Flames when cutting

So my glowforge is now cutting with flames. I don’t know what to do.

If anyone has had this problem or can give me any tips. Please & thank you

Check your air assist fan on the back of the printer head,

As mentioned. Assist fan.
It gets missed during cleaning sessions by people, until everything they laser is on fire.

thank you.

That burn looks awful wide. Are you sure the lens is in correctly?

Always worth checking, but it appears to start normal, then the heat char started crisping everything.
Been there. Done that. Got the banner.
Do not skip the assist fan when cleaning.

I’m sorry that you’ve hit a snag with your Glowforge. I see you already emailed us about this and we’re working on it there, so I’m going to close this topic.
