STEP 31
Y-axis: Assembling the belt
Bend one end of the belt around M3x10 screw.
Push it in the holder as in the picture. Use an Allen key to push the belt in.
Make sure the bent part and the end are within the width of the printed part.
Teeth on the belt must be facing up!
Tighten the screw until you reach the nut, don't over tighten the screw, you will
deform the belt.
Hold the nut from the other side until the screw reaches its thread.
STEP 32
Y-axis: Assembling the belt
Using M3x10 screw fix the Y-belt-holder to the Y-carriage. Tighten the screw and
ensure the printed part is parallel with the "axis" between the Y-motor and Y-belt-
idler.
Use the hole on the left, see the picture.
Guide the belt along the Y-axis, around the pulley on the Y-motor and back.
Make sure the belt is inside the frame, not under!
Pro tip: Temporarily push the Y-axis motor cable into the bottom of the extrusion. It
will make the assembly easier.
Push the belt through the Y-belt-idler and back to the "center" of the Y-carriage.
