Hello. Is my laser tube going bad? Two weeks ago I noticed some issues with engraving where the engraving quality wasn’t as sharp as it used to be. So I cleaned the optics according to the instructions in the forum. The issue continued, getting worse. Tried different materials: wood and acrylic, tried the same file as a raster and vector. The problem has gotten worse.
Here is a pic or two of the issue in wood and acrylic. The area within the red outline was done by the Glowforge, both raster and vector. The wood is raster and strength at 100%.
