1. What Could Go Wrong if You Skip the Check?

Before powering up a long-dormant laser cutter, it's essential to understand the risks:

• 🔥 Optics damage: Dust or moisture buildup can cause laser distortion, potentially burning the lens.

• ⚡ Cooling failure: If water remains in the pump, mold or corrosion may block flow.

• 🚒 Fire risk: Debris in the cutting area can ignite from the laser beam.

• ⚙️ Stuck motors: Dry rails or unlubricated components may seize or grind.

Skipping these checks risks not only expensive repairs but could endanger the safety of your workspace.
