Step 18 — Attaching X Axis Bearing Brace
Place the flat portion of X axis bearing clamp away from the arm of the the X cart. Notice
the orientation of clamp to the extruder cart. The clamp should mimic the shape of the
carriage, stair-stepping to the right.
Secure the X axis bearing clamp to extruder card using M3 25mm screws (x4).
TIP: Tighten each screw evenly a little bit at a time alternating between the 4 screws until
all are tight.
Step 19 — Install X Axis Belt Tensioner
Thread the 500mm belt (longer belt) through the 2 holes in the belt tensioner as shown. Zip
tie close to the tensioner, lastly cut off excess plastic tie.
Place M3 40mm screws (x2) through the matching holes in the extruder carriage and
thread them just slightly into the belt tensioner to get started. Make sure that the nub of the
zip tie is facing down, towards the bottom side of the extruder assembly.
