  • Most likely something on that channel is spamming multicast. That kills most consumer wifi routers (in default settings). Usually something like a sonos or Google home broadcast group.

    I might (i.e. I definitely do) have a non-ideal setup at home that contributes to this, with the router/WPA, a RPi running HA with a Zigbee antenna just next to it, my server in the shelf next over and a Sonos above it. Worst of all, the server is running on WiFi and it is sat in immediate vicinity to my router. Why? Because I could not for the life of me make the ethernet transfer speeds be more than somewhere around 1-5 MiB/s, so I gave up. But considering these issues are so infrequent from this location I assume it is mostly due to outside interference.

    And adding to that, …

    Use an app like PingTools (Android) that can graph what is on each wifi channel. Check to find the cleanest channels in your area and configure your router to use that channel.

    … this scan shows that all discovered networks are occupying the same channels (98-114 it looks like). I have still not figured out what OpenWRT option to go for (the OpenWRT One, which I had originally planned, quickly became very expensive with imports and tolls that I ended up not buying, despite having decided to go for it). So I am using the stock ISP router, which I assume everyone else in my building are as well. And I have been unable to locate an option to change channels in its interface.

    If you’re curious and technically-minded, I highly recommend this write up: https://www.wiisfi.com/

    That is a resource I didn’t know I needed! Thanks :)



  • I use this:

    rsync -rah --progress /path/on/source/ user@ip.of.local.server:/path/on/destination
    

    I will try the ping next time I attempt this. There doesn’t seem to be a definite time when the issues start though. It tries to copy the file over, and when it is done it continues to the next. If the first one didn’t succeed, it will retry and if that also fails, it will say “ERROR verification failed - discarding update” (paraphrased) and continue to retry the next file if that also failed.

    I do see some fluctuations in the transfer speeds during transfer, which could indicate the times the connection is struggling.









  • ETA: Well, I toured the Calibre-Web settings again, and now I can upload books and covers. Must have been a little tired on my first attempt. Still couldn’t get the conversion to work properly - I only have the option of going from EPUB -> KEPUB (whatever that is). I typically prefer reading PDF on my current reader, and I have users who need .azw3 for their jailbroken Kindle device. I guess the paths to the conversion tools aren’t properly configured.

    ETA2: Now I got the conversion to work as well. Seems like I will be able to use it with Calibre-Web only as well. Nice!

    Hm, I’m using lscr.io/linuxserver/calibre-web:latest, which is version 0.6.26 (5a1f3d8eec42d03228b1e5dec9bc750ca10bbc94 - 2026-02-06T20:40:07+01:00). Looked again to see if I could find a way to do it, but no.

    How do you upload books directly using Calibre-Web? And do you not have Calibre running behind at all, just the original database?

    An other shortcoming of Calibre-Web seems to be that I am unable to convert books from the UI (that is thankfully very easy to do in Calibre). I added some Docker mods that I thought would allow me to do this, but I have at least not found a way.

    Nice to know it works with Kobo - I don’t have one, but if my current reader stops working I am likely to get one of those.



  • It is important. But I find the ones I have tried good, and would survive if I had to use either of them. I use KDE Plasma on my main personal laptop, I have Cinnamon running on a living room computer connected to my TV (not an ideal solution, but I’ve so far not taken the time to optimize the setup) and GNOME om my work laptop. I much prefer KDE Plasma out of them, but I like the others also.








  • otherwise they will be prone to warp and collapse in on each other. If your item will be as tall as you suggest, this is likely to happen before the print even finishes

    Yeah, this is what happened in the original, failed print.

    I ended up making the model with 3mm thick walls, using two perimeters and 10% adaptive cubic infill (I sliced with gyroid as well, but it looked weird). Turned out great. I made some that were not quite as tall as well, with 2mm thick walls and 3 perimeters, which worked fine as well. It might have worked for the main boss here as well, but I’m not quite sure. The difference between the models was about 55 mm in height. The difference in material usage between the two options was negligible (< 10 g), with the infill variant coming out slightly lower in consumption.


  • Good lord no. Don’t do that. That would be a waste of filament and also cause a host of other problems for you.

    Just to be clear, it is the “hoping to use infill to get some support” that your response is aimed at, right? Out of curiosity, what kind of problems could I be looking at for this?

    In the meantime, I’ve been printing some smaller bins of about half the height of my problem where I increased the wall thickness of the model from the default 0.95 mm to 2 mm, and used 3 perimeters, which resulted in fairly sturdy walls.

    Looking at the same bin with 2 mm walls without infill, and 3 mm walls with infill, there is barely any difference in material usage.
