Yeah, I think it was this right?

A lot of industry does use grey water or untreated water for cooling as it's substantially cheaper to filter it and add chemicals to it yourself. What's even cheaper is to have a cooling tower and reuse your water, in the volumes it's used at industrial scales it's really expensive to just dump down the drain (which you also get charged for), when I worked as a maintenance engineer I recall saving something like 1m cad minimum a year by changing the fill level in our cooling tower as it would drop to a level where it'd trigger city water backups to top up the levels to avoid running dry, and that was a single processing line.

I can't find much literature about it, did find this safe handling procedures from UNSW Sydney if interested. I'd say if you're concerned, don't use it. The fibres themselves to me are a concern when out of the polymer, so take precautions when sanding or cutting, glove up and wear a mask + eye protection, probably should consider wet sanding too to reduce airborn dust. Print in an enclosure with ventilation, same precautions you'd take for abs and nylon, you don't want to be around that when it's printing. As I said though, if you do have any concerns, don't use it, there are matte finished filaments if thats the look you're going for.

What was CNC kitchen's concerns? As above, personally I'd be concerned while disturbing the plastic through printing, cutting, sanding etc, just handling it wouldn't be on the top of my list unless the plastic has degraded or been damaged in some way, pretty much how I'd treat anything with fine fibres or particles in it.

At the end of it, I'm just some guy on the internet, if you have concerns, don't risk it. If you do decide to use it, treat it with respect like you would anything with fine particles or fibres.

Will echo the recommendations of debian or mint. I have mint on my 13 year old rog laptop, it's my lab computer and runs klipper for one of my printers, pretty much always up, very rarely reboots. Debian is what I run on my 4 year old zenbook s, pretty much perfect for my uses, it's what I cart around for light/mobile work and I swear it actually has better battery life than it did running windows.

A good chunk of it is relating to the elastic search stack, yeah it's a thing people do.

Apparently goo gone has limonene in it, I'd be wary of putting it anywhere near filament depending on the plastic used. I'm personally on the side of clip it and be done, I try to use as much as possible as well, have had the tail out on some spools get caught in the reverse bowden I use depending on the way its been wound, so I do tend to be on the cautious side and why I have smart filament sensors. Would rather lose 5g of filament over failing a print and wasting even more.

KeepassXC seems to register as DRM protected content (I think...) for me, kills moonlight streams while it's up so at the very least using a password manager (which you already should be using) would be protected?

I already daily drive debian on my lab computer and laptop, guest I'll be swapping my desktop over in the not to distant future...

Windows on arm was a thing, I had a surface 2 rt about a decade ago, too bad it never felt like microsoft ever really fully committed to the idea imo, and yeah x86 apps wouldn't run on it (though there was an emulation tool apparently, was community developed). Market was definitely there (though I'm not sure how big it was, probably a cross over with netbook users), they just fumbled it like they did windows phone in my view.

I'll look at it for sure thanks! I think I was going to try it a while back but never got around to it as I figured the tap probe would handle it, found it most important to keep the nozzle clean (shocking I know considering it's my z probe!), I had a cleaning macro before I installed the kinematic bed, might set that up again when I get around to it, need to make some height adjustments to the models as the bed itself sits higher than stock.

I have 2 doors with the 270 deg hinges with latches, but I'm honestly super interested in something like the clicky-clack for sealing, theres a slight gap between mine and I've not got around to making something to fill it without getting in the way. I have little tiny windows on mine (excuse the loose cable, hadn't printed slot covers for the lights yet, just put the covers on today) you can kinda sorta see what's going on but Yeah, definitely relying on known good profiles and stores offsets for each of my surfaces. Tap kinda sorta makes swapping nozzles less of an issue but I still like having different offsets, textured is a bit closer and nylon is just a bit further away.

Super impressive it stayed adhered honestly, I had that happen with buildtak but not with a standard pei surface.

I have ACM on mine, definitely recommend, did need to print thicker panel mounts for them though. Those definitely sound like some decent chamber temps, I've had decent enough results in the 40s, I'd be interested to see where ACM + bubble insulation goes.

What's your chamber temp with bed fans like? I just mounted a chamber thermistor (on the floor, I don't feel like running cables through the drag chain right now) that I need to connect but the little thermometer module on my gantry was reading like 58 ish at 100 c bed temp, dropped to 56 ish overnight, was getting 40s before moving them to the front and actually setting up the automation macro for them.

For impromptu insulation, Cardboard works well too, I stick my filament dryer in a box during the winter so it can actually hit the target temps, otherwise it runs forever.
