It does sound like your filter is full.
After 2 weeks of use?
It depends on the materials you’re using, but yeah, they can easily fill up that fast with frequent use, especially with things like draftboard. People have had some success using inexpensive prefilters to lengthen the lifespan – a forum search should bring up some ideas.
Mostly basswood plywood and draft board and one acrylic burn. I only have about 6 hours of use.
Draftboard is the worst offender, and some of the plywoods have it in the center. I’m betting that’s your culprit.
Do you work for Glowforge? Come on, six hours of usage burns up a $250.00 filter. No way.
Draftboard/MDF fills it up extremely fast - which will also cause your overheating issue.
If you want to test this out, run the vent hose outside -
Or, just disconnect the hose, open the gift of good measure, select thin leather, and run the job on an empty bed.
I’m just another user. Check the forum. There’s been a lot of discussion of this issue.
Unfortunate awakening, but yes - the filter is a consumable. Here is a thread from another customer in disbelief.
I totally clogged a filter in just over an hour. One single engrave job on a material that threw off much finer dust than I expected. The filter worked great until it didn’t. I was using a non-proofgrade material that I think was mis-identified.
That was an expensive evening.
The most use I’ve got so far is about a month with moderate use and carefully selected materials (no draftboard, no baltic birch or fiber board). I haven’t come up with a way to extend filter life that I’m happy with yet so I still do a lot of “hose out the window” cutting.
Glowforge estimates the lifespan of the filter cartridge when cutting plywood at just 32 hours, and fails to provide an estimate for Draftboard except “dramatically lower”.
Going back and reading through that post, I think they should display that cost in $$$ / month. Most users won’t think twice about the realized cost until the one Saturday they burn out their entire filter after a full days use, and subsequently get angry at Glowforge for not being “upfront” about it.
If the filter read something like on average $50/month for ~7 hours use. People may think twice about buying one. Most people pay less than that for their internet.
Thank you so much for sending over these images, and supplying such great information. I’m so sorry to hear that you ran into trouble 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.
