Flame

[evan]

For about a month we were having issues with our glowforge and realized it was mostly the fans weren’t sucking out the exhaust. So we got a new exhaust fan and cleaned out the internal fans and it started working a lot better on all of our normal materials. Plywood Acrylic etc

But I have someone who comes in and uses it that uses a nicer draftboard and different types of wood and it is flaming a lot more than usual. She even says it never used to flame before we started having exhaust problems. Is there something I might have messed up while trying to fix the other problem? Is there just something I am missing about using nicer wood?

In general, excess flame is an indication that the air assist fan is either fully or partly malfunctioning. It may need to be cleaned. You can find information on cleaning your air assist fan linked in #17 here:
