This seems to be an engineering sample CPU. Since these are pre-production, that could mean it's basically a fully functional CPU. It could also have serious issues.

Unfortunately, SawStart is one-use-only. Once started, the blade cannot be stopped, and must be replaced with a fresh blade while the running one is carefully disposed of.

Sure, the skull is biodegradable. But didn't you know that large-scale human farming is responsible for the vast majority of CO2 emissions?!

Double-check my first PC build (de.pcpartpicker.com)

My 5 year old notebook is starting to show it's age, so I want to finally build a "real" PC. I rarely play games, so this is probably overkill - But I don't want my PC to be what's stopping me. I also expect it to last a while.

I chose all AMD because I'm running linux, and AMD seems to still be the best choice for that.

I found a couple similar posts on which I based this list, so most of the parts are probably fine. I'm unsure about the cooler: How much headroom should I leave? This one is rated just 10W higher than the CPU TDP, so it might be cutting it too close.

It looks to me like a JST SH connector: https://www.sparkfun.com/products/retired/10357

Measure the distance between the two pins - if it is 1 mm, this is most likely the connector you're looking for.

Do you expect every meme to be meticulously handcrafted? It's a stupid joke, not a work of art.

My router is called Jupiter, everything connected to it is named after a moon. Callisto, Ganymede, Thelxinoe, Kallichore are what I'm currently using.

IIRC, this is actually done at some point in the books.

You can host a Firefox sync server yourself. You could run that on something like a Raspberry Pi in your local network. If you need remote access, use something like cloudflare tunnels (although I guess that's something else to be paranoid about).

Windows is clearly superior. If you've had enough of the settings app, you can just switch to the control center!

submitted 1 year ago* (last edited 1 year ago) by elDalvini@discuss.tchncs.de to c/3dprinting@lemmy.world

I built my 3D printer a couple of months ago, but I can't get it to print sharp corners. The corners in the picture should be 90°, without any fillets:

During this test print, I played with multiple parameters: speed, temperature, acceleration, junction deviation, linear advance. All of these were also individually tuned previously. Nothing seems to make a difference.

Could this be a issue with the construction of my printer? I'm beginning to think my hotend isn't rigid enough, but then I would at least expect better results at low speeds.

Edit: the printer is a CoreXY of my own design running Marlin 2.1.2.1. The Slicer is PrusaSlicer with most settings left as default (but increased speeds)

These brakes are single-pivot side-pull caliper brakes. They can work well, but only if they are well made - I personally never had much luck with Weinmann brakes.

For the rear brake, pretty much the only thing you can try is replacing the brake pads. The front ones don't look very worn, but the rubber gets hard with age and loses its effectiveness.

The front brake looks broken beyond repair. The part I circeled red should be attached to the green part, but the connecting part seems to have broken off. You might be able to find a replacement, but I would recommend replacing the whole brake for a better one.
