Before replacing the X-axis pulley, ensure that the device is turned off, and disconnect the power for safe operation.
① Pull the Z-axis timing belt to raise or lower the print head to the middle position of the Z-axis for subsequent disassembly.
Note: Pulling to the right will lift the print head (direction of the red arrow), pulling to the left will lower the print head (direction of the yellow arrow).
② Use an S2.5 Allen key to unscrew the 4 screws securing the extruder module, and place the extruder aside.
Since the wires and PTFE tube on the extruder are not disconnected, the range of movement will be limited; just make sure 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.
② Use an S2.0 Allen key to unscrew the front and rear 2 screws securing the X-axis belt tensioner and remove the outer shell.
