This is a Prusa MINI+ that has worked flawlessly for 3 months. Suddenly the prints won't stick to the bed, the first layer is all messy and I cancel the print before anything worse happens.

• The printer has auto bed leveling so I would rule that out.
• The plate is cleaned with 70% IPA, so it's not dirty either.
• I have tried to adjust the "Live Z Adjust" while printing that first layer, but no setting works well.
• Each filament is printed at recommended temps (+/- 215C) and bed is at 60C.
• Out of my 5 spools, only 1 works well: RepRapper 3-color PLA. Even the Prusament PLA fails to stick well, and also eSun PLA+, and eSun matte PLA, and Tinmorry TPU.

Update:

• Thank you all for your kind input.
• I washed the plate, and cleaned the nozzle (have no spare nozzle).
• I also did a fresh Z-test (with this object) using Prusament galaxy silver PLA.
• That was successful and showed that my height was already very close to perfect.
• Z-test result shows that -1.425 is best. I was off by only 0.025. Image
• Started printing an object with eSun matte black PLA but the result was same as in my original photo.
• Changed back to the Prusament galaxy silver PLA and the result is perfect. (image)

So it looks like my filament storage is not up to snuff! Good thing that I only have a few spools, so not much is lost.

Let's say I never want to see another post about Trump, or NFL, or Apple, or that weird "rule" thing.

Is there presently any way to filter that out? In Lemmy as a whole? Or inside the Voyager app?

I am looking for an action cam. It does not need to be a GoPro or DJI simply because they are so very expensive -- but finding alternatives is difficult, mostly because all those products are misrepresented on sites like Amazon. Some reviews reveal that the manufacturer offers free add-ons to customers who post 5-star reviews. That means I cannot trust any review at all.

Where can I find honest reviews? How can I choose a decent action cam without getting scammed?

Printing here with eSun PLA at 215 C on a Prusa Mini, and there are lots of hairline strings.

What's causing those strings? Temp too low?

TLDR = what's a good next step after kid-friendly 3d creation tools?
Solved = Fusion360 is voted as winner, we even got a nice tutorial playlist.

Hi all - I'm still very much a new user. Highly skilled in IT but just getting my feet wet in 3D printing, since a month or so. I love the possibilities! I can physically create anything I can image, it's amazing.

So far, I've used mostly TinkerCad and done lots with it. The learning curve is practically non-existent, and it has sufficient features to do a lot.

But of course it's not perfect. Obvious example: can't do fillets, except in roundabout ways using negative blocks.

I've tried OnShape, OpenScad, Fusion 360, but found them quite a steep hill to climb.

Are these good choices, or is there something in-between that would make it easier for me to advance?

First, apologies if this isn't the best community; please direct me to a better venue if so.

TLDR: I need to buy 2× used gaming laptops that are powerful enough for 3D-heavy games -- I don't know what to look for?

Situation:
My kids have used Lenovo laptops for their rooms, and after some years, their gaming choices (BeamNG and other such 3D-heavy games) mean that old business laptops won't cut it. They need to be replaced (the laptops, not the kids!).

Problem:
Back when I was young, I understood CPU and GPU requirements - these days I don't. Help!

• An Intel i7 may be great but it may also be several years old. I don't understand the naming anymore.
• Most normal laptops have integrated graphics which don't satisfy even most basic GPU requirements.
• Real "gaming laptops" are expensive! And I need 2 of them! Gotta find something used, and I have no idea what search criteria to set.

My printer (well, PrusaSlicer) always starts with a line around the object I am printing. See (1) in the image. --Why? What does that do?

There is also this line (2) at the front of the bed. --Why? What does that do?

Here's a part of a cabinet in my wardrobe where my printer lives. It's a bit noisy with all those hard surfaces so I am just about to put up some foam padding on all 5 sides.

Is that stupidly dangerous?

You can see I have a smoke alarm there, but it won't stop a fire on its own.

Edit: the cabinet has no door, it's always open like in the photo, but the wardrobe door is generally closed. The room has some ventilation so smells do go away.

Background:

• At work we use MS Office, because who doesn't. We used to have a central file server with lots of well sorted directories.
• Then Corporate decided to ditch that, everything must move into OneDrive so there's always a Data Owner.
• The local boss had to move everything from the network share into his own OneDrive, and then share, with each of us, the folders that were relevant to each of us.
• This sounds like distributed storage, which is probably smart in some way.

In reality, it's shit. Everything is now a link to "corporateName.sharepoint.com" in the browser, and it's a hassle to find that in the file explorer. SOmeone just shared a folder with me. I see it in my browser. How do I get it from the browser into a normal folder view? Should I forget about on-disk storage; is everything today just a browser bookmark?

Worse, I have no idea what's where. Some people share some stuff and somehow it ends up in my OneDrive, but what's the context of it?

This seems so wrong to me. Am I just not "getting" it??

Hi all, I'm not sure what to do here. The controllers vibrate extremely loudly, it sounds like I am shaving my face! I don't remember it being so loud when the thing was new, just two months ago.

Is it defective?

What's the best way to get warranty replacement? I got it from Amazon but the only course of action there is to send in the whole thing for repair. Is that the best choice?

TLDR:

• Update: the server software has a bug about generating+saving certificates. Bug has been reported; as a workaround I added the local IP to my local 'hosts' file so I can continue (but that does not solve it of course).
• I suspect there's a problem with running two servers off the same IP address, each with their own DNS name?

Problem:

• When I enter https://my.domain.abc into Firefox, I get an error ERR_SSL_UNRECOGNIZED_NAME_ALERT instead of seeing the site.

Context:

• I have a static public IP address, and a Unifi gateway that directs the ports 80,443 to my server at 192.168.1.10 where Nginx Proxy Manager is running as a Docker container. This also gives me a _Let's Encrypt certificate.
• I use Cloudflare and have a domain foo.abc pointed to my static public IP address. This domain works, and also a number of subdomains with various Docker services.
• I have now set up a second server running yunohost. I can access this on my local LAN at https://192.168.1.14.
• This yunohost is set up with a DynDNS xyz.nohost.me. The current certificate is self-signed.
• Certain other ports that yunohost wants (22,25,587,993,5222,5269) are also routed directly to 192.168.1.14 by the gateway mentioned above.
• All of the above context is OK. Yunohost diagnostics says that DNS records are correctly configured for this domain. Everything is great (except reverse DNS lookup which is only relevant for outgoing email).

Before getting a proper certificate for the yunohost server and its domain, I need to make the yunohost reachable at all, and I don't see what I am missing.

What am I missing?
