Common mistakes¶

Starting the 15.2 h P1 plate late in the day and having it finish unattended overnight with no chance to abort a bad first layer.
Starting B01 on Gate A alone — Gate B's bore caliper is what protects these 22.8 h.
Trying to make four identical sets from two a and two b of each part — the sets are mirrored; the corner bins are not interchangeable.
Assuming the deck-support thickness without measuring the actual panel.
Forcing a tight bearing seat with a press instead of reducing extrusion multiplier for the reprint.

Assembly: Z Drives and Idlers (Ch 02), with B02's accent parts already on the shelf. Printing: B02 — Accent parts (blue), the colour change.
