CAIBI project benchmark: Circular Knitic
Prompt version 1.0

Help me build Circular Knitic using the existing creator project at https://github.com/var-mar/circular_knitic. This is a CAIBI benchmark adaptation of the project build brief, not a claim about how the creator used AI.

Project context:
- An open hardware circular knitting machine built with 3D printed parts, laser-cut acrylic, Arduino control and conventional knitting needles.
- Build context: High-quality 3D printed knitting mechanism parts from the published STL set; Laser-cut acrylic plates, primarily 5 mm with 6 mm acrylic specified for the upper gear; Arduino and published control electronics; Stepper motor and drive hardware from the published BOM; MakerBeam structural parts and fasteners from the published BOM; Knitting needles, yarn guides and textile-specific mechanical hardware.
- Where AI helps: Interpret legacy documentation, Arduino changes, Parametric part edits, Pattern and process planning.
- Physical work: Source knitting hardware, Print precisely, Laser cut acrylic, Assemble mechanics, Thread and tune the machine.
- Main limitation: The source is mature rather than current, and it explicitly depends on precise high-quality printing plus large 5mm and 6mm acrylic parts. Mechanical accuracy is the project.

Read the source first. Use its published design, files, dimensions and parts as the baseline; do not redesign it unless a missing detail requires a clearly labelled proposal. If you cannot access a source or verify a revision, say so.

Provide one practical build package:
1. Design and files: explain the source design, link the original editable files, and identify missing files or modifications.
2. Parts and fabrication: give quantities, exact variants and compatibility, plus a cutting or printing list where applicable. Preserve source dimensions; flag anything unconfirmed.
3. UK and US purchasing: direct product links, checked dates, stock, pack sizes, taxes, delivery and regional costs. Mark unverifiable details as unknown; do not invent links, prices or availability.
4. Assembly: an ordered guide covering fabrication, fitting, wiring or software as applicable, setup, checks and troubleshooting.
5. Cost and time: separate parts, fabrication, delivery, hands-on time and machine time, with assumptions and exclusions.
6. Function and ease: a test plan for the project's stated purpose, likely difficulties, required skills and any corrections or limitations.

Keep source facts, your proposals and items needing physical verification distinct. An estimate is not a measured build result. Do not claim to have built or tested hardware. Include failed attempts and omissions. If a section does not apply, say why.

Use the source as accessed during this run and record its revision or access date. The prompt is fixed; the linked source can change.
