Lasering Sand?

Well as the filter is mentioned in item 7, i.e. under the heading “Just one plug” I think it is not unreasonable to think only one plug was required. But not a big issue as it can be fixed with an adapter. The desk I intend putting it on has six switched outlets and is only just big enough to have the GF standing on it and nothing else. So I will have four sockets spare.

What I was asking @dan was can we switch from filter to outside hose mode by just switching off the filter and removing the U bend and connecting the hose? I.e. is the GF happy to have the filter electrically connected but not active?

It is somewhat strange that it uses a separate cord. I mean why not just have a single power cord with either a double head or a jumper cord (my mac SE way back in the day had a jumper cord to power it’s external rodime HD (that monster 30mb drive!). One end of the jumper was the regular IEC cord and the other was a strange double ended IEC connector male-female so you plugged it onto the end of the cord. A splitter connecter cable is a standard thing in data centers (I bet GF’s cloud uses a whole slew of them in fact)

Here is one rated for 15A

Yes especially as they boast “Just one plug” as a super power. If they hadn’t I don’t think I would have found it strange.

The good news is we can solve it for $10 at amazon…

Thanks for the correction.

The Glowforge does communicate directly with the filter.

Unfortunately we can’t support non-Proofgrade materials, so I can’t say.

Yes.

It’s not uncommon in our experience for people to want to plug the Glowforge and the air filter into separate circuits. They can both be on the same circuit, but there shouldn’t be much else on that circuit.

Wondering aloud whether this is in-house testing or the super secret beta-filter testers. Given the size of the Purex filter at BAMF, when the Glowforge filter debuts and works perfectly, this is going to be a game changer. Hope it all works out as planned!

Ya know, with all the discussion today about the one connection Glowforge verbage I’m really happy to see a little engineering common sense.

One of the big positives of having separate power cords for the Forge and the filter is that it will be easier to use a battery backup, if desired. It would take an enormous and expensive UPS to protect both through one power cord.

I expect the forge would error if you switched off the filer while it was running.

Perhaps, but it will be less expensive to use two UPSes with two power cords than one with a combined cord.

OK, but they could ship a splitter cord (like I showed above) and you could always switch. Of course we can do the reverse (which I will - since my use case for the filter is makerfaires and class room, rather than at home, where I don’t care)

I was talking about if they had powered the filter through the Forge using only one power cable, you would need a large, expensive UPS. It was a reflection on the positive side of having two cords.

All of this together might end up giving me 3-4 UPS…:glowforge:, filter, and at least 1 PC/Cable Modem.

Did you ever get a response on this? I can’t decided if they should be listing these materials on their site if they aren’t going to give support for processing them. I love the proof grade, it makes life easy, but it’s frustrating that seem to want us to use only proof grade.

Stone and glass do not burn. No need to vent them. No smell. No smoke. (Does throw a light that’s too bright to look at…be careful.)

The glare is quite amazing…
