i've been battling this wrinkling phenomenon for weeks. it shows up at random, and i can't figure out what i'm doing wrong. i've changed layer height. i've checked the z-offset of the extruder. i've lowered acceleration to 1/10th of normal. i've lowered the flow rate. i've raised the flow rate. i've cleaned the plate with soapy water and IPA. i've checked for bumps on plate and the bed. i've flipped the plate over. i've done automatic and manual levelling. i've redone the bed compensation calibration like twelve times. i've moved and rotated my print. i've tried different colours, materials and makes. i've dried the filaments to under 10% humidity. i've switched extruders. i've placed the printer on a mass damper (a 25kg slab of concrete on top of a 2cm thick rubber granule mat). the last thing i did was physically holding on to the extruder as it moved (that's what that thicker band in the top left is).

this can happen no matter how far along the print i am. it can be fine for the first 300 layers, then start happening on layer 320 and be so serious that the extruder hits the wrinkles and loses its place on layer 330. i've been sitting there staring at the printer as it does it and the filament just seems to... come out like that. it doesn't expand or anything. and sometimes it doesn't happen at all. the only common denominator is that all the prints that it happens on have large horizontal planes.

i don't think this is caused by overextrusion of the first layer, partly because it never happens on the first layer, and partially because i did a bed adhesion test:

yeah adhesion is awful here. i forgot to actually clean the plate this time. but the part in the middle is the only one that matters, and that is clean. if anything that looks like underextrusion. i just don't understand. i think i need professional help. first from the 3d printing community, then from a therapist.

here's my bed compensation matrix, for reference:

i've started printing in petg with pla supports since the support surface finish is so good, but whenever i print round things with tree supports i see what looks like layer shifts. since my printer is a corexy toolchanger and not a bedslinger this behaviour has confounded me until today, when i happened to look at the right time. it seems that the layers of the perimeter are not adhering properly, and as the filament cools it contracts, catches on support material, and pulls the entire ring off of the pla supports. meanwhile on the middle part i see no issues at all.

i don't even know what to call this problem. it's not stringing, it's already extruded plastic that does it. layer adhesion issues maybe? the photo up top is a reconstruction of how this print looked on the bed, since it fell apart the moment i flexed the buildplate.

here's a look at the underside of the pieces:

and a closeup of the round part:

as far as i can tell, that's pretty much perfect before it falls apart.

i can still print with the "normal" supports because they come up the sides of the circle, but it feels like a waste of filament. any ideas?

six months after my last workplace went bankrupt, i'm out again. an international consultancy firm took me and all my colleagues in from the failing business and we got raises and bonuses... and now i've been let go. only me.

they've not managed to sell my skills anywhere for six months, so the decision makes economic sense, but... that just makes me feel useless. evidently the local office feels bad because they decided to pay out this month's salary in full, but that doesn't really help with the self-esteem.

after all the shakiness of the bankruptcy and being lied to about great numbers leading up to it, i just wanted some stability. but fuck me i guess.

...so how's your day?

ringtones were big there for a while, but now it seems everyone just leaves them on default.

i finally received my crowdfunded copy of Earthborne Rangers, which due to its environmentally friendly goal, made all their cards without the plastic core cards usually have in order to spare the environment. they're all floppy and fragile, so they definitely need sleeves. only... there's around 1300 cards.

buying cheap card sleeves from china would run me around €16 plus import duty, but all the ones i can find in local stores are like €5 for 100... that's a lot of money. and i don't even know where those are produced.

so, any recommendations on where to get sleeves? preferably with some rigidity if that's a thing that exists? i think the cards are like 88x63mm.

Edit:

Turns out Arcane Tinmen, from Denmark, make some of their sleeves in-house! so Dragonshield sleeves are indeed european, except the really cheap ones.

Growing up, portable cassette players were always called "freestyles" here. I never knew it was a marketing thing, or that some other countries also objected to the naming.

this is "original research", which means i dicked around on the internet archive for half an hour. it may be wrong.

i love all these little diorama creators that have popped up recently, they make it very easy to create a city that looks good. But they only hold my interest for so long. i'm looking for something with more meat on it. Any recommendations?

as an example, i remember the first time i managed to keep a city of over a million people going in Sim City 4. at this point money was tight, so the building aspect took a back seat to actually managing the city. balancing the budget, fixing congestion, and so on. it was great fun and a very different challenge than i thought i was in for.

most citybuilders these days seem more focused on the building than the older ones. for example, when i got to the point in Cities Skylines where i thought i was entering the "management" phase, i unlocked a building that just removed an aspect of the game. it was like the game thought that planning the electric grid or schools was a chore that got in the way of building a city, and as a reward it removed those chores.

basically, i'm looking for a game where rather than physically growing the city through placing individual buildings, i help the city grow. like transport tycoon, except the city is the focus rather than the interconnections.

a key part of this, i think, is time. a city that is frozen in time and where clicking with a tool just builds things, like C:S or SC2013, doesn't make for interesting growth. a city designed around historical limitations feels more like something that needs to be managed. a game where buildings and roads take time to complete and modify requires more forethought.

workers and resources comes pretty close but the central planning aspect means that i still need to micromanage the buildings. if it was all about zoning, with special buildings being unlocked by the request system in older sim cities ("x seeks permission to build a stink generator downwind of your residential area") i would enjoy it more.

I have two monitors, one 1440x3440 and one 1080x1920 to its right. Every boot, the desktop on my left monitor moves over and displays on top of the right one. Killing and restarting plasmashell moves it to where it should be, but i'd love to fix this without adding that to my .xsession. Thing is, i'm not versed enough in the KDE internals to know where this issue even stems from.

I'm running EndeavourOS with Plasma 6.1.5 on X11. I haven't tried wayland since Plasma 6 switched to it and then promptly flickered itself into a crash.

Edit: This machine runs the amdgpu-pro driver, and has done since before plasma 6 released. i didn't have this problem on plasma 5.
