copy the firmware file to the SD card.
Step 3: Insert the SD Card into Your Mainboard and Power On Your Printer
The final step is to insert the SD card into your mainboard and power on your printer. This will initiate the flashing process, which will overwrite your existing firmware with the new CR touch firmware. You can find the SD card slot on your mainboard, usually near the USB port. Make sure you insert the SD card in the correct orientation, following the label on the mainboard.
Once you have inserted the SD card, you can turn on your printer by plugging in the power cord and flipping the switch. You should see a blue LED light on your mainboard, indicating that the flashing process is in progress. The process should take about 10 seconds, after which your printer will reboot automatically. You can then remove the SD card from your mainboard and check if the flashing was successful.
To check if the flashing was successful, you can use your printer's LCD screen or a computer software to access your printer's settings. You should see a new option for CR touch under the configuration menu, as well as a new version number for your firmware. If you don't see these changes, you might need to repeat the flashing process or troubleshoot your mainboard.
How to Calibrate CR Touch on Your 3D Printer
After you have flashed CR touch firmware on your mainboard, you need to calibrate CR touch on your 3D printer. This involves adjusting the Z offset and performing auto bed leveling with CR touch.
Step 1: Home Your Printer and Move the Nozzle to the Center of the Bed
The first step is to home your printer and move the nozzle to the center of the bed. Homing is a process that moves your printer's axes to their origin points, which are defined by endstops or limit switches. This allows your printer to know its position and coordinate system. Moving the nozzle to the center of the bed is to ensure that the sensor and the nozzle are aligned and can measure the distance to the bed accurately.
You can use your printer's LCD screen or a computer software to home your printer and move the nozzle. To home your printer, you need to select the option for auto home or home all axes, which will move your X, Y, and Z axes to their origin points. To move the nozzle to the center of the bed, you need to select the option for move axis or jog control, which will allow you to manually move your X and Y axes to the middle of the bed. You can also use a ruler or a tape measure to check if the nozzle is at the center of the bed.
Step 2: Adjust the Z Offset Using a Piece of Paper
The next step is to adjust the Z offset using a piece of paper. The Z offset is a value that tells your printer how far the nozzle is from the bed when the sensor triggers. It is important to set the Z offset correctly, as it affects how close or far your first layer is from the bed. If the Z offset is too high, your first layer will be too far from the bed and might not stick properly. If the Z offset is too low, your first layer will be too close to the bed and might cause nozzle clogging or scraping.
To adjust the Z offset, you need to use a piece of paper as a feeler gauge. A piece of paper is about 0.1 mm thick, which is a good starting point for setting the Z offset. You need to place the piece of paper between the nozzle and the bed, and then use your printer's LCD screen or a computer software to fine-tune the Z offset until you feel a slight resistance when you slide the paper. This means that the nozzle is just touching the paper, which is about 0.1 mm above the bed.
To fine-tune the Z offset, you need to select the option for CR touch or Z probe offset under the configuration menu. This will allow you to increase or decrease the Z offset value by small increments, such as 0.01 mm or 0.05 mm. You can also use a dial or a knob on your printer or a mouse wheel on your computer to adjust the Z offset. You should see the nozzle moving up or down as you change the Z offset value. You should also see the current Z offset value displayed on your screen.
Once you have adjusted the Z offset using a piece of paper, you need to test it by printing a test pattern or a calibration cube. You can use your slicing software to generate a test pattern or a calibration cube, and then save it as a G-code file on an SD card or send it directly to your printer via USB cable. You should observe how your first layer looks and feels, and adjust the Z offset accordingly if needed.
Step 3: Save the Z Offset and Perform Auto Bed Leveling
The final step is to save the Z offset and perform auto bed leveling with CR touch. Saving the Z offset is to store the value in your printer's memory, so that you don't have to adjust it every time you print. Performing auto bed leveling is to measure the flatness and unevenness of your bed, and compensate for it during printing. This can help you achieve a more consistent and accurate first layer across the entire bed surface.
To save the Z offset and perform auto bed leveling, you need to use your printer's LCD screen or a computer software. To save the Z offset, you need to select the option for store settings or save to EEPROM under the configuration menu. This will write the Z offset value to your printer's memory, which is a non-volatile storage that retains data even when the power is off. To perform auto bed leveling, you need to select the option for auto home or home all axes, and then select the option for level bed or auto bed leveling under the prepare menu. This will initiate a procedure that moves your nozzle and sensor to different points on your bed, and measures the distance between them. You should see a progress bar or a message on your screen, indicating that the auto bed leveling is in progress. The procedure should take about a few minutes, depending on how many points are probed.
Once you have saved the Z offset and performed auto bed leveling, you need to test it by printing a test pattern or a calibration cube. You can use your slicing software to generate a test pattern or a calibration cube, and then save it as a G-code file on an SD card or send it directly to your printer via USB cable. You should observe how your first layer looks and feels across the entire bed, and adjust the Z offset or perform auto bed leveling again if needed.
