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 {

There are no updates available via sudo apt update && apt upgrade as of time of this post, and this is from an xorg session.

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?
