Even though I don’t use my laser as much as some, it is probably on every 3 days or so for a few hours at a time. After having to pull it apart for repairs the other day I decided to go back to nuts and bolts to clean everything.
Lets just say I was surprised/stunned at how much soot and dust had collected on and around the circuit boards / fans and wiring. It was so thick that it was impairing the quality of my cuts and engravings. After a full clean and refit I was amazed at the increase in power I had achieved. Although it was not like a brand new 4W there was a marked improvement.
Thinking of adding a separate fan to increase cooling to main board and help to keep it dust free
