I know this is all covered on Glowforge’s manuals but I made a quick video showing all of the most important areas to clean most often on the Glowforge since it gets asked often and it seemed to help a people out in the Facebook groups too:
Hopefully it helps some people out. I explained how the machine and these parts work towards the end of the video too. I still recommend using the official cleaning guide too that you can find under the support tab, I just know sometimes visuals and explanations helps by video.
