Note that, in some of steps that follow, we are showing a BearExxa (Bear X axis and extruder). The steps are the same for the Prusa or Bondtech extruders.

Remove the steel sheet and place a sheet of paper on your heated bed (for protection). Remove any residual filament from the nozzle.

Center your extruder on the X axis. Move it down by rotating both Z lead screws simultaneously. Move the extruder down until the nozzle is just touching the paper.

Make sure the X axis is level (horizontal). When moving the extruder left and right, across the heated bed, the distance between the nozzle and heated bed should be the same. Adjust the Z lead screws, if required, until this is so.

Stop when the nozzle is just touching the paper.

Place the middle section of a zip tie under the Pinda.

Loosen the M3x10 screw and gently move the PINDA down until it is touching the zip tie.

Tighten the M3x10 screw to secure the PINDA in place.
