Oh, I didn’t mean to come off as dissing Prusa in general. I ponied up for an XL and it’s night-and-day better than any previous printer I’ve owned.


If this was during an auto level, it’s my humble opinion that this is a manufacturer’s defect in the machine that caused the damage. There should be proper coding to ensure that any increase in sensor pressure by (delta p) halt that machine and that there should be a pressure offset in the sensor such that a loss of signal or anomalous zero reading or lack of reading is done prior to levelling to ensure that a sensor failure has not occurred. My XL freaks out if a fan isn’t spinning at the right speed, so they clearly know that a nominal operational check before the print starts is proper engineering design.

Of course you won’t get anywhere. Unfortunately, a lot of 3D print failures really are user error so I suspect that’s their default response and it takes them a good deal of proof to push them of that mark.


Not to defend them or minimize the corporate stupidity, but it sounded like there were less than 100k people affected out of tens of millions (100m?) accounts. I get that it was a big deal for those affected, but a 0.1% outage doesn’t seem “major”.


The description of an unexpected/(impossible) orientation for an on road obstacle works as an excuse, right up to the point where you realize that the software should, explicitly, not run into anything at all. That’s got to be, like, the first law of (robotic) vehicle piloting.

It was just lucky that it happened twice as, otherwise, Alphabet likely would have shrugged it off as some unimportant, random event.


Which is great if I were storing it and only opening the box for a new roll. I expect to open the enclosure multiple times a day when I’m working with it and the moisture would quickly require recharging. Also, since the box will be accessible for two printers sharing the volume (I might be able to isolate them, but it makes the working space more difficult) and there will be two doors it will be impossible to create it at the budget level I’m considering. Management of moisture, in this case, is a more achievable engineering solution than perfect moisture isolation.


Is anyone using a peltier dehumidifier in a drybox?
I'm reconfiguring my printing closet (~6'x6') for a new printer and thought about enclosing the printer in a moderate sized cabinet (~2'x3'x6' - one "shelf" of the closet) for thermal control. Since there will be inevitable opening and closing, as well as just normal infiltration of the ambient air (usu ~65F between 40-75% RH) it would seem like a good application for a Peltier dehumidifier to keep the RH in the chamber low and reduce my need to re-dry filament which has been on the machine during (inevitable) multi-day or -week downtime between projects.

<- gallery of parts https://imgur.com/a/dkILl03 I've been wanting to try and make a mount for space gaming to go with my office chair - a Steelcase Leap. The organic-ish arms didn't make an easy way to create a clamp system, but in fooling around with it recently I noticed I could remove the armrest pads and they had a nice 4-bolt pattern. Since this is my office chair I need to be able to swap in or out of gaming setup easily. I added a 30mm tall adapter that lets me slide a 6mm x 30mm (actually, 1/4x1-1/4) bar in and secure at the back, with a plate adapter to mount my old HOTAS4 to the bar, and a pin at at the rear for quick release. The plates and adapters are eSun PLA+ which is fairly stiff but has some durability/ductility to it. The bar was supposed to be 6061-T6 aluminum but I was lazy and didn't feel like making a mess in the shop, ripping down some surplus plate I have, and I was too cheap to go out and buy 1/4x1-1/4 steel bar stock so I decided to print the bars from PAHT-CF (high temp nylon with carbon fiber). The 385mm bars just barely fit diagonally on my CR-10s.

Which is why the Moderna vaccine will be priced at just 95% of the cost of the repeat treatments and hospitalization plus the value of the time saved and pain and suffering avoidance by the patient. Say, an extra half a million. I mean, what price would you put on avoiding seeing your parent or child subjected to round after round of chemotherapy?


I still wish it could render rich text and pdfs/attachments in the composition window, but other than that (and lack of native ocr) it’s been a perfect EN replacement for my uses.


Banana for scale but, also, the desk is 6' long and the *little* monitor is 43" (and will be re-purposed elsewhere).

It appears to be built specifically for designing electronics enclosures with 3D printing in mind. I’m sure it’s a great utility, and I don’t mean to argue to no end, but to me a tool built specifically for 3D printed design would have core functionality which offers layer line alignment and orientation, custom and customizable internal structure (what we call “fill”), and a parametric engine to adjust the design and internal structure based on layer and nozzle thickness. While these are all currently slicer-like functions, slicers are absolute trash at being able to customize a part for strength, stiffness, and failure mode selection. (Yes, I’m a structural engineer - I actually do know about these things and design for them - usually being at odds with the slicer over just such effects)

Anyway - I’m sure Dune3D comes in handy for its designer’s purpose, and I’ll probably file this for the next time I think about fighting a Pi case in CAD.


No, no - they’re not raising the price; they’re rebalancing it to reflect the value it delivers!!1!

And since they’ve reduced the free version functionality significantly, I believe I’m due a substantial rebate.


Oh, AutoDesk...you have such a way with words. Honestly, I would rather learn to design in OpenSCAD than send AutoDesk a single penny.

Anyone gaming/working on a Samsung QLED 8k?
I may have the opportunity to upgrade my home office from dual 42" 4K panels to a single 8K panel. Actually, the two 42" won’t fit as my new space is limited to a 72" maximum total width so it's drop to one monitor or go big. I’ll be moving my gaming rig into the office so gaming performance will matter but probably only a couple hours a week vs 50 hours of CAD and office apps. Although the easy answer is to grab the Samsung QN900C, it’s realistically more than I want to pay. I’m curious if anyone can say that there’s any day-to-day difference between the 900C flagship and either the 800C (or last year’s 800B) while I’m out looking for deals this week. I’m currently disregarding the 57" dual 4k gaming monitor due to the curve (it would obscure half my desk).

I suspect it’s mostly a function of mass availability. Even here in the states ground source heatpumps are rare, even though the systems are more reliable (since there is no equipment exposed to weather) and a shallow borehole isn’t excessively expensive.

I’d forgotten about heat pump clothes dryers. Those are fascinating, and really interesting for older buildings or locations without close access to exterior venting.


Good Lord - $2600 for a whole house system? I think that’s what my local (mid-Atlantic US) HVAC shop is getting for a single-room mini-split.

Wait until people find out about ground-source heat pumps and water heater heat pumps. What you get out of those is more consistent year round, too. It’s almost like leveraging technology has benefits over just burning carbon and hydrogen to make heat.


The thin glass substrates do add some rigidity, but the more rigid a frame the less stress is borne by the glass under impact. I would not be surprised to find the frame is mostly Al. It’s light, and strong - common, properly tempered alloys are as strong (yield, not ult) or stronger than stainless. Of course the 1/3 density comes with just 1/3 stiffness. No free lunches.


Steel ( including stainless) is up to twice as stiff as titanium - meaning it flexes half as much under load for the same thickness/shape. It’s also almost twice as heavy. To get a rigid material that is also lightweight, you need to look at exotic alloys like beryllium-aluminum, but the trade off I’d often poor toughness (fracture resistance) and difficult manufacture.


If I was single and working 4-10s or 3-12s and wanted a way to just crash where I didn’t need a car or commute, and it would let me live the rest of the time out of the city, I’d probably do this. It reminds me a bit of the bunk houses of the early 20th century.

It would be a shitty long term existence for most but I can see its utility. Back when I was in college, a friend shared a 3BR with 5 other guys to make living near Julliard affordable. Note that I’m looking for space for the next generation of students I’m seeing tales of 8 people sharing 4 br flats in Edinburgh.


Emergency? You mean kind of emergency where I have to call my naval architect to lengthen my new summer yacht by another half a football field because I need to spend this profit windfall. -Power Co execs in TX


This is exactly what I do. I had a couple retractable cables let over from my wired-VR days and rigged it up on my CR10s. Works great. Here’s a pic - they tops are just connected to the top rail with a rubber band for easy removal. (this was take through the “window” in my enclosure, so you can’t see the top)


I live in a small town with a large college. The students just came back for fall semester. I believe we have quite a few candidates for your list.



I’ve owned 3 printers, all cheap. For what I spent fixing it upgrading them I could have bought a Prusa. More than saying my next printer will be a Prusa, I can say that I actually have one on preorder.

Also, I will never buy a fdm without a bed leveling function. No, it’s not necessary, but if you want a low frustration printing experience, it is - in my direct experience - essential. Prior to having abl I would keep an eye on every print start. With abl I send a job to the printer and check on it when I get around to it.


Wait, so of the five apps they will “let” you uninstall now, one makes little sense to have in the consumer edition (remote desktop - which is effectively enabled in Pro only) and one is getting deprecated (Cortana - bye bye!).


Lots of them, but normal doesn’t sell advertisements or make headlines. I see by the downvotes (or whatever Lemmy calls them) that you’ve been visited by the Reddit groupthink. It feels weird when it happens. Some of us just want everyone to get along…which feels radical in its own way.


I like my vehicles like I like my software - buy once for the features that exist now; upgrade when there is a compelling reason to do so. This rent-seeking subscription bullshit is crap.



The obvious first step is revocation and personal barring for life every single person who participated in the communication from holding a SEC license. The second is jail time for anyone who did it willfully. The third is revocation of their corporation or, in the interest of stockholders who are about to become personally liable, a 50 year probationary period in which revocation of corporation is automatic should any other infraction come to light.


Revocation of corporate status. A corporation is a status set out in US law. No corporate status, no legal protection for officers or shareholders. All liability falls personally and directly on the owners.


Those are the worst looking d20s I’ve ever seen.

;-)



This may be better explained through the lens of different departments within mega corporations. Alphabet constantly changing their messaging platform is bullshit, but their aggregation and ui for viewing not just the entire world maps but creating timelapse views of the planet is quite innovative and just one of thousands of research projects going on under their umbrella. Meta creating yet-another messaging clone in Threads is bullshit, but the research and development in optics and other fields as part of their VR work is actually quite cutting edge. Outside of tech there are also massive research bodies working behind the scenes. The recent adoption of decades of work in mRNA is a huge leap forward in vaccine work, for example. Many large corporations have these internal groups pushing the bounds of physics, and the scale and specificity of research today is orders of magnitude beyond where we were in the early half of the previous century. As we look back at the turn of the next century, I expect there will be a laundry list of technological turning points which are credited to today’s companies which just aren’t apparent in the din of 24/7 news and information. OTOH, thanks to these mundane communications services, we no longer need just a couple of research centers and, instead, we benefit from a larger network of investigators scattered about the world.


Where is the Bell Labs? The Skunk Works?


a country that is not your own

Well, the already own the US (or at least most of the congress); why not try and expand?


Like most scientific and technical advances, it could be an amazing tool for personal use. It won’t, of course. It will be used to make someone rich even richer, and to control or oppress people. Gotta love humanity.


I’m architecture-adjacent, so I’m working with clients across a bunch of different market sectors, many are business owners, but my avocations are heavily into performing arts so many people I know in that group are a pretty substantial cross section of low to moderate wage, often entry level workers. I also own my business so I’ve been in the hiring and training side of things.


It’s the march of progress, but it’s coming for previously “safe” jobs. I make a good living as a consultant, but about 80-90% of my job could be automated by AI. I just went to a conference in my field and everyone in the room was convinced that they couldn’t be replaced by AI - and they’re dead wrong. By the time my small corner of industry gets fully automated I’ll be retired or, at the least, in a position where I’m the human gathering the field data and backchecking the automated workflows before it goes out the door.

political capital to implement a UBI

I applaud your optimism, and genuinely hope you’re right.


presumably a human who works has some intention … to succeed at work

Which is the one in ten who really love what they do and want to go into management or oversee the process for professional fulfillment. Of the other nine, three are waiting to move to a company that pays better, two will decide they don’t like it and change careers entirely, and four really are terrible at it but HR decided they met the minimum requirements and would work for entry level wages so they’ll be in that job for the foreseeable future with zero upward growth, eventually getting bitter and doing a worse and worse job while complaining about their lack of promotion.


They’re scared shitless of wireless / 5G/LTE providers offering service. I’ve never seen so many scare ads about how three old ladies watching YouTube will yank your home wifi or that you’ll have to cut down every tree so you can see the cell tower to get service.

The only places they were installing faster service is where they have competition from fiber and with viable wireless competitors they’re running scared.


I use a 3M 6200 half mask and 60923 cartridges. They’re good for organic vapor, some acids, and P100 (99.7% particulate blockage including oily particulates )I keep it on a hook near the door and use it for painting and epoxy work in closed areas. Cheap and effective, iirc the cartridges only need changing every 100-200 hours of use.


Reminds me of big corporations, most of the time. My personal identification has been leaked or compromised by dozens of companies - some multiple times.

People also tend to underestimate the scope of something as large as the government. The US government is not just the biggest employer in the US, but is the largest by almost a factor of 2 (2.9M to WalMart’s 1.6M). It’s been around longer than basically any corporation in America, and was often on the cutting edge of IT, which means the number of legacy systems involved in anything is an order of magnitude larger than any private entity. Throw on the pile that many government systems are consider life or safety critical and cannot be taken offline very frequently for maintenance (ATC, military, food and health services, etc) and that they are often delicately intertwined with other systems (gotta make IRS talk to BLM for ranchers, for example) and the “simple” process of upgrading becomes a quagmire very quickly.

Not to mention that the US has a fixed scale of pay, and the IT salaries you see at most large tech firms would not be tenable to the governments bill payers (aka you and me, as represented by 535 men and women who need to be re-elected every 2/6 years).


drifting out of their allocated band

That sounds like a violation of regulatory authorization. Tell his ass to fix it or shut it down. If he can’t, revoke StarLink’s status as a US corporation.
