3. Rotate the Z column assembly clockwise as far as possible
4. Pull down on the right side of the theta belt to remove it from the theta pulley
5. Remove the cartridge guide nearest the theta motor assembly (Panel0 column4) by using a flat head screw driver to release the tab above the guide.
6. Remove the array

13. Remove the theta motor.

Replacement

1. Note the alignment of the encoder to the arrow mark on the base and, using a torx T14 driver, attach the theta motor to the bracket.
2. Using a Torx T15 driver, attach the three screws from the theta motor bracket to the roof.
3. Attach the array and bracket nearest the theta motor assembly.(panel0 column4)
4. Replace the theta belt on the theta pulley. Rotate the pulley to aid replacement
