Hi all, I've been running the latest Pop_OS 22.04 LTS, and recently discovered all the new cosmic apps from the upcoming Cosmic DE. They are seriously impressive in both UI/UX and performance, but I got updates to all of the cosmic apps yesterday, and now when i try and launch any of them, they simply hard lock my computer, forcing a hard reboot to recover.

I noticed a few recent reports of similar behavior over on Reddit, but Reddit 'tis a silly place, so I'm posting to Lemmy instead.

Since I cannot copy/paste any errors, i took a picture and hand typed out what happens when i launch cosmic-store from a terminal. It appears to be a json-ish error.

ERROR winit::platform_impl::platform] X11 error: XError { description: "BadMatch (invalid parameter attributes)", error_code: 8, request_code: 149, minor_code: 4 ) os info: ```sh kernel: 6.9.3-76060903-generic

distro: DISTRIB_ID=Pop DISTRIB_RELEASE=22.04 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="Pop!_OS 22.04 LTS" ```

There are no updates available via sudo apt update && apt upgrade as of time of this post, and this is from an xorg session. ```sh ~$ ps -e | grep -E '(Xorg|wayland)'

Does anyone know if there's a way to launch f launcher instead of the shitty Google home screen when the unit resumes from sleep? I essentially want to make it where I never ever see the Google home screen ever

Just thought I would quickly share what can happen if you're not paying attention with a heavy mass spool if you're not careful. I have all my spools on a dowel rod attached to the top of my printer enclosure and fed through an opening in the top. Never had the slightest issue with 1 kg spools, and I thought I would save a little bit of money and time changing filament by trying a 3 kg spool. It spins perfectly fine without friction, but the much heavier mass is enough to cause it to have significant strain on the extruder pulling it in to the hot end. You can see in the result where I provided strain relief by hand while watching it print. !

In the span of 2 days, I've managed to break the E string on two of main jam guitars. Bad luck, or bad technique? I'm betting on the latter lol

Spotted this in a store today and promptly put my shit that I didn't need back on the shelf and walked out.

Edit: it has been pointed out this sign is most likely ironic, in line with the companies schtick. I would counter that while that may be true, behind every good joke is a little bit of the truth. They mean this unironically also.

Hi everyone - I'm doing some prototyping on a part I'm designing. The final part will take up nearly the entire build plate, but for a test print, I'm using a negative modifier to remove 80% of the part, leaving only a sliver to print. The problem is that once sliced, the part left to be printed is way over on the edge of the build plate, and I'd rather it be in the center if possible. If I position it where the edge i want printed is in the middle, it of course complains that part of the file is off the build plate and won't let me slice, even though it's all being removed with the negative modifier. Any ideas on how to get it to cut the piece and still center it?

All the sanding blocks I have seen are the nut and bolt type, but i found myself wanting something more of just a ... block. No adjusting, loosening, tightening, moving, just wrap your sandpaper around an edge and go. So I spent 15 minutes in FreeCAD and made one. So far it's working great.

In case anyone else wants it, or has feedback. https://www.printables.com/model/762884-simple-sanding-block

I won't profess to be a design mastermind, but it was a fun process. I learned a lot and it was a lot of fun.

I'm contemplating a Prusa MK4 + official enclosure and I'm looking at the way the enclosure handles filament feeding into the (N)extruder. Normally, filament is loaded directly from the spool into the extruder, but with the official enclosure, I see it's fed through a PTFE tube and coupler. It seems to me this would make changing filaments mid print quite a pain. Would I be ok simply feeding the filament into a PTFE tube, but cutting it way short of the extruder and simply feeding it in from there into the extruder without the tube?

Hi all, I have a quick question about my z screw coupler (as i understand it, the metal cylinder at the bottom you can manually move your z axis up and down with).

When I manually raise the z axis (with steppers disabled) by rotating the coupler clockwise, after I let it go, it reverses it's rotation on it's own and sinks back down. This is frustrating because it takes forever to actually move it any distance. Am i doing anything wrong? Should you only ever move the z axis with software, and if so, is there a way to fix the issue of it going back down? I don't know how to adjust the tightness of this part, I'm still pretty new.

I still have no idea what I'm doing really. Just too determined to give up I guess, and it's been such fun. Anyway I made a guitar pedal light switch cover. Still a lot of work to do, and every time I look at FreeCAD the wrong way, the model breaks, but it's been a fun experience nonetheless.

On a side note, anybody have any idea why the face of the model is rough textured, while the foot switch on the lower half is flawless?

Good morning friends! I'm still fairly new to 3D printing, although I'm learning a lot more to be dangerous now. I'm printing this part, and I have cleaned and leveled the bed, as I do before every print, and usually have very few issues. This time, my first layer went down almost perfect, with the exception of the bottom right corner being a little bit tight, but as you can see in the picture, every once in a while, I get exactly one line of it not adhering on the first layer. Subsequent layers all seem to lay down perfectly fine, so I'm suspecting bed adhesion, it's just weird that it's only in one single line. Anyone ever experienced issues like this, and seen a remedy?

I'm a beginner 3D printing novice. I have done about 5-6 successful prints so far, and my last two have technically come out fine, but they seem very brittle. By brittle, i mean that both prints have snapped cleanly into several pieces, not by design. My extremely novice research has led me to think it's a layer adhesion issue - it is very cold here where I am right now, and I print in a non-climate controlled shed because of reasons. I do have an enclosure though, so i tried printing my PLA at 205 instead of 200, but same result. Is there a better way to correct prints snapping apart like that? I don't feel like i used any excessive force.

Ender 3 Pro Polymaker dual matte white/black PLA 1.75mm

I'm getting into 3D printing, and due to the nature of my living constraints, I find myself with a large 12 ft x 20 ft non-climate controlled but clean shed from which to print. I bought one of these small microenvironment enclosures for my ender 3 pro, but temperatures here in the winter can reach the teens, and summers over 100 Fahrenheit. I guess my question is how much temperature can those micro enclosures account for when it's extremely cold on the outside?

Hello community, I'll try to be brief. My 13 year old son got a 3d printer as a gift, and I'd like to learn alongside him. We have 0 experience. However, I am a data scientist, so lots of professional Python experience, if that helps. We're a foss/Linux family so my questions are:

What tools are the best to learn for 3d printing for me? I am ready to learn CAD programming. Can you all recommend a tech stack and resources to learn it?

I was very confused until I realized a comment I read was from someone with my username, but registered to a different Lemmy instance. By identifies, I mean the username is highlighted and the blue avatar indicating it's me is present. Also, this doesn't feel like the best place to report bugs, is there a better way?

I'm looking at making a fun project for generating media recommendations based on past viewing behavior and I'd like to know if the API exposes something like "previous N items that user X played"

Looking through the swagger docs on my server, i see an endpoint of /Users/{UserID}/Views but that only seems to return all of my libraries, not the individual media for that given user's playback history. I'd like to get the last X (configurable) items that a given user Id has played, but no luck so far.

I'm using the python library here

After 7 long, agonizing months waiting, I got my PJD Woodford Elite today! It's a custom design, which Leigh at PJD was very gracious to allow me to choose

Stats:

• Color: Highland Purple, quilted
• Fretboard: Roasted birdseye maple
• Pickups: Cream T P90s

It sounds so amazing, i legit teared up when i first plugged it in - think Strat but on steroids. I immediately gravitated towards Andy Timmons, so I had to try a bit of Electric Gypsy, through my Quad Cortex Mesa Lonestar preset, and it nailed it.

So happy today!!

In his sleevies.

I know this is going to sound like some clickbait bullshit title, but I'm genuinely curious, asking in good faith. My two oldest sons are enamored with him, and he seems like a genuine guy, so I'm asking - is he a nice guy? If you google the question, you get a bunch of reddit hate, which I don't always trust, because...it's reddit. I have not watched much content (not my thing, I'm old) but I'm just curious what the fediverse has to say.
