My Glowforge Pro is still producing a lot of smoke outside of the unit, even though the exhaust line is clear and the fan is running. Any suggestions beyond the default F.A.Q. page? Here are the support threads where I have described this problem:
A video of the problem is available at:
I have gone through all of the recommended self-checks for excessive smoke.
Is that smoke coming from under the glowforge, or is it just a trick of the camera? When I had smoke come out of my machine (forgot to open the blast gate. Turns out thats important), the smoke came from the sides. Well, the sides of the front.
Same if you have much in the way of curves or corners. My vent system, for instance, has 6 () 90-degree corners before it leaves the house, so I have two booster fans, a 600 cfm and a 400 cfm, plus some extra boost from the range hood whose chimney it shares. That reduces my smoke to almost nothing, though I still put blue painter’s tape over the gaps when I cut acrylic.
Okay, it’s hard to tell what’s going on outside of the screen shot, so it helps to ask.
Did you remove the hose from the back of the machine and check the grill over the fan to see if it is clogged? That has to be cleaned periodically or smoke can start pouring out of the front of your machine if it gets clogged.
That is, indeed, a ton of smoke. Might be a trick of the video view but it looks like the Forge is really close to the wall, forcing a tight turn on the vent. Can you slide it way from the wall a little more and “soften” that turn in the hose? Might help with the flow.
Also, no idea if it will help your actual situation, but a booster fan certainly couldn’t hurt. The definite advantage is leaving it running well after the cut and after the internal fan auto shuts-down.
I’ll take some more detailed pictures of the rear of the forge in a few days when I return. I should note that this was working fine for a month and a half and that I still feel significant flow at the exhaust pipe’s exit when the forge is operating.
