1. Machine Will Not Turn On
The Problem: No Power Response
Nothing is more frustrating than pressing the start button of your laser cutting machine and getting no reaction. This issue often stems from basic power or safety-related disruptions, not complex mechanical failures.
The Quick Fix:
- Check the **main power switch**.
- Inspect the **emergency stop button**.
- Verify that all **safety doors** are closed.
2. Bad Cut Quality (Slag/Burrs on Edges)
The Problem: Dirty, Uneven Cut Edges
If your laser-cut parts have slag or burrs along the edges, it requires extra post-processing work.
The Quick Fix:
- **Adjust the focus height**.
- **Increase assist gas pressure**.
3. Laser Beam Power is Low
The Problem: Slow Cutting or Incomplete Penetration
If your laser cutting machine is taking longer than usual, the laser beam power is likely reduced.
The Quick Fix:
- Clean the **protective lens**.
4. Chiller Alarm is On
The Problem: Overheating Risk
If the chiller alarm sounds, the water temperature is too high.
The Quick Fix:
- Check the **chiller water tank level**.
- Check the **shop temperature**.
5. Shapes Are Not Perfect (e.g., Circles Look Like Ovals)
The Problem: Distorted Cuts
If your shapes are uneven, the machine’s movement system is out of alignment.
The Quick Fix:
- Inspect the **drive belts**.
6. Program Stops Running Mid-Job
The Problem: Data Loss or Interruption
A program stopping halfway through a large cut leads to wasted material and time.
The Quick Fix:
- Check the **data cable**.
