Perhaps, but have you actually tested this for yourself?
PLA is extruded at 220C in my Prusa beastie. Once the filament is slapped on the model, I probably want it to to fuse to the previous layer really well and then cool really fast and become stable.
We need to provide working and results rather than “I think that”. My printer is quite close to a very large double doors to outside, which open and shut as required.
It’s complicated but PLA is bio-degradable … eventually. Not months but years. That’s much better than the horrors you see on Blue Planet II.
Plus humidity is bad for your filament.
I keep on hearing this but it does not check out for me.
I have a Prusa 3S+, self assembled. I do not do a great deal of printing and go through phases. I did a flurry of prints during the pandemic and then it rested idle in our rather cold and slightly damp study for a couple of years. When I bought it, it came with a spool of silver Prusament which worked nicely. I then bought a spool of “Sunlu” filament (Chinese firm off of Amazon) and then a box of 10 colours of the stuff.
I recently got the printer out and updated the firmware, re-calibrated it and so on. I’ve done several prints with filament that has been open to the environment for at least two or three years and its fine. I have done a print using some transparent filament which was unopened and that was fine too. The unopened stuff was vacuum shrunk wrapped so could not possibly be damp. The opened filament was stored in the original cardboard box in a slightly damp and unheated room.
For me the main issues for a decent print are:
I will try repeating a challenging print with filament that is way older now and see what happens. I printed a couple of tank models in red around four years ago. Both involved their turrets with the barrel facing upwards - that’s a lumpy cylinder about 4cm long and 2mm wide.
I have seen some notes about PLA being hydrophylic (absorbs water) on the Prusa website’s official advice but I don’t personally think it is an issue and people are probably missing another factor or factors that is fucking up their prints. I think the filament dampness meme is “cargo culting”.
PLA is heated to around 220C whilst being extruded so any water will steam off very quickly as water vapour - which is not even “wet”, well before worrying a print job.
PLA is touted as bio-degradable and it is … eventually. It is extremely stable, despite being derived from corn starch. It really doesn’t seem to care about a bit of water hanging around. That’s why I can print new hinges for a plastic garden storage thing to replace the original ones and they last through winters and summers in the UK.
So, if you think moisture is an issue for PLA filament used for 3D printing, why not do some experiments and then decide for yourself.
I’m happy to be proved wrong.
That is superb. Sadly my eyes degrade faster than the frames wear out!
I see you are on the John Lennon specials which makes it a bit easier to model. I haven’t worn circular specs since college (~1990) My current Tesco specials only have lens frame from the nasal bridge clips, over the top to about 5mm below the temple joints.
Just a thought but you might like to investigate using spring steel for the arms and PLA just for the frames. You could create a jig for joining and heat the ends of the arms up with a brazing torch (kitchen supplies) and sink them into a suitable cylinder close to the temple joint. If you go all in you can make the straight part of the arm rigid and the over ear part flexible with careful heating and cooling and whacking with a hammer!
Now, that metal work will be comfortable but might be a bit chilly. What about PLA tips over ear instead of steel?
Anyway, great job. I’m very impressed.
Lemmy is quite good at not being too “tribal”. Why not embrace a message as expressed, instead of worrying about where it is … posted?
For me, one of the worst issues affecting t’internets is tribalism. Us humans are hardwired to go all in on tribal affiliation. It is generally harder to find inclusive measures than it is to find exclusive measures.
If you are here then you may not be exclusively: Firefox user ⊆browser user ⊆human. Note that browser user can have multiple browsers.
That looks like a cherry picked starting point. Read the whole thread for the full context.
fwiw, I don’t think anyone comes out looking particularly good. However, attempting to describe Frenck as infamous here and now is a bit rich. That minor disagreement all happened during the pandemic and I’m sure we have all passed a lot of water since then.
“Gilfoyle” is an anagram of Cthulu.
Use what works for you.
If the boy has a gaming rig, then he also has a CAD workstation.
I managed to get a dodgy copy of AutoCAD 2 running on my 80286 with an 80287 maths co pro that I persuaded my parents to buy me for Chrimbo. Sadly, it was a bit shite. The next version of AutoCAD needed a 32 bit machine with 32 MB (yes MB) of RAM. That was way out of my league.
Depending on the age of the boy and given how long the little darlings are tending to hang around these days, a constructive bribery system in lieu of rent or pocket money enhancement might be in order 8)
My home and work ones both have Zigbee and Zwave. The modern ZwaveJS integration is amazing compared the old effort. Also: ESPHome, NUT, Mossie (MQTT), nginx proxy manager, MariaDB, nodered, Piper and that, Remote Backup, Terminal and SSH, DSS VoIP Notifier, VLC.
HACS with a fair few custom cards etc.
Chill mate. This is the fedi - you get to actively allow or deny what you see.
No-one can take that away from you.
Blimey there’s a name from the past. I remember painting a Citadel Miniature (white metal job) of a demon of Slaanesh. That would have been around 1986-7ish. Four armed thing and looked bloody nasty! That was before Warty-Forty really took off.
I moulded a little skull out of Milliput, with a tiny snake running in through the base and out of an eye socket. I separated a foot from the base and lifted it up a bit and stuck the skull under it. White metal is quite soft but you have to be careful. I spent quite a while modelling “grass” and such. The grass went from a dead looking green/brown around the demon to normal in a sort of circle of ruin.
Nowadays my eyesight can barely see a 00 brushes’ bristles, let alone let me use one.
SO: Next door have got their lights up, why haven’t we? Me: (Enable NodeRed flows for gutter and pergola light strings that switches them on at dusk and off late evening) Right, that’s the missus pacified for a week or so. I should probably get BigTimer to sort that out itself.
Employee: I’ve got all the printers for <customer> monitored using an auto entries card. (Good skills) Me: (Installs an addon that can use VoIP to do text to speech to a phone) We warn off the customer and now they get a phone call from “things” that tells them what consumables to buy and also sends an email.
When I finally get around to sorting out my glasses so I can see what my soldering iron is up to, I’ll get many more gadgets installed. My computer room at work needs a tiny ESP8266 and four 1 wire Dallas SC temperature sensors, a bit of vero board, a resistor, power and probably a buck convertor and a case, which I’ll print.
I adore HA.
I once named a load of servers for a helicopter company in the UK with elements. The cluster nodes were copper, silicon, etc. The cluster itself was called iron. The volumes were labelled fe_function.
It worked - it was easy to read and the bits that implied “cluster” were grouped appropriately. All the other servers had random elemental names unless they were associated in some way, in which case the group would be used. The engineers (real engineers with oil or distressingly nasty lubricants in their veins) loved it - it made sense, without being too quirky. It was very legible.
When those systems were hoicked out and replaced, the usual nonsense was applied: 2 char country code + 2 char site code etc etc ad nauseam. Followed by my absolute pet hate: 01. Oh so you might need 99 domain controllers? Yes you might, but not on one site.
Let’s face it, it is mostly AD admins who don’t get hostnames. I blame MS - their docs and blogs strive to be … authoritative or at least look so. An entire generation (possibly two) of sysadmins have been sold up the river by MS and their wankery.
That IPv6 forwarding page is strange. IPv6 does not need forwarding.
Anyway, I am trying to find a manual for your router. A Google search shows that it is probably NL localized and probably Asian manufactured for NL ISPs. Are you able to get a manual from your ISP? Their website looks just like one of ours - no help at all. I have also tried searching on the model and not much comes back.
I’m off on holidays for a few days. I’ll be back on dinsdag/tuesday (08/08/2023).
That is for ping. ICMP v6 REQ: REQ means request and is a NAT type of terminology. A firewall rule allows some form of inbound traffic - here ICMP ping inbound (REQ), and then creates a state entry which allows the corresponding return traffic (RESP or response) - pong!
ping can be useful to determine connectivity and that rule will not open you up to anything nasty.
Your router seems to have been designed by someone who gives a shit about security, which is a good sign.
You don’t need to put the IPv6 address into your browser. The host command shows that you have got DNS sorted - try:
$ dig @9.9.9.9 myserver.now-dns.net AAAA
That should return an IPv6 address and the @9.9.9.9 means: use the Quad9 DNS server - 1.1.1.1 or 8.8.8.8 will also try external DNS servers - CloudFlare and Google. Hopefully that’s naming sorted out.
Now to actual access. Your router will (probably), by default, block all inbound connections. I’ve just had a look at your screenshot and it has a menu entry: “Port forwarding IPv6”. IPv6 doesn’t need port forwarding really but I suspect that is how you allow access. I am now guessing. There is such a thing as IPv6 NAT and something called NPT (Network Prefix Translation) which is not for the faint of heart!
Have a look around in that menu a screen shot might help.
It might help if you tell us where you are (very roughly - country and perhaps city), your ISP and router model. I can get you to the point of all of this working but there are rather a lot of unknowns. I can see that your router offers Dutch or English so I will guess you are from the Netherlands.
As well as a link local address you should also have one or more globally routeable ones too. Hopefully you have at least one of those set up in DNS with a AAAA address. Therefore you should be able to put the address of your web server into your browser and off it goes. In theory IPv6 should be preferred by your browser, so even if both an A record and a AAAA record resolve for the name, IPv6 should kick in.
A quick check would be:
$ host mywebserver.example.co.uk
That should return an IPv4 and an IPv6 address. The IPv6 address is the same for internal and external - there is no distinction, which can be surprising if you are used to IPv4 and NAT. The final bit of the equation is that your internet router needs to allow access “from all to globally routeable ipv6 address of the web server”.
I can see that you have bound nginx to port 80 on both IPv4 and 6 - the two Listen directives.
Let’s get right down to basics:
I’m on GMT+1/BST/UTC+1 so its a bit late now. I’ll pick up tomorrow pm
Good skills Sir! Advice noted and I will re-evaluate how I do specs.
Thank you.
