Lots of good recommendations here, my usual recommendation is that if you want 3d printing for a hobby to get a Bambu or similar because they just function out of the box for basically all materials. If you want 3d printing to be the hobby then a Prusa or Voron as others have said, way more tinkering to be had. Both are lots of fun though!
I just wanted to add this video to your comment because e-ink is so cool and this guy has a bunch of macro shots of the displays that are awesome and you can see the particles in the screen changing colors.
So cool!
I found this diagram on SO at one point but I can’t find the post and it is the best explanation I have found for how all of the files work for bash and zsh, each color is an individual path of execution (eg, follow the red line).
Bottom line though, it only really matters if you are overriding something that is already defined, for example I tell my users to use zshrc and I provide defaults and common things in zprofile because zshrc is executed last when they login.
This guy’s channel is so awesome, glad to see it posted here. He has all kinds of cool tools that he built in his lab like a scanning electron microscope. His videos on atomic force microscopes and laser lithography are really fascinating as well, he is really great at explaining the concepts too, definitely recommend!
+1 for Raindrop, that app is amazing, I keep watching for a self-hosted version/alternative that is as good and they are getting closer. The killer feature for me is being able to highlight stuff and then when you visit the site again you see what you have highlighted (in addition to saving them elsewhere). I also pay for premium because it’s great, I don’t use a ton of the pro features either.
So if I understand this right you will need to change the network on the port attached to the synology in your UniFi configuration or set the vlan tag in the synology OS, I would do the former. It sounds like you just added a second network/vlan to the existing interface which means you actually created a trunk and are getting the old network untagged and the new network with vlan tags which the synology is dropping. Synology OS also doesn’t really support trunked ports through the UI (even though it does support a port that only uses a vlan tag) so it’s much easier to just leave them untagged.
This is awesome, I look forward to the weekly updates and have found lots of great tools from that. Keep up the awesome work, it is very much appreciated!
Hah now this is a great shower thought, if you want some existential dread you should watch this video from Kurzgezagt video about it called You Are Not Where You Think You Are about this idea, it’s great!
This one was a surprise to me, Boolean (as in logic/algebra) is actually named after George Bool.
Well 5ghz requires more power, has less range, and needs its own antenna so for microcontrollers this makes it pretty pointless for devices that need range and low bandwidth for sending sensor updates, especially those that are battery powered. 5ghz can also have its own issues in cities if you have a lot of use of the DFS bands as well as being worse at traversing reinforced concrete.
Also, a 2.4ghz radio can also sometimes support other things like zigbee, BT, and BLE which can be used for other functions.
For what it’s worth, I have probably 50 WiFi devices and the majority of them are 2.4ghz sensors or switches and other low bandwidth tasks and I don’t have any issues, even when living in an apartment complex. If you are having issues you might need different hardware or more access points or something.
Anyway, all that to say that 2.4ghz definitely still has a lot of utility today.
So I stared at this for a while, particularly the pattern of the seam, I have a few questions. What type of infill are you using? how many outer wall loops? How much infill overlap (or whatever it is called)?
Also what happens if you rotate the part on the bed 90 degrees so the seam is on a different axis? Or maybe 45 degrees? This will make sure it’s not some sort of mechanical issue in one direct that shows up in this specific situation.
I know that all seems random but those are what I would check hah.
I think what that person is saying is that in your example the left part would probably be more durable because it is flexible and that the part on the right is less durable but more rigid, basically saying your result is expected and makes sense if you are wanting durability over rigidity.
I think that the part that is unclear is that OP is using durability, rigidity, and strength as they are defined by material science not in common English and they way they differ in definition makes that comment make sense. I’m not a material scientist though so I could be wrong.
I hope that is correct and makes sense hah!
Make sure your filament roller doesn’t have too much resistance as well. Since TPU stretches linearly way more than any other filament if it does have a lot of resistance then the extruder won’t be able to pull more filament until it overcomes that resistance and the stretch and it ends up physically thinning out the filament. Just a thought, hope it helps!
I agree with the other poster, this is wild. It seems like It is limited to one axis so maybe it’s a slicer or printer bug. Does it do it if you print it out of PLA? PETG is cranky all around but I have never had it do something like that hah. Is this part online somewhere? I can try to slice it and see what happens on my x1, I’m curious now haha.
ETA: you should also open a support ticket, they have great suggestions sometimes.
Oh man RDREs are so cool! the other commenter explained it better than I ever could but also here are some great videos about it for further fun!
ETA: I forgot the coolest one! NASA’s own test video
They also make this one which uses a CM4 but you can control 4 machines! I have been eying it now that I can get CM4s again, thanks for the post!
Yep definitely agree with all of this here, my friends and I have been saying the same things about Prusa too, they need to innovate or drop their prices in 2024.
I am also a big oss supporter but the user experience of the Bambu ecosystem is really great, lately it has basically become the same argument as iPhone vs Android.
To sum it up, I usually tell people that while both work, if your interest in the hobby is in the things that come off the printer then get a Bambu, if your interest is in tinkering and optimizing the printer then get a Prusa or something.
I have a mk3s that is modded and an X1C and I always reach for the X1 because prints basically always work in any material without changing settings beyond infill/strength etc, I don’t even calibrate anything on it anymore, their auto calibrate function is extremely good and I have used it with PLA,PETG,ASA,ABS, PA/Nylon, PC, PLA/PETG/PA-CF, PLA+wood, and even TPU. The Prusa does well but it is definitely more finicky but I’m definitely a core-xy convert now so my next printer will be a core-xy because the accuracy is so much better for tall and square objects especially.
Do you want to not use your DL380? IF no it might make a good moonlight host!
Yeah I’m with you, I read most of it but I just don’t know where the disdain comes from. At most scales of infrastructure anymore you can use them interchangeably because the difference is immaterial in practical applications.
Like if I am going to provision 2TB I don’t really care if it’s 2000 or 2048GB, I’ll be resizing it when it gets to 1800 either way, and if I needed to actually store 2TB I would create a 3TB volume, storage is cheap and my time calculating the difference is not.
Wait until you learn about how different fields use different precision levels of pi.
