The Pirate Ray

The Pirate Ray is Makerspace Næstved's clean-room project for learning how to interoperate with its laser equipment and, over time, building a safe desktop control application.

Phase 0 focuses on the JPT 100 W E2/M7 MOPA fiber laser with a JCZ/EZCAD2 controller. It is deliberately limited to documentation and offline analysis: no USB capture, framing, machine commands, or laser output.

Repository boundary

This public repository contains source code, plans, decisions, tests, tools, and sanitized research. Raw machine data, serial numbers, LightBurn exports, and third-party material with unclear redistribution rights live in the separate private ThePirateRay-PrivateStash repository.

Start with:

• Project charter
• Data handling policy
• LightBurn collection checklist
• Sanitized machine profile
• 110/300 configuration comparison
• Repository boundary decision

Validation

The repository uses only Python's standard library for Phase 0 tooling:

python -m unittest discover -s tests -v
python scripts/check_public_repo.py .

scripts/materialize_private_drive_files.ps1 is the bounded transport used by the acquisition workflow. It accepts authenticated download references over standard input, rejects path traversal, and verifies byte sizes before files enter PrivateStash. It never prints download credentials.

For non-interactive orchestration it also accepts one UTF-8 JSON request as a Base64 parameter. This prevents shell metacharacters in signed references from being interpreted as commands.

No project license has been selected yet. Until that decision is recorded, the contents are not offered under an open-source license.
