Replacing Filters


#10

It’s difficult to estimate how often the filter cartridge needs to be replaced because it depends not just on how much you use it but on the material you use. Hardwoods aren’t very taxing but plywood might be, depending entirely on the glue (which is usually hard to figure out). It’s just going to vary a great deal, with light users pushing past a year between changes, and heavy users who are cutting nonstop turning them over as often as every month or so. We’re working on filter pricing, but we expect it’s going to come in under $250.

I hate to point fingers elsewhere, but we looked for other laser filter manufacturers’ filter life estimates, and can’t find them either, so apparently we’re not alone in finding it difficult to put numbers to it.


Replacement Filters for Air-filter
#11

Hey Dan & team
Will there be some sort of indicator to notify us when the filter needs to be changed? Either locally with an LED or in the cloud/app? Or would we just need to “eyeball it”?

Thanks!
Adrian

No eyeballs. : ) We’ll be able to notify you when the filter’s in need of replacing via the cloud service. We’ll also look at using the local LED for that, too.


#13

This is exactly what I was hoping to hear.

Thank you!

Hrmm is that the duct size for the units with the filters? or for all glowforge units (basic, basic with filter & pro)?

On the tested video I thought you said that the duct size outlet was about the size of a vacuum hose? Is that the case? Or has that changed?


#15

From what I’ve seen here on the forum @karaelena it seems it is 4" in diameter or similar to a dryer hose. @dan mentioned in one of the threads that you could purchase it at Home Depot for $10


#16

Yeah I saw the link for the Home depot hose… But I am just confirming from what I saw in that video.

But from the forums (not from the tech specs page) its a 4" dryer hose. Just trying to get the fact right.


#17

“Our standard model needs ventilation via the provided 4″ (10.2cm) hose. We recommend putting the hose out a window.”

I thought I read thru the page. But I missed that some how.


#18

So the Glowforge will have to be removed from the filter in order to replace it? Too bad it’s not some sort of a slide-out mechanism…


#19

Yes, you have to lift it to get to the filter.

All this talk about the air going out of the GF, but where does it go in - is there a port for the air going into the GF? It’s occurred to me that the GF is essentially a $2,000 vacuum hose attachment - with an ignition source inside - woo-hoo!


#21

I think the answer to your questions is in these two replies from dan.


#22

Thanks @rpegg. From what I saw at CES, the water cooling system is entirely on the left side of the GF, so the air inlets should then be on the right side. I saw no inlet vents as it sat on the table, so are they underneath? - are there any pictures of the bottom of a GF?

I’m thinking about constructing a simple filter for the air going into the GF, as I can’t think of any positive outcomes from dust accumulating inside the laser cutter, given the laser beams, burning materials and high voltages. My PC cases get pretty dusty inside, and their fans run considerably lower cfm than I expect the GF does.


#23

Haven’t seen any pictures. If I had to guess the inlet would just be slots vs. an input port. Don’t know where.


#24

The air comes in on the bottom of the Glowforge, on the right hand side.


#25

Thanks @dan. Don’t suppose there’s a photo someone could post of the bottom of a GF?

I’m picturing a simple (laser cut of course) bracket to hold a sheet of reticulated foam over the input slots/holes/whatever.


#26

I think I posted one on the forum a while ago (when Xabbess was asking about the arrangement of the feet on the underside) but I may be misremembering.


#27

I’ve read every post so far on this site, and don’t remember seeing a shot of the bottom. Just searched again, and your response to Xabbess was


#28

Yup, no pics of the underside, sorry about that.
