5.2 Operational Risks
- Production Downtime: Cracked versions are notoriously unstable. They may crash during complex 3D operations or long marking cycles, directly impacting production efficiency.
- Hardware Damage: Maliciously modified software can send incorrect signals to the galvo scanners or laser source. There is a documented risk of physical hardware damage (e.g., over-driving the galvo mirrors) when using unauthorized software builds.
- Malware: Sites claiming to offer free license keys for industrial software are prime vectors for trojans, ransomware, and cryptominers.
- No Support: BJJCZ provides zero technical support for unlicensed software. In an industrial setting, the cost of downtime usually far exceeds the cost of the license.
