While I'm at work, I'm going to get this guy printing the B-2 Spirit model someone mentioned up-thread. Replaced the filament with black, and it should be done-ish by the time I get home.
Is that safe to do?
So long as you trust your printer.
For mine, if the filament gets stuck, it's stuck for good, so the printing effectively stops. In others, it may be stuck only for a while, and then get un-stuck, and then you're usually extruding into open air, which results in a bunch of plastic hair (effectively, wasted).
Meh, that part I don't care about. I was thinking more along the line of "Can you trust an automated machine with parts that are several hundred degrees that melt flammable material to run while you are gone for several hours unsupervised?".

Meh, seems the news talks about it once a year or so. Not very prevalent unless you take poor care of the device, which could apply to many things that plug into the wall (though, admittedly, not many that run unattended).
-
@polygeekery That pretty well demonstrates the need for the MOSFET power board upgrade on my printer.
-
@mott555 I believe you have done that? Do you ever worry when you are away from home and it is printing that it could catch fire and you would not be there to put it out?
-
@polygeekery It was one of the first upgrades I did, so I don't worry about it catching fire anymore. The print bed had an undersized power delivery circuit which supposedly didn't matter unless you print things that aren't PLA.
I'm more worried about that self-igniting furnace I have which has no pilot light. That thing is scary.

Not to go off on a tangent, but why? Your furnace likely went through vast amounts of testing and follows industry standard protocols for how to do what it does.
Your 3D printer was probably designed by some college kids who may not have even completed their engineering degrees and then poorly copied by some Chinese guys who were only worried about cost and select components based on what is cheapest at the Shenzen market this week.

Yeah I understand that intellectually, but there's still something unsettling about it. Especially since I work in an engineering field and see plenty of incompetence in an industry where even a slight lapse in safety would have huge implications.

It's pretty self-contained though. There's no way the nozzle could come into contact with anything flammable, and if something went into thermal runaway I'd expect a circuit breaker to pop pretty quickly.

In actual reality, I expect that most (all?) fires start because basic safety measures were not taken, i.e. the printer would be too near from a curtain or other flammable material. The same probably applies to most house fires. The key reason your furnace is unlikely to do this is that there are strict installation requirements, so it should not be too near from highly flammable stuff, might require (or include) some additional wall insulation etc. (all installation manuals I've seen take great pain to lay out safety distances, and I would be surprised if some of those weren't actually officials regs/laws). 3D printers might have this kind of warnings in the manual, but let's be honest, how many people will have even simply read those, let alone followed them?
So IMO, not only is your furnace by itself less likely to catch fire, it is also much less likely to be in a place such that a small fire would turn into a huge one.

@remi said in Today in Blakeyrat is always several years behind in every tech trend news...:

The furnace ignites itself by blowing propane over some kind of glow plug. My hypothetical concern is that the glowplug could fail, allowing the furnace to fill my apartment up with propane gas. At that point any source of ignition would result in a nice little mushroom cloud over my neighborhood.
I would assume it has a temp sensor and some kind of ignition timeout. But I'm not a furnace engineer, nor did I sleep in a Holiday Inn Express last night.
-
I'm really enjoying this printer.
I came home yesterday and found that the filament to my secondary extruder had broken at some point. Luckily that's only used for building support, and I'm at a point where no support is needed for the moment. So I paused the print, fed some more filament into the extruder, and resumed the print job, and it started right back where it had left off without a hitch. :D

You'll notice that requirements for furnaces also mentions ventilation around it, with AFAIK direct venting to the exterior of the building. Probably not enough ventilation to make ignition of free flowing gas impossible (although I'm no specialist, maybe it is?) but that would certainly mitigate the impact (which concentration of gas is actually needed to have it blow up when ignited by a spark, and the resulting explosion to actually ignite other stuff? I've played a bit with gas canisters in camping and it's far from being as dangerous as in movies...). Again, 3D printers probably haven't got these safety measures, or at least people probably don't care about those.
I would assume it has a temp sensor and some kind of ignition timeout.
I guess, yes. It might even also have some kind of oxygen probe (which might also help in case the CO2 -- or worse, CO -- concentration got too high), although that probably requires some more fanciful electronics. In any case, there are literally millions of furnaces installed, and the technology has been used for a century or so, so it's likely it has been thoroughly tested and failure points identified!
-

If my recent experiences with technology are any indication, then that's probably not the case. Or, it does have a timeout that's way too long (i.e., still filling your apartment with propane gas), and it simply retries engaging the glowplug when detecting the failure (producing said mushroom cloud autonomously)..

@cvi Please stop talking about furnaces.
I don't mind topic drift, but why the fuck do you guys always have to drift it into the MOST BORING TOPIC POSSIBLE? Nobody gives a shit about furnaces. Nobody (sane) gives a shit about the tiny details of the C++ specification. Talk about something interesting for once.

@blakeyrat I think not, tariffs in shitholistan are sky high, no matter where the stuff is coming from. We gotta protect our non-existent industry.

@sockpuppet7 When I visited New Zealand they had like a 20% tariff on all computer equipment and had for several years. I remember a conversation like this:
"What's the point of the tariff?"
"Well the idea is if you make foreign computer equipment more expensive to import, it'll encourage companies to move manufacturing to New Zealand."
"Ah. How much computer manufacturing is in New Zealand?"
"None. People can't live without computers, so the customer just pays the cost and everybody loses."I think at minimum the New Zealand government vastly underestimated how expensive a chip fab is to construct and operate. Way more expensive than the tiny amount gained by out-competing some other company by lowering your prices 20% in a tiny country.
-
@blakeyrat Our import tax is 60%. Then there is a vat-like tax over that. In the end, its 90%.

Somewhere between $1E9 and $20E9, or roughly $200 – $4000 for every man, woman, and child in NZ. Or 0.5% – 10% of the entire country's GDP. </>

Trying to figure out how to extract models from ESO to make my own action figures... holy shit I successed:
-
@blakeyrat It looks like some of the normals are facing the wrong way. I don't know whether that would confuse slicing software for printing, but it's easy to fix. Other than that, looks good. Why am I not surprised you'd pick a khajiit for your first figure?
-
@hardwaregeek The guide I'm following mentions a lot of the ESO models are that way for whatever reason. There's a command in Blender to fix the normals automatically so it's no biggie.
And that model's in the app because it's literally the first 3D character model that loads on my ESO connection screen. I'll probably print a Khajiit, but if/when I do it'll be Drozahn first.

The printing itself, not so much. Attempting to set up support, (which that model will definitely need,) on the other hand, does require your normals to be facing outwards rather than inwards.

My goal is to do enough rigging that I can pose the character to avoid supports. Which I'm a long way from, because that also involves learning enough Blender to do move bones around...

So we've all see the old sitcom cliché where the clueless husband buys his wife, for her birthday/anniversary/etc, some completely inappropriate, highly "masculine" gift such as power tools, and hilarity ensues.
Well, my wife is awesome! The helmet I've been trying to print finally finished last night sometime after bedtime. She saw it this morning as I was finishing cutting the support material free, and saw it had left behind a bunch of little residues at various points. (Dual extruders are awesome, but they can also be a bit messy.) She took one look at it and was like, "you know what would be great for cleaning that up? A power drill with a sander attachment. Want me to pick one up while you're at work?"
-
@masonwheeler Might be an ESL thing, but 'power drill' screams 'big' to me. Wouldn't something small like a dremel be more practical?
-
@blakeyrat They seem to have that on TOP of the 15% sales tax on all goods - which is why a $30 game in the US is 100NZD. Anything tech related is awful there. I still occasionally have the urge to move back there, though.

This is a hand drill, shaped more or less like a large handgun with a battery pack attached to the butt.

@masonwheeler I'd think you'd be better off with a power sander, since you're sanding, and also they're cheaper.
Or the Dremel idea with a sanding disk is good too.

And less versatile. A drill can also hold drill bits and screwdriver bits. The latter is generally useful, and the former is something I'll specifically need for this project.
-
@masonwheeler How have you gone this long without a drill anyway? It's a pretty necessary piece of equipment. I figured you had one but it was just too shitty to take a sanding disk.
Also if you want a power screwdriver, get a power screwdriver. The amount of torque and speed required is ENTIRELY different for a screwdriver than a drill. Despite looking similar, they are really completely different tools.

For what? It's not like I do much woodworking or home remodeling work, and the 3D printer is new.
One other cool thing a hand drill can do: you can attach a scrub brush to it for high-powered tub/tile cleaning. We actually did this when changing apartments, and it was way better than any other method I've seen. (She borrowed her brother's drill for that.)

I've used hand drills several times as power screwdrivers in the past, back when I was living at home and the folks had one. Since then I've managed to get by just fine with hand screwdrivers. Actually drilling holes, I haven't really had much need for. Last time I can remember doing that involved making a small hole in the bottom of a large plastic piece of outdoor play equipment for children, so that water that had gotten inside somehow could drain out so that it could be moved more easily. And that was close to 10 years ago.
For this particular project, I can definitely foresee the need to drill a few holes, though, so it's a good time to pick one up.

I got a power screwdriver recently, and only perceived after openin the box at home it's also a drill. It worked fine for screwing stuff, I have yet to test how it drills. I already had a drill, so I guess I chose poorly. Or maybe not, this one has a battery, and the drill needs to be on the outlet.
It has a setting for the torque

@sockpuppet7 I'd worry the gearbox is too delicate to do both tasks, especially if it's switchable. It's not like a car transmission where everything's steel and bathed in oil.
But hey if it works, it works.

Yeah, rigging could be considered an advanced topic. Posing a rigged figure is easy enough, if the rig is good and you're not trying to do extreme poses (e.g., yoga or martial arts). Creating a rig is a different skill level. There are some pretty good tutorials out there. I've only really tried one from scratch, for a quadruped (horse), and I've never gotten around to animating it, so I don't really know how good a job I did. It's a little easier if you're only interested in static poses, like for printing, rather than animation, since if joints look a little off, you can just fix them without having to worry what they'll look like in a different position.

All the cordless drills I've ever owned have had a gearbox that can be changed between high-speed, low-torque (drilling) and low-speed, high-torque (screwing ) with an adjustable clutch to avoid stripping the screws. One of them also had an impact setting, but I don't think I ever used that.

When I export a model that looks fine in Blender (including the normals) to STL, my slicer app shows a big like empty spot in it for some reason, which breaks the print.
Actually even worse, the slicer PREVIEWS the file correctly, but when I hit "Slice" and do preview there's cut-out places.
Any ideas?
