Goal

Ship a finishable Guide focused on 3d-printer hardware/workflows, with materials, steps, failure modes, and an optional AI assist note.

Materials / prerequisites

  • List exact boards, sensors, filament, or software versions
  • Link related gear on /gear where relevant
  • Safety notes (mains, batteries, hot ends)

Steps

  1. Baseline: prove power + serial / mechanical free motion
  2. Core feature of this guide
  3. Validation test (what “done” looks like)

Troubleshooting

  • Top 3 failure modes for this build
  • How to measure (multimeter, serial log, calipers)

AI assist

Include a copy-paste prompt that requires assumptions lists and refuses invented part numbers.
