That’s okay, let’s talk about the smoke issue first - that’s actually a larger problem.
I take it from your later comment that you are using a Compact Filter, correct? As soon as you start to see ANY smoke come out of the machine, (or puddling inside the Glowforge), when you are using the Compact Filter, it’s a sign that the cartridge is starting to fill up. Once that happens, it can go very quickly from full suction to zero suction and you are going to have a room full of smoke. (Which isn’t healthy for you or the house.)
It’s an indication that you need to replace the filter cartridge promptly. So if you start to smell anything while using the filter, dial up the suction power on the front of the filter box and order a replacement cartridge. (They sell them in the Glowforge shop under the Spare Parts section.)
And sorry to have to tell you this, but depending on what you are cutting and how frequently, you can fill one of those things up in a couple of weeks. They generally run from 20-30 hours of actual cutting time on the machine, for non-Draftboard materials. Draftboard throws a lot of particles and glue and can clog one up to ten times faster. So try to avoid heavy cutting on draftboard if you can.
It’s also been suggested that continuing to run the fan on the filter for an equal amount of time to the cut will keep it from clogging as quickly. You can open the lid and remove your print after the cut, just leave the filter running for a while.
Okay, having said all of that…if the machine is filling up with smoke, the laser beam could be being deflected, resulting in wavy cuts. Also things are going to get terribly dirty in there, requiring more cleaning after every cut. You need to get the smoke back under control in there.
