[title] Installing the belts
[* red] Pass the ''belt'' down to the ''stepper motor'' making sure not to twist it.
[* red] Pass the ''belt'' around the ''pulley'' on the ''stepper motor'', making sure the teeth are engaged.
[* red] Continue pulling the ''belt'' up to the carriage.
[* icon_note] It's helpful to secure the carriage to the tower with masking tape so it doesn't move when you pull on the belt.
[* red] Insert the ''belt'' into the slot in the carriage stretching the ''belt'' tight - but you do not need to overdo it. Secure the end of the ''belt'' with a ''Zip Tie'' and clip the ends of the ''belt'' and ''Zip Tie'' as shown in the second photo.
[* red] Look at the third photo, the ''belt'' should be evenly spaced from the tower its entire length. You will probably have to adjust the ''pulley'' position on the ''stepper motor'' shaft to bring it into alignment.
[* red] Loosen the two set screws on the ''pulley'' - you can see the set screws in the first photo. Then move the ''pulley'' on the shaft to bring the ''belt'' into alignment with the tower. Tighten the set screws.
[* icon_reminder] Repeat '''Steps 41''' and '''42''' to install the ''belts'' on the remaining two towers.
