2. 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.
3. Malware: Sites claiming to offer free license keys for industrial software are prime vectors for trojans, ransomware, and cryptominers.
4. 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.

1. Back up your dongle's firmware. Some JCZ utilities allow you to dump the dongle's unique ID and parameters. Store this on a secure cloud drive.
2. Use a powered USB hub. Dongles can draw power; an underpowered USB port may cause intermittent disconnections during long marking jobs.
3. Label your dongle. If you have multiple laser machines with different controller boards (e.g., one for fiber, one for CO2), label each dongle clearly.
4. Insure your dongle. If your dongle is lost, stolen, or physically destroyed, replacing it means buying a whole new controller board ($300+). Add it to your equipment insurance policy.
5. Keep the original installer files. JCZ changes their download links frequently. Store a copy of the exact EZCAD3 installer version that works with your dongle on a dedicated USB stick.
