Removing the XY Belt
Step 1: Release the XY Tensioner
Loosen the XY tensioning screws on the back of the printer with an H2.0 hex wrench.

Step 2: Remove the XY Belt Fixing Blocks
Use the H2.0 hexagon wrench to remove the three screws (M2.5x5) of the belt fixing block and remove the belt from the toolhead.
Do the above for both sides of the toolhead.
Then use a hex wrench to push against the belt holder, pushing it out slightly, and remove the belt holder from the belt. You can then take out the belt.
Note:
To simplify reinstallation, you only need to remove the two belt holders on one side; the other side can stay in place.
If the belt is not held tightly, you can simply push the belt out of the clamp without using a hex wrench.

Step 3: Bonding the Belt
With one end of the old belt freed, you can use the quick-drying glue to carefully align the end of the old belt with the replacement one and glue them together (with belt teeth facing the same direction).
Hold them together carefully until the glue has set.
You can use to the same glueing method for replacing either or both XY belts.

Step 4: Install the Belt Fixing Block
Thread the free end of the new belt through the belt fixing block.
Then attach the belt holder to the end of the new belt, meshing their teeth together.
Pull the belt so the holder is pulled through the belt fixing block and secured back in place.
You can use to the same method for to fix either belt in place.
