Hehe you are awesome 😂
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

cache few years, but time to time I have problems w

Thx, Ill check it out
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thank you a lot for being patient with me :D
```
dd if=/dev/zero of=1g-testfile bs=1G count=1
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.62269 s, 232 MB/s
```
This HDD is obviously working fine and much faster than I thought it can. I guess I have to find bottleneck elswhere
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thank you. The files I download are usually 5-30 GB size. I don’t want to max out my internet speed, I just want to get the files in media library ASAP after requesting download manually (happens maybe few times a week)

It makes sense, Ill test sequential and random write performance and maybe even test it since I have the hardware available.

At first I wasn’t aware that my speed is super low for HDD, therefore I was looking for some magic solution with SSD speeds and HDD storage that might not even exist. I have to do more testing for sure
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thx. Ive seen dd commands in guides how to test drive speed, but I’m not sure how can I specify what drive I want to test. I see I could change “if” and “of”, but don’t trust myself enough to use my own modified commands before understanding them better. Will read more about that. Honestly I’m surprised drive speed test is not easier, but its probably just me still being noob xD
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Ill look into ZFS, but in meantime I found out my HDD is probably not bottleneck. Still want to learn about this so thanks for your comment
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
I have managed to copy with rsync and getting 180 MB/s. I guess my initial assumption was wrong, HDD is obviously not bottleneck here, it can get close to ISP speed. Thank you for pointing this out, Ill do more testing these days. Im kinda shocked because I never knew HDD can be that fast. Gonna reread all the comments as well
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Yeah feels like that lol. Thx anyway, have a nice day dude
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Yeah it will be faster, but its extra step before the files get available on HDD.

Even if my HDD is super fast and healthy it would still be a bottleneck for 2Gbps fiber? Ill deffo play with HDD more to find max speeds, wasnt paying attention before because it felt normal to me
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Well yes, but I was hoping files can be available (imported to media server) before they are moved to HDD. Import is not possible from incomplete directory if I understood that correctly (*arr stack)
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Oh, you are talking about torrent client settings? I could spare 1-2 GB of RAM, but not more than that (got 16 GB in total). I see this might help a lot, but I would I still be limited with HDD max write speed? Using SSD for temporary files sounds great, but waiting files to be coppied to HDD would slow it down if I understood correctly
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thanks, Ill check mergefs
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Ive heard about all of these before, gonna do more research. Thank you
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
I might try that, thx
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Yeah, but need to figure out how to see transfer speed using ssh. Sorry noob here :)
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Its the cheapest drive I could find (refurbished seagate from amazon), I thought thats the reason for being slow, but wasnt aware its that low. Im also getting 25-40 MB/s (200-320 Mbps) when copying files from this drive over network. Streaming works great so its not too slow at all. Is there better way of debugging this? What speeds can I expect from good drive or best drive?

Ill research more about BTRFS and ZFS, thx
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thx. I use ext4 right now. I might consider reformating, but so many new words to reasearch before deciding that. I heard about ZFS, but not sure is that right for me since I only have 16 GB of RAM.

Downloads are 100-200 GB max, but less than 40 GB most of the time. I have 512 GB in use and 2TB SSD not in use, can swap them if needed
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Are you also talking about incomplete directory in qbit? Doesnt make it faster afaik, but I might be wrong. I havent tried anything yet, wanted to check is it something usual or not worth at all. Got zero experience with using SSD as catch drive, it just made sense to me
⁨Comment⁩ on ⁨Data HDD with SSD catch drive⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
But that would first download to SSD, then move to HDD and then become available (arr import) on jellyfin server, making it slower than not using SSD. Am I missing something?

⁨Comment⁩ on ⁨PLA warping during print⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
This is correct, shrinking forces are fighting against bed ashesion. I use 60C and then drop it to 55 tho. On top of that you need clean bed and revisit first layer squish
⁨Comment⁩ on ⁨Why is Google takeout so bitchy?⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:
Im surprised that feature exist tbh. It worked fine for my 20GB splited into 2GB archives if I remember correctly
⁨Comment⁩ on ⁨Do you poweroff your server during night / unused times?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
24/7 and no UPS. Drains 33W on idle which I found good enough for me
⁨Comment⁩ on ⁨Auto bed leveling on Ender 3 Max Neo⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
I see the mesh, but cant tell what is wrong with it. Is your mesh about the same every time after running ABL? If you check any point on the right side, do you think your bed and nozzle are at the same distance after every ABL run, but sensor reading is wrong on that side?

Basically you have to identify is your sensor faulty, otherwise your bed or X gantry might be moving in Z over time. Faulty sensor can be fixed or replaced or just go to manual mesh leveling.

I would try probing the same point multiple times in a row and see what difference you see in readings. You could also do a manual mesh and compare it with auto bed mesh.

Move nozzle close to the bed, disable XY motors and move nozzle around while observing the gap. 0.1 mm variation can be seen by naked eye (alternative to paper method) and you have 0.6 mm according to your mesh.

Use a metal ruler (or something flat) and a light to confirm how much and where is bed bent, again visual inspection.
⁨Comment⁩ on ⁨Auto bed leveling on Ender 3 Max Neo⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
You get different map every time? Maybe your sensor is not trigering consistently? Is it wobbly? Hopefully its the sensor issue, otherwise its probably hardware issue (X Gantry or bed).

the right side of the bed is always printing too close

If the height diffetrence is always the same, you can try manual bed mesh leveling (sensor not even required). Create one map and load it every time. You can also just eddit existing map if you know what is wrong.
⁨Comment⁩ on ⁨Automatic Fire Extinguisher for 3D Printer Cabinet⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
I agree with you mostly, but there are also unfortunate examples with big eu brand as well. Im not paranoid, but home 3D printer is more like production machine than kitchen appliance imo. They have moving parts and print failures happen sooner or later. Fire in a kitch

Before reading comments, I wasnt aware that prusa is selling fire suppression system, but I guess there is a reason for that
⁨Comment⁩ on ⁨Automatic Fire Extinguisher for 3D Printer Cabinet⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
Thx for sharing. Usefull information
⁨Comment⁩ on ⁨Automatic Fire Extinguisher for 3D Printer Cabinet⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
This one would be more difiicult to mount in my cabinet, but the main reason Im eying can type is that I found multiple recommendations and also that thing cant be activated without flame afaik.

Im glad that people in this community dont have much experience with these, but that makes it more difficult to find the best product
⁨Comment⁩ on ⁨Automatic Fire Extinguisher for 3D Printer Cabinet⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:
My printer is behind shelly plug as well and I was thinking I could mount temperature sensor and smoke detector that shuts down printer through homeassistant and alarming me if needed. Testing and trusting that automation might be difficult tho. I do have camera as well, but that thing wouldnt help if shit happens while im in the deep sleep. Extinguisher would live on top of that.
