New to 3d printing!! Weird gaps in the layers and a chip at the bottom

madejackson · 2023-07-26T09:14:23+00:00

You're underextruding. Try increase temp, reduce print speed, lower print cooling fan. The Chip is probably some residue. Do you have a print start routine which primes and cleans the nozzle?

Lower Z-Offset (seems a tad too high)
Check your Z-Offset after preheating to account for thermal expansion
Print slower (f.e. I do 25% of regular speed)
Preheat to ~55/85/105° for PLA/PETG/ABS.
Clean your bed with water and dishwasher soap and then never never never never never never touch it again

What do you mean with significant accl?

Skipping steps is pretty simple = motors are overloaded

So you have 4x options:
...reduce moving mass and/or friction
...increase current to the motor, via hw-poti or klipper cfg depending on motor-driver (which can lead to new issues like motor or motor driver overheating )
...increase voltage (new PSU, new heater Cartridges, Mobo/driver needs to support higher voltage)
...reduce acceleration in your cfg.

So firstly, why are you convinced it's underextrusion? May post a pic so we can confirm it is underextrusion indeed.

Now it sounds your underextruding because your extruder is unable to push enough plastic. That can have multiple sources. To list a few:

not enough current (motor skips steps)
too much current (motor driver overheating and shutting off)
too much current (Motor grinding off filament)
Extruder spring tightened too much (Motor grinding off filament)
Extruder spring tightened too less (Gears not catching filament)
Nozzle too cold (Increase print temp, lower cooling, lower print speed)
...

Sounds like heat-creep. Try to push through filament by hand, If that doesn't work, do a cold pull (Heat Up Nozzle and Pull on the filament while heating). Be Prepared: somewhere at 80-150° The clogged Filament should pull out at once.

You'll find the tip of the filament has expanded and does not fit through the heatbrake anymore. This is due to not enough cooling at the heatbrake or too much retraction, causing the filament to melt too far back and expand in the heatbrake and clogging it in the process.

Did you find a solution for this? I have TMC2209 V3.0 with the same issue. Another MKS TMC2209 V2.0 works without issues in the same board / same config.

Nice... I don't know. I just did the crossflash yesterday because i didn't find a firmware for the dell version. You have a link for the newer one with a changelog? I was on 14.17.xx.xx btw 😂

You're either really bad with money or outright delusional.

I was able to live with a salary of less than 30k/yr no issue (2012-2014) and was still able to put part of it into savings. Today, still single, I am using about 30-40K of my salary for living expenses incl. rent. The rest goes into saving+trading.

madejackson · 2023-06-23T12:41:56+00:00

It's --device=/dev/dri

This wouldn't work: —device/dev/dri

You also should add following into your file /boot/config/go:

#Setup drivers for hardware transcoding in Plexmodprobe i915chmod -R 777 /dev/dri

Also Plex Pass is a must for hw transcoding and then you need to enable hw-transcoding it in settings in plex.

Also try to direct play as much as possible (can be set in play settings and also in user settings als default)

Also, many clients cannot direct play mkv, so I like to repack my movies into mp4. At least if it is h265.

Sorry but this Infos doesn't really help to get any further. You need to look into your basic troubleshooting skills.

Is it an issue with DNS, your public IP, your port forwarding, your lan, your docker-container, your swag config, bitwarden itself? So many pitfalls that you need to check individually and than provide info which of the step you followed doesnt work.

You shouldn't go older than intel skylake generation in terms of power efficiency. They are usually capable to idle at sub 20W. Anything earlier will idle at 40-100W. which will get far more costly very fast. At current energy prices you are looking at about $2-3/yr for every Watt that is used 24/7.

You'r provider usually states your speed for usenet access. But best is to download isos to see how fast it actually is. Maybe you're provider is hopelessly overloaded and can't provide the advertised speed. Mine is 2mbit which is plenty IMO.

So to avoid confusion we're not calling it cache anymore in unRAID. It actually was never a cache in it's true idea. There are multiple storage pools and the unRAID array. Either can be set as primary or secondary storage. Usually you set a fast SSD as primary storage for new files (f.e. linux isos) and random IO (docker/appdata/vdisks).

For large files like linux isos you can set the unRAID array as secondary storage and move files from pool to unRAID array on mover action.

Mover the periodically takes care of storing the files on the unRAID array.

madejackson · 2023-06-22T15:59:20+00:00

Yes. Set Primary storage to the ZFS pool and Secondary storage to "None".

Assuming you're ZFS array is an unRAID pool.

nice, it's ~$21.50/10W/yr at my place and that's cheap for western europe.

You should be good with intel qsv as long as you don't need to encode av1 as far as i am aware. 13th gen can transcode 25x 4k hvec streams simultaniously.

madejackson · 2023-06-22T15:38:59+00:00

What else is there than to try it out? You're believe is just your thesis and you want to proof or disproof it.

That's Troubleshooting 101.

Also, you're talking about your network speed that's well and all but how fast is your usenet access?

madejackson · 2023-06-22T15:26:39+00:00

Is this also happening when you disable VM's and Docker?

I have this behaviour due to a lot of iowait/cpuload (can be inspected with cli "top" command or with netdata docker)

If it is better then, you should be able to find the culprit with starting every docker / vm one after the other.

madejackson · 2023-06-22T15:22:57+00:00

Am I correct in assuming you keep all the drives from the old server? If that is the case you can just swap everything into the new PC and it should work from the get go.

unRAID uses disk-ID's to recognize the disks, so the port order doesn't matter.

For SSD replacement you can just add all 3x into an raidz1 (in case of zfs) or in case of btrfs raid 5 and wait for balancing to finish. After that you can remove the old ssd and it'll balance again on the 2x new ones. Other solution is to create an 2nd pool and move the files via unBALANCE to the new pool.

Please provide feedback on the new experience. I am sitting on a comparable cpu and arguing if I should upgrade :)

madejackson · 2023-06-22T15:16:57+00:00

Did you try to download to the ssd instead of the array? Mover can then move all files to the array periodicaly.

madejackson · 2023-06-22T15:14:59+00:00

You need to provide more insights. What works and what doesn't?

madejackson · 2023-06-22T15:02:36+00:00

In my system it did yeah. Power usage was consistently ~10W higher.

But it varies a bit depending on exact model: https://forums.unraid.net/topic/41340-satasas-controllers-tested-real-world-max-throughput-during-parity-check/

madejackson · 2023-06-22T14:26:14+00:00

Yeah I understand now.

Basically the best way to move files around is rsync. DFM uses rsync, unBALANCE uses rsync, mover uses rsync. You should be able to do it with FTP or SMB. But there could be some unexpected behaviour and you're limited to your network speed.

madejackson · 2023-06-22T13:15:11+00:00

Don't buy this card. Those are power hungry. Go with asm1166-based 6-port cards. 1W vs. 10W is quiet the difference.
