I have a 30w fiber that is acting up. Maybe 25 hours on this unit total. Turned it on today and found I could not get the focus lasers to converge. So I manually focused the laser by adjusting the laser while on continuous fire and hitting the “sweet spot”. After finding my focus I set my parameters for a deep engraving into aluminum only to find I started losing power approximately 2 seconds after the start of the laser firing. Anyone have any ideas what this could possibly be? Could this be a lightburn issue or it my laser machine the problem? Any help would be SO appreciated!
