Laser is cutting fine, but the engraving quality is degrading. Mostly the near left side (surprise to me) and the far right side. Last week though the laser did stop firing during a run, but a power off/on took care of the issue. Tube is about 3 years old running each day about 5 hours. Usual cleaning and table leveling shows no problem.
In the past I replaced the tube when it just stopped firing. I am thinking this time to be ahead of the curve and order a tube instead so I have no downtime. Comments?
