    • Let the extruder cool down.

    • Place a sheet of paper on the heated bed. Manually lower the X axis until the Hemera nozzle is touching the paper.

    • Make sure the X axis is flat (you can slowly move the Hemera left and right).

    • Loosen the PINDA locking screw and place an object of 1mm thickness under the Pinda (like the middle section of a zip tie).

    • Gently move the PINDA down until it is touching the zip tie.

    • Tighten the PINDA locking screw to secure it in place.

    • Use a plier if it is hard to reach the probe with your fingers during adjustment.

  1. Plugin and turn on the printer. Using the screen menu, move the X axis up until it crashes in to the Z tops. The stepper motors will skip. making a noise - this will not damage the motors.

    • Using the screen menu, move the X axis down until the nozzle is approximately 10mm from the heated bed.

  2. If you have applied tension to the belt, unscrew the belt tensioner on x_end_idler until the belt is relaxed. Loosen the screws which secure the trapezoidal nuts. This is to ensure that the Trapezoidal nuts 'self-centre' on the lead screws. Make sure the trapezoidal nuts are moving freely.

    • Tighten the 4 screws alternately (on both sides). Don't apply any lateral force on the trapezoidal nuts.
