I’m surprised I can’t find a video on the Glowforge site for the Air Assist cleaning. There is a lot on You Tube … Who is your YouTube Channel Go-To for Glowforge help? Specificially the Air Assist Fan cleaning?
Not a video, but pretty clear instructions, in my opinion. https://support.glowforge.com/hc/en-us/articles/360034142513-Cleaning-Your-Air-Assist-Fan
And when you’re cleaning the fan, take a look at the air channel - I’ve had some clogging more than once.
Thank you … I’m feeling brave enough to tackle this now.
