STEP 29 Aligning the Y-axis belt
Make sure the belt is placed in the
"axis" of the printer. Both top and
bottom part of the belt should be
parallel (above each other).
To adjust the belt position, release
screws on the pulley, and with
slight movements, proceed until you
reach the best position.
Tighten both screws on the pulley.
STEP 30 Y-belt tensioning
Move the Y-carriage all the way from you.
Using a finger on your left hand push the belt down. Some force should be needed
for bending the belt, BUT don't try to overstretch the belt as you might damage the
printer.
You can change the tension in the belt by adjusting the two screws on the MINI-Y-
plate-front:
Tighten the screw , bring the MINI-Y-belt-idler closer and thus increase the
overall tension.
Release the screw , parts will move apart, the overall tension will decrease.
Use the technique described below to test if the belt is properly stretched.
Use pliers to hold the Y-axis motor shaft.
Move the Y-carriage with your hand towards the Y-axis motor. Don't use excessive
force.
If the belt is stretched properly, you should feel a resistance and the Y-carriage
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.
