¶ XY tensioner idler
¶ Tools
H2.0 hex key
¶ Preparation
Power off the printer
¶ Disassembly
Note: The disassembly and assembly steps of the idlers of the two XY tensioners are similar.
¶ Step 1 - Remove the tensioner holder
To remove the tension spring and its holder, use an H2.0 hex key to loosen and remove the two screws that hold them in place.

¶ Step 2 - Loosen the tensioner
Use an H2.0 hex key to loosen the two screws that hold them in place. Once the screws are loosened, the tensioner should be free to be removed.

¶ Step 3 - Remove the idler
To remove the idler and shaft, first use a hex key to push the idler shaft upwards from the bottom. Once the shaft is loosened, you can remove it along with the idler.

¶ Assembly
¶ Step 1 - Attach the washers
To attach the idler, apply grease to one side of the two washers. Then, place the greased sides of the washers onto the idler. This will help to reduce friction and ensure that the idler moves smoothly.
¶ Step 2 - Install the idler
To reinstall the idler, first attach the idler pulley to the idler bracket. Use a hex key to temporarily thread the idler in place to ensure that it is properly aligned with the washers. Once the idler is in place, use the hex key to press the shaft from the top down, making sure to fully seat it in place. This will help to ensure that the idler is securely attached and will function correctly.

¶ Step 3 - Install the tensioner
To reinstall the tensioner assembly, slide it into place and use two screws (with brackets) to hold it in place. Do not tighten the screws completely. Just keep them loose for now. This will allow you to make adjustments to the tensioner as needed.
¶ Step 4 - Install the tensioner holder
To install the tensioner spring and its holder, first place them in the designated area and use two screws to hold them in place. Make sure to tighten the screws securely to ensure that the tensioner spring and holder are securely attached. This will help to ensure that the tensioner functions correctly.

¶ Step 5 - Tension belt
Use a screwdriver to loosen the two screws of the other tensioner. Then, move the toolhead back and forth several times (according to the arrows in the image below) to allow the manual adjustment of tensioning the belts. Once the toolhead has been moved a few times, ensure the toolhead is stopped at the back of the chamber and proceed to tighten the screws on both tensioners. This will help to ensure that the tension is evenly distributed and that the toolhead moves smoothly.
¶ How to verify
Power on the printer, and run the device self-test process. If the self-test passes, the operation is successful.
