3. Y AXLES
1. Position the pulleys on the Y axles so that the long front and back timing belts are positioned in a straight line
above the X axles.
2. Place the two calibration sticks on each side of the right Y axle. Fig. 182.
3. Move the print head towards the right until the set screw of the back pulley (connected to the long back timing belt)
is visible and place the Y print head shaft into the calibration sticks.
Make sure the calibration sticks use the same notch.
4. Tighten the set screw of the back pulley with the 2 mm hex key. Fig. 183.
5. If needed, move the print head slightly to the left or right until the set screw of the front pulley (connected to the
long front timing belt) is visible.
6. Tighten the set screw of the front pulley with the 2 mm hex key. Fig. 184.
7. Check if the pulleys on the left Y axle are still in the correct position and tighten the set screws with the hex key.
Fig. 185.
Check if the head moves smoothly. Move the print head diagonally through the printer, you should not feel any
resistance. If you do, the print head is probably not calibrated correctly. If necessary, repeat the steps above.
