The attached photo shows what's happening when cutting (all the time) and engraving (some of the time). The machine is one of the 100 watt Chinese Orion (OME, OMX) that has worked well for 2 years.
The mirrors have been cleaned and alignment testing is right on center. It's happening on various materials so it's not specific to material. Air assist is on. Can anyone let me know what might be the issue please?
Thanks!
