Hi guys, I'm completely new with lasers, and unfortunately I'm experiencing a problem with my machine.
I made some tests engraving vinil, and found a setting that seems ok.
But sometimes I'm experimenting inconsistent engraving, without changing any setting.
Or it engraved ok, or with same settings and same material, just seems not having enough power.
What could it be?
It is a 60 Watt CO2, Chinese.


Software: RDWorks v8
Control Panel RDC644XG


Thank you so much for your help
