Laser cutter not cutting

Laser Cutter is not cutting well?

If the laser cutter is not cutting through the desired material, try these step:

1. Check if your power, speed, and distance setting is correct for the desired material. Please also pay attention to the thickness. If the material setting is not there, you can calibrate to obtain the setting
2. Check the lens, clean with non-alcohol cleaning solution if dirty
3. Re-calibrate the mirror (this is the most extreme fix that we can currently think of for the machine)
