	1x Y-Carriage
	1x Y-Teeth
	2x 3x16 Torx Screw

• Mount the Y-Teeth onto the Y-Carriage with the 2 M3x16 screws.

• Take a good look on the orientation of all parts.

---

3x Ziptie

• Mount the Y-Carriage onto the linear bearings with zipties.

• Mind the orientation of all parts

• Cut off the loose ends of the zipties.

• Check if the Y-Carriage can move smoothly. It should move by gravity if you tilt the Y-Unit.

	1x GT2 Timing Belt 728mm (the short one)
	1x Belt Tensioner

• Put the timing belt over the idler bearing.

---

• Put one end of the timing belt into the Y-Teeth.

---

• Put the timing belt over the motor pulley.

---

• Put the belt tensioner on the belt as shown in the picture above.

• Put the other end of timing belt into the Y-Teeth.

• The tension should not be too loose nor too tight

  • Too loose: you see the belt moving up and down at the idler when you move the Y-Carriage

  • Too tight: the belt makes sound like a guitar string.

• In all cases it is better to have the belt a bit too tight than too loose.

• The belt tensioner should be (almost) straight as shown in the image.

---

• Put the right hand-flange nut 12,5 centimeters from the backplate

• Lock it with the M10 nut, which functions as a counternut.

• The left hand flange-nut will be fixed later.

---

4x Rubber Feet

• Put the rubber feet in the designated slots of the lower corners.
