Do:

  1. If the inserts went in during the Ch 00 pass, verify them. Otherwise set all four flush with the plastic, square to the face.
  2. Press the two M3 nuts into their pockets in the right carriage half.

Check

Inserts flush and square; nuts fully seated with no gap behind them; an M3 screw starts by hand in every insert.

What you're looking at

A heat-set insert is a knurled brass sleeve melted into the plastic so a steel screw has metal threads to bite into. Four go in here: one per X carriage half, two in the probe retainer bracket. The halves are a handed pair.

Caution

Rev D+ / LDO: "If you are building Clockwork 2 double-check that you have the correct X-Carriage and follow the instructions in the Stealthburner manual." For this kit that is the pair x_frame_V2TR_MGN12_left / x_frame_V2TR_MGN12_right — the R2 / Clockwork-2 halves, not the Afterburner ones. Confirm the filenames against what you actually printed before the belts go in. src (p.129–130)
