It’s a myth that capricorn tubing is better in any way

I’d call it “successful marketing” :) But yeah, they’re really managed to convince a lot of people that it has near magical properties, and I’ve seen a lot of random people recommend it to others for all sorts of issues.

It sounds like bed adhesion might have got worse, perhaps you have touched the print surface with your fingers while removing prints? You could try removing the plate and washing it with warm water and soap. Some people use IPA but if you do then you need to make sure you really wipe it clean before it evaporates, otherwise the dissolved fats will stay on the bed. If your bed has some kind of anti-stick coating I think there’s also a risk that you damage if you use stronger solvents.

As for warping in general it could be an indication that your flow rate is exceeding your melting capacity. If you have an all metal hotend you could try printing at higher temp, if not then try reducing print speed instead.

Ahh, I thought you meant you had a 0.2mm nozzle, but now I see you probably meant layer height.

Moisture absorbtion is rarely a problem with PLA, but hopefully dehydration won’t hurt, as long as you don’t accidentally overheat it and it deforms. I’ve left rolls of PLA out in the open for 6 months without noticing any deterioration. Both your filaments used to print fine, and then the oozing spontaneously started with both of them?

2mm retraction should be more than enough for a direct drive extruder.

What filament and other slicer settings? Could be too hot. Could be retraction settings. Did the oozing start when you switched nozzles? If it’s a cheap Amazon nozzle it might be faulty and have a different diameter than advertised. Did you follow the correct procedure with hot tightening when switching nozzles? If not, you might have got molten filament in between the nozzle and the heat break.

Assuming they already own a PC, if someone buys two 3090 for it they’ll probably also have to upgrade their PSU so that might be worth including in the budget. But it’s definitely a relatively low cost way to get more VRAM, there are people who run 3 or 4 RTX3090 too.

The only issue is (layer height), which of course can change from print to print.

Technically not the only issue 😀 it can also change from layer to layer.

Maybe calculate it from the length of filament being pushed out / the length of the movement * filament cross section? I’m on my phone so I can’t check right now but that info should be possible to extract from the gcode iirc

Never heard of this printer brand, but if it turns out that its mainboard isn’t compatible with what you’re trying to do then it might be an option to replace it with a cheap stepper driver board from AliExpress. You wouldn’t need anything fancy if you’re running Klipper on your RPi

For LLMs it entirely depends on what size models you want to use and how fast you want it to run. Since there’s diminishing returns to increasing model sizes, i.e. a 14B model isn’t twice as good as a 7B model, the best bang for the buck will be achieved with the smallest model you think has acceptable quality. And if you think generation speeds of around 1 token/second are acceptable, you’ll probably get more value for money using partial offloading.

If your answer is “I don’t know what models I want to run” then a second-hand RTX3090 is probably your best bet. If you want to run larger models, building a rig with multiple (used) RTX3090 is probably still the cheapest way to do it.

No and I hate it :( Even if there are a few legit review sites still around it’s near impossible to find them among all the fake reviews being pushed by search engines

Perhaps not helpful for most people, but Add:North offers recycling for PLA which you have bought from them.

MyTechFun also has a lot of material tests, and while perhaps not ideal from a usability standpoint he posts detailed Excel sheets with all the data.

Blog post with the same info, for people who don’t like watching videos.

So it’s supposed to be 15 hours/month included with your premium subscription? Since I’m not familiar with how Spotify audio books work, I thought you meant that you had a free account and was allowed to listen 15 hours to books that would be included/unlimited with a premium subscription. Contact support if it ate through your monthly credits faster that it should. If you’re a paying customer supports are usually quite helpful.

I’ve been using Intel NUCs, even though they have a lot of issues and start failing after about 3 years of heavy use. Previously used Kodi on Arch, but with the latest NUC I decided to go with Xubuntu and for some reason video playback doesn’t work in Kodi now. So instead I just use VLC media player for TV/movies and a web browser for everything else. Got a Logitech K400 Plus wireless keyboard which makes it easy to control the computer from the couch.

I agree with half your statement :) There are other cheap brands that are just as bad as Creality, or possibly even worse.

From what I’ve heard Microcenter frequently has a deal for “new customers” where you can get an Ender 3 Pro for $99. Though it’s a pretty old printer by now, and while getting some mods would do a lot for it, I think I would rather get something like a Sovol SV06 unless $200 is a hard limit.

Any possibility that you’ve accidentally modified something in the automatically generated part of the config, so its failing to read the saved value? Perhaps you could attach your entire printer.cfg?

Based on the comments here, it sounds like you and others agree that the majority of people who responded to your initial post didn’t do anything wrong, but you thought the overall experience was negative due to a few mean comments, right? So with this meme post, you portray the entire community as a bloodthirsty mob who got angry at you for asking a question. Do you see how this could be considered “not nice” to the people who wrote helpful comments, those who downvoted the negative comments, and people who didn’t even see your post but are still included in the ergo mech community here? While those who wrote mean comments to your post should consider being kinder to newbies, perhaps you ought to consider being kinder to everybody else.

There are tons of options for running LLMs locally nowadays, though none come close to GPT4 or Claude 2 etc. One place to start is /c/localllama@sh.itjust.works
