Due to the use of two belts on the Y-axis of the Kobra 2 Max machine, if you only need to replace one belt, please refer to the relevant section for the actual situation.
¶ 1. Tools:
S2.0 Allen key
Open-end wrench
Gloves
¶ 2. Disassembly Steps:
¶ Step 1: Trun Off the Device
Before starting the replacement of the Y-axis belt, make sure to find a relatively spacious workbench or desktop for disassembly.
It is crucial to Trun Off the device and disconnect the power to ensure your safety.
PS: It is recommended to wear gloves, as powder generated from belt wear during disassembly or installation may dirty your hands.
¶ Step 2: Remove the Y-axis Tensioners
① Rotate counterclockwise the red knob on each of the two Y-axis belt tensioners to remove them.
② Use the S2.0 Allen key to remove the 2 screws on each side of each tensioner, and remove the tensioner housing for subsequent installation.
¶ Step 3: Remove the Belts
① Move the heated bed to the Y-axis tensioner side to the front.
Use a wrench or other tool to move the left belt buckle on the guide rail to the right and then forward to remove it.
Move the right belt buckle on the guide rail to the left and then forward to remove it.
(The illustration omits the heated bed components for better display.)
② Remove the pulley assembly from the belt and set it aside for subsequent installation.
③ Move the heated bed to the Y-axis motor side to the rear.
Use a wrench or other tool to move the left belt buckle on the guide rail to the right and then backward to remove it.
Move the right belt buckle on the guide rail to the left and then backward to remove it.
(The illustration omits the heated bed components for better display.)
④ Remove the belt from the Y-axis guide rail. If the buckle on the other side interferes with removal, adjust the position of the buckle slightly.
¶ 3. Installation Steps:
¶ Step 1: Install the Belts
① Take out the new belts, first install the belt buckle on the Y-axis motor side of the heated bed, and clip it into the sheet metal groove.
Note:
I. The toothed side of the belt should face the Y-axis guide rail.
II. The illustration omits the heated bed components for better display.

③ Take out the pulley assembly removed earlier, thread the belt buckle in the direction of the Y-axis tensioner through the pulley assembly,
ensuring that the toothed side of the belt matches the gear surface of the pulley assembly.
