Weird dots all over my engraving

  1. Has anyone ever figured out this issue?
  2. We run (3) Gravotech C02 machines all day for 15 years and never seen this. I bought a Boss LS 1420 (more reasonably priced than Gravo) to be a dedicated machine for some of our products but we are dead in the water with it. It’s NOT the material as we have engraved HUNDREDS with the Gravotech CO2 lasers.
  3. Boss hasn’t been super helpful yet…but not throwing them under the bus just yet but I may have to return this machine if they can’t figure it out ASAP. It’s weeks old.
