Thanks everyone. I raised the initial temp by 5 degree, and reduced the z-offset by 0.05mm. It looks great now

it is printing the fidget star now. Note, that each star has a thickness of 2 walls. The 1 corner is a little bad, because i took to much to time adjust the z-offset.

Try increasing hotend temp for first few layers and hotbed temp throughout

the default from the printer was 60C. I had some better results with 70C. But the issue still happend with more delicate prints.

those PEI sheets usually need higher bed temp than the regular sheets

thanks. I didn’t know that. What magnitude are we talking here (like: 10K more for PEI-sheets? or more like 1K?)

Try moving z closer for first layer

I think this may be the solution. How much should I change the z-offset? (the print in the video has 0.2mm layer height. And the worst-adhession issues happened with 0.1mm)

I like that idea. I haven’t even thought in that direction.

By how much should I change the offset? The print in the video has 0.2mm layerheight. But the worst results (i.e. total print failur) happened with 0.1mm.

evolution could happen in jumps. How often that happens is debatable.

I use UK-Layout, with some remappings for my precious umlauts

q+altgr ->ü
a+altgr -> ä
s+altgr -> ß
z+algr -> ö

bonus: in contrast to the peasentry I have an uppercase ẞ (altgr+shift+s)

As opposed to Threads stealing all brands companies and users anyway?

The extend-phase is when people migrate to threads, who would have stayed otherwise.

the general strategie is called “embrace, extend, extinguish”. This strat is the reason, why everyone uses MS Office today

Interesting how college ruined your love for programming

it was probably the general pressure and depression.

and work got it back

the costumers and the colleague were nice people. I enjoyed solving actual real-life problems.

Studying Computer Science constantly fed me with new interesting ideas, and I still had more time to play around with those ideas.

after my first job, I went back to college (uni?) to get my masters. There I had lots of fun implementing some of the theoretical stuff.

what kind of projects or whatever can i do to have fun again without feeling stressed.

• Write programs that scratch your own itch.
• write bots for communities you care about.
• write userscripts/browserextentions
• do programming/hacking challenges

(for stuff that is always online, like a bot, or a webservice, I recommend getting a dedicated computer, like a raspberry pi or a small vps)

also some general recommendation

• keep you goals small and tangible. If a thing takes more than one sitting to complete, it will add to your stress when you add the remainder to your todo list.
• do the simplest thing, that could possibly work.
• when doing new stuff, use chatgpt to come up with a plan/boilerplate/demo/2nd opinion.

from personal experience: before I went to college, I had lots of fun doing programming challenges. During college I lost all interest in programming. At my first real job, I regained my love for programming, when I started programming things, that actual people need to improve their daily work. Since then I enjoy programming for work, as well as in my free time.

how they fool the AI while keeping it invisible to the human eye

My guess is that AI companies will try to scrape as much as possible without a human ever looking at the data.

When poisoned data start to become enough of a problem, that humans have to look over very sample, then this would increase training cost to to a point where it’s no longer worth to bother with it in the first place.
