STEP 52 Testing the X-axis belt
Use the technique described below
to test if the belt is properly
stretched.
Use pliers to hold the X-axis motor
shaft.
Move the extruder towards the X-
axis motor. Don't use excessive
force.
If the belt is stretched properly, you
should feel a resistance and the
extruder won't move at all. If the
belt is too loose, it will deform
(create a "wave") and jump over the
teeth on the pulley.
Belt too loose? Return to step 49
and repeat all steps until now. You
have to rotate the motor and
retighten the belt in the X-carriage.
Shortening the belt length by
moving one or two teeth outside X-
carriage should be enough.
STEP 53 Trimming the X-axis belt
For the following step we recommend getting a white marker, but you can also trim
the belt without it.
Measure the part, which must be trimmed and gently take the end of the belt away,
from the X-carriage, but make sure at least 3-4 teeth are still in the X-carriage, as
you don't want to lose the tension. If possible make a mark, where to cut the belt.
Ensure again your mark is in the correct position and the belt is still stretched.
Using pliers cut the belt and push it inside X-carriage. Use screwdriver or Allen key,
if needed.
