Inspect the Hot End Assembly in the Probe Collar

Wait until all machine components are at room temperature before you continue. Some machine components can be hot if the machine was recently used. Failure to do so can cause injuries.

  1. Make sure that the hot end assembly is tight in the one-piece probe collar. Hold the bottom part of the hot end assembly and do the steps that follow:
    • Lightly try to move the hot end assembly back and forth.
    • Lightly try to move the hot end assembly right to left.
    • Lightly try to turn the hot end assembly clockwise and counter-clockwise.
  2. Make sure that the hot end assembly is tight in the one-piece probe collar.
  3. Do steps 1 and 2 for the adjacent toolhead, if necessary.

Tighten the Hot End Assembly in the One-Piece Probe Collar

Do not tighten the one-piece probe collar set screw too much. This can damage the machine component(s).

  2. Calibrate the Z-axis. Refer to Z-Axis Calibration procedure.
  3. Do steps 1 and 2 for the adjacent toolhead, if necessary.
