if your axioms support multiplication you’ll get division out of them for free

this is true... except when it isn't.

In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist

semi-related: would it count as piracy, if you reconstruct the 3d model from the 2d promo-images?

this kinda looks like an AI-image gone wrong

if they would stop calling it vandalism, it would take away all the fun

is this true?

idk, maybe like a server for "-key"-derivates with a community for each individual derivate?

Some of these derivates will be hugh, but reddit-like sites can already deal with communities of vastly different sizes, so whatever i guess.

Dies sorgt für freude.

auf English sagt sie "This sparks joy". d.h. man könnte es wunderbar übersetzen mit "Dies entzündet Freude".

Aber im orginalen sagt sie "ときめく", was noch mal viel mehr übersetzung-potential bietet, siehe; https://jisho.org/search/tokimeku

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.

fyi: it does happen in nature https://en.wikipedia.org/wiki/Natural_nuclear_fission_reactor
