One of the latest Prusa printer is closed source If I remember correctly Core xy
You are not completely wrong, they have one printer with closed sources.
This is mainly because consumer 3d printer have been developped by 3d printing enthusiast first and not a company, Prusa which was leader for some time used a lot of open sources project to build their printers. As it's getting mainstream as time goes by more and more companies shows up with closed sources project sadly.
Garage ain't good for printer, cold and humidity don't mix well with 3d printing, your clogging could also come from the warp issue as print goes up, nozzle dive into printing area, it's not able to extrude properly so melting plastic goes up and you get a clog.
Ringing is an artifact, which can be cause by speed, belt not tightened correctly, frame assembly. If everything seems to be correct, then you might look to see if your printer supports other firmware (some of them can help to reduce/eliminate it) https://cdn.shopify.com/s/files/1/0245/5519/2380/files/3d-print-ghosting.png?v=1681176108
See how the X seems to echo on the print
I don't have this printer and those issues can come from different problems so hard to tell like this.
Warping may cause layer issues as seen on pictures, stabilising bed temperature could help using an enclosure or maybe by putting your printer elsewhere, especially if it's close to a colder spot in your house. If the layer issues we see on that picture still there when there is no warping, then reduce speed as it goes up. Tall print will tend to wobble more, which can make nozzle hit print, also nozzle path will not be as accurate after some traveling which can end up with similar layer issues.
About your clogging issue, what temp (bed and nozzle) do you use for pla?
You also have a ringing issue
I prefer other kind of story, which represents more the history and ethics of 3d printing https://enablingthefuture.org/
Fuck profit, helping each other is what we need for a bright future.
If you keep a low infill, top/bottom layers will be rapidly more efficient but will cost more time and material than infill. The amount of wall is also to take into account. Few years back, I remember a test video showing that wall number were actually more efficient than infill. But depending how the test is being done, this might change.
It is mostly targeting french content (RD is a french company), so most user may have not see a big change. For french, RD has become muche less attractive because RD has banned biggest french torrent site and 1fichier files are scanned, if file matches hash content from movies/series it will blocked download.
And if that's doesn't work, message me and we will try to solve this out
Have you tried a Factory reset?
No, there isn't aac video . Your post mixed up, You are confusing audio and video codec and don't give any details for people to help you out. Instead of ranting, ask for help with details (we are not on Reddit)
