8.4
Apply tension to the X-axis (14) Synchronous Belt by pulling
or pushing on the (07) X-axis idler pulley as if trying to
remove it from the end of the channel.
While ensuring the belt is seated correctly in the centre on
the idler pulley, apply enough force in order to keep the belt
tight but with a small amount of slack when pressed down
upon, 3-5mm deflection (no more than this) will be enough.
8.5
While still applying adequate tension on the (14)
Synchronous Belt, use a M2.5 Allen Key (hex key) to rotate
the T-slot nuts 90 degrees, making them perpendicular to
the channel and then continuing to tighten so the assembly
is held firmly in place with no movement. Confirm that both
the T-slot nuts remain at 90 degrees to the (18) X-axis profile
once fully tightened in place.
