Circuit Principle

The diagram shows the CR Touch sensor connected to a 32-bit mainboard. A 5-pin cable, with wires colored red, yellow, green, blue, and black, links the CR Touch to the Z-Stop connector on the mainboard.

Update Firmware

Note: Each printer model corresponds to a specific CR Touch firmware. Please check Appendix 1 for details.

1. Right-click the mouse to format the SD card. To ensure successful firmware flashing, please format the SD card before proceeding.

   Note: The SD card can only hold one firmware file.

2. Firmware Download: Before downloading, please confirm your printer model, motherboard version, and hardware configuration (whether it comes with a filament sensor or not).

3. Copy the firmware to the SD card.

   Note: The SD card can only hold one firmware file.

4. Insert the SD card.
5. Insert the power cord and press the switch.
6. Wait for the firmware to complete the upgrade (approximately 10 seconds).

Note: Every machine has its own operation interface.

Install CR Touch

1. Insert connectors into the 5 Pin Port on the mainboard.
2. Install the CR Touch onto the rack using 2pcs M3*6 screws.
3. Loosen all fan cover screws, then install the CR Touch rack in the corresponding position with 2pcs M3*8 screws.
4. Tie the CR Touch cable together with other printer cables as shown in the illustration.

Circuit Wiring

Connect the CR Touch and the 32-bit motherboard using the 5-pin cable.

Note: Unplug the cable from the Z endstop/limit switch.

Configuration Steps

1. To Get the Z Offset Value

Operation: Prepare → Auto Home → Move Axis → Move Z. Please stop when the nozzle is about 0.1mm (the height of a sheet of A4 paper) from the printer bed. This value shows the Z offset value.

A close-up view shows the 3D printer nozzle positioned just above the print bed. A sheet of A4 paper is placed between the nozzle and the bed to measure the 0.1mm gap, indicating the correct Z offset height.

2. Input the Z-axis Compensation Value (Z Offset Value)

Record the Z offset value, then follow the steps below and save settings:

Operation: Prepare → Auto home → Control → Bed Leveling → Probe Z offset → Input the Z offset value → Store Settings.

Sequences of printer screen interfaces are shown, guiding the user through menus such as 'Info Screen', 'Prepare', 'Auto Home', 'Control', 'Bed Leveling', 'Probe Z Offset', inputting the value '-0.300', and finally 'Store Settings'.

3. Select Bed Leveling, then Choose Level Bed

Operation: Control → Bed Leveling → Probe Z offset → Store Settings.

Note: Different 3D printers may have different numbers of touching points for automatic leveling. The illustration shows that the Ender-3 has 9 points for leveling.

Printer screen menus are shown leading to 'Bed Leveling' and 'Probe Z Offset', with a final screen showing 'Store Settings'.

4. Model Printing

After the automatic leveling, the user can do a trial print to verify the leveling.

Operation: Print from SD Card → Model Test (Name and file of the testing model shall be prepared by user).

Example: A sequence of printer screens is shown, starting from the main menu to selecting a test file named 'Ender3 Bed Level Test meilanz j-29h-107g.gc'.

Test passed: Leveling is completed, and you can print now.

Test failed: If model printing fails, please fine-tune Probe Z Offset again and save settings until the printing effect is good.

Note: Every machine has its own operation interface.

Software Settings

1. Open Slicer.
2. Navigate to Settings → Printer → Manage Printers.
3. Access Machine Settings.
4. In the Start G-code section, change "G28" to "G28G29".

Visuals include a screenshot of a slicer software's 'Manage Printers' dialog, the 'Machine Settings' window, and the G-code editor where the 'G28' command is replaced with 'G28G29' in the Start G-code section.
