¶ 2. Disassembly Steps:
¶ Step 1: Turn Off the Device
Before replacing the Y-axis pulley, make sure to turn off the device and disconnect the power for safe operation.
¶ Step 2: Remove the Hotbed
① Take off the PEI board on the hotbed and place it aside for later installation.
② Use an S2.5 Allen key to unscrew the 4 screws securing the hotbed.
There are spacers between the hotbed and the hotbed bracket, so be careful not to lose them.
Place the hotbed and the bottom spacers aside for later installation.
Note: Since the hotbed wires are not disconnected, place the hotbed within the movable range.
