Before replacing the X-axis pulley, ensure that the device is powered off and disconnected to ensure safe operations.
① Pull the Z-axis synchronous belt to lift or lower the print head to the middle position of the Z-axis for subsequent disassembly.
Note: Pulling to the right raises the print head (red arrow direction), pulling to the left lowers the print head (yellow arrow direction).
② Use the S2.5 Allen key to unscrew the 4 screws securing the print head module and place the print head aside.
As there is no need to disconnect the wires and PTFE tube on the print head, the movement range is limited. Just ensure it is within the active range.
① Rotate the red knob on the X-axis belt tensioner counterclockwise and remove it, placing it aside for later installation.
