I'm printing some Gridfinity bins for some drawers, and one of them needs to be quite tall to fulfill its purpose (18u, ~130mm). I took a shortcut and generated one from this generator using the default wall thickness and printed using Prusament PLA. This resulted in the walls falling in on itself, and my second failed print.

In hindsight, considering the wall thickness of 0.95 mm, this seems pretty obvious to me now. I want to give it a second go, but beef up the wall thickness and make sure there's some proper infill between the outer walls to keep it stiff.

At the same time I don't want to waste too much filament, so I want to hit a sweet spot of sufficiently thin walls and sufficiently low infill percentage, while avoiding another failed print.

Anyone have good experience with these kinds of prints that could give some input on a rough estimate for what I should aim for here?

I am using Adaptive Cubic infill by the way, but for no other reason than that has become my default infill pattern after some previous suggestions made here.

I work in a corporation with an IT-department that is all in on whatever Microsoft is offering. My team has for some time gotten more and more autonomy in tooling as IT is overloaded and forced to relinquish some control, but we still rely on them for supplying compliant machines that have access to our resources.

I requested a Linux machine just over 5 months ago, and I finally got it this week. It is running Ubuntu with GNOME, not my first choice, but the only thing that is Microsoft Intune compliant as far as I know.

So far it is such a relief. A better specced machine with less bloat running on it. It should be far between any OOM-issue I get now... Slightly annoying having to use Edge for any service requiring corporate SSO, but I'll swallow that pill...

I am currently looking into getting a keyboard to use in jamming sessions. I have so far been partial to Roland GO:KEYS 5 (this over the 3 due to the additional inputs and an acceptable imo price difference). This (around 500 EUR) is around the max I want to give for it.

But, as far as I can tell, it does not have a proper loop function. It has a layered recording-function, but this would require me to play through the full song.

So I have two questions:

1. Are there any keyboards anyone of you would recommend in roughly the same price range that has a looper?

2. Could I use my Boss RC-5 for this, plug the keyboard into input A and plug it back into the keyboard from output A? I would like to avoid buying a new speaker for this, and tge loop pedal would also be connected to my guitar and to the amp.

I got a Prusa CORE One earlier this year, and so far I've been very happy. I have not ventured outside of the default settings though, and I use their own filament (only PLA). This has worked perfectly fine so far, but now I ran into an issue, and I figure it's time to come out of the "default settings"-bubble and learn some more about this stuff.

I am trying to print a Gridfinity holder for a rolling pin, so I tried to cut out a appropriately sized cylinder in a template with a boolean operator in Blender. When the print got to the concave portion, the print started to fail - uncertain how to best explain it, but the overhangs over the infill did not properly bridge and the filament started to warp so that the print head would hit it on the next pass (and make some nasty scratching sounds). I stopped the print when I noticed this. See an image here:

I am uncertain whether this is due to the model being poorly optimized for 3D-printing, if the printer settings for the filament were off or if I could've tweaked the slicing settings to achieve a better result.

Is it obvious, looking at the image, what the primary reason for this failure is?

Note: I've ended up printing this again already with a regular rectangular cutout instead of a cylindrical one, so I am just trying to learn more about what made this fail to learn more.

I am looking into getting a BOSS RC-5 looping pedal for my guitar, and I am curious if anyone has any experience with using it with Linux?

It makes use of this BOSS Tone Studio to allow adding additional backing tracks, but it is only officially supported for Windows and macOS. I could not find many examples of people using it on Linux, but for the most part any discussion I could find was in the context of their amplifiers.

I wonder if it should be straightforward to run it through Wine? As far as I can tell, you only need to set it up as a storage medium and connect it to your machine, although you can't just drag the files directly onto it.

It is not a deal breaker for me if I can't get it working, but it would certainly be a benefit if I could.

Recently at work I've been thrown into running some Python scripts in a Docker container (all previous Docker-experience is limited to pulling images from container registries to host some stuff at home). It's a fairly simple script, but I want to do two things simultaneously that I have so far been unable to accomplish: redirecting some prints to a file while also allowing the script to run a cleanup process when it gets a SIGTERM. I'm posting this here because I think this is mainly signal handling thing in Linux, but maybe it's more Docker specific (or even Docker Swarm)?

I'm not on my work computer now, but the entrypoint in the Dockerfile is basically something like this:

ENTRYPOINT ['/bin/bash', '-c', 'python', 'my_script.py', '|', 'tee', 'some_file.txt']

Once I started piping, the signal handling in my script stopped working when the containers were shut down. If I understood it correctly it's because tee becomes the main process (or at least the main child of the main process which is bash?) and Python is deferred to the background and thus never gets the signal to terminate gracefully. But surely there must be some elegant way to make sure it also gets it?

And yes, I understand I can rewrite my script to handle this directly, and that is my plan for work tomorrow, but I want to understand this better to broaden my Linux-knowledge. But my head was spinning after reading up on this (I got lost at trap), and I was hoping someone here had a succinct explanation on what is going on under the hood here?

Sad news - I have been very happy with CalyxOS, and not sure if I would want to continue using it without security updates or move to another ROM on my Fairphone 4. It seems perhaps that I would anyway need to reflash when they get to the point of resuming updates? Anyone get a clearer reading on that than me?

I have been contemplating trying out Ubuntu Touch which has according to their site 100% compatability with Fairphone 4 now, but there are some functionality that I think would struggle without, and if I can't get it working as I want, I wouldn't be able to reflash CalyxOS now. Getting a new phone to install GrapheneOS is not an option for me.

What are other people here using CalyxOS going to do to maintain a modicum of privacy on their mobile devices?

I am contemplating getting a stand mixer for baking purposes, and I've always known KitchenAid as the default choice here. I would instead want something European-made, but I am unfamiliar with the landscape.

Do any of you have any experience with European models, such as the Ankarsum or Bosch OptiMUM (what kind of name is that??), or any other?

I have a good food processor and blender from before, so I don't need it to be able to handle all kinds of things that stand mixers are not meant for, but if there's some extensibility beyond just kneading that I wouldn't otherwise be able to achieve with those devices, that would be a plus.

(Cross-posting this across several communities in hopes of getting some discussion.)

I'm currently building some indoor climate sensors for my home. My idea is to have temperature, humidity, noise, light, VOC and CO2 readings at a relatively high frequency reporting to my MQTT server.

I am currently setting up some different temperature sensors, and I want to calibrate them (hopefully just a linear offset) and evaluate them on some metrics, such as sensor-to-sensor consistency and accuracy.

To calibrate and evaluate the accuracy, I would need a source of truth, and ideally I would also be able to cycle it through a range of realistic values for the given metric.

What are your strategies to tackling these things? Do you assume the sensors are already well-calibrated and don't bother with this? Do you have a dedicated reader for any sensor value you would want to calibrate?
