4: Wider and uneven
cutting gap:
- Damaged/ dirty
protective lens.
- Clean or replace it.
5: Rough cutting edge
- Adjust speed
- Lower focus position
6: Uneven colour on edges:
- Check nitrogen gas purity
- Check for any leakages into or
out of the air pipes
NB: The parameters for stainless steel also apply to brass and aluminium
alloy, but because of the higher reflection, you might want to lower the speed a
bit on brass that is >3mm.
