3D Printer Blobs: a mysterious problem you won't guess how to fix

excelent video! earned a new subscriber

i have a question? why not blug the printer into a UPS batttery?

so cool!

-It's round!!
-Precisely!
This had me guffaw !!
🙏👏👏👏👏🙏

And that's kids, why we use octoprint on raspberry pi. 4GB ram is more than 800 times 16KB.

Great video! This is the sort of thing nobody predicts that brings air traffic control to its knees, "lol"...

ok my guess is you were eating a ham sandwich within spitting distance of the machine BUT you still had on last nights high heels causing a spiral deformation of its internal demorgrafic rediency....but i could be wrong so lets watch the video and find out

I have this problem with my Neptune 3plus but with straight surface too. My old CR10V3 printed really well and was great at fine detail. Haven't been able to get the Neptune 3 anywhere close. Always looks really rough.

Ive heard of 3d printers. Thats how far into it I am lol. I didnt even realize people had these at home. I thought it was like only in a science lab or something by a government.

Good video and better explanation. Great job!

So people are spending thousands on 3D printers for what again? I don’t see any practical use for what it produces. Unless your goal is to be a toy maker it will not produce any actual parts. Plastic is soft and breaks easily no point in these printers.

I use Cura, so would adding G-Code
M413 S0
to the start code, be something that could work?

This seems like exactly what's happening with my prints lately ! I was wondering why the nozzle would stop randomly too ! The Netpune 3 does have a "resume printing" option, with a lightning cycle logo that perfectly fits for a power loss recovery logo. I'll try disabling it.

the Octoprint issue, i wonder if your longer cable was USB 1.1 cable? USB 2.0 LOOKS identical, but transmits data LOTS faster. typically, a cable's length doesn't affect speed, unless it is over 25 feet...

what about if you print directly from the computer? does it still blob?
like you mentioned, the simplest way would be a good UPS. a decent one runs between $100 - $150. i like APC ones :)
luckily, my 3DP is old enough it doesn't have such "advanced" features! lol

Yay! I said, "cache!" as soon as I saw the print. I didn't know it was related to the power loss recovery mode. Nicely done

Hi. Will the file download work if I’m using a sonic pad?

I had this issue on my Elegoo N3Pro from one print job to another, same file, same filament same everything.
Thanks to this video I changed out the cheap SD card which came with the printer for another sub-32 GB FAT32 SanDisk SD Card and voila - zero blobbing.
No power recovery control needed to be turned off to get back great print quality.

why my older printers dont do this bc they dont have power off recovery lol

Good points ! never have guessed

has anyone used this on a VOXELAB Aquila X2

Yyyyou're going to need a cream for that.😂

Thanks!

lol, your movements for this video are so fast compared to your words and it looks kind of goofy and gave me a laugh... the video was good too

Ok, so we have identified yet another cause of blobs and how to make them go away. But, what if a person wants blobs as a pattern or randomized for texture effects. I refer to blobs as a unrealized feature because although they are nuisance in most cases, there are times when adding a texture is desirable.

this should be pretty easy to fix, there should second static queue of command which would contains proper step so when the printing queue is empty filament can be stopped/retracted(or whatever else is needed). Than once new commands are read proper recovery can be made before commands are put to queue, it may be worth filing a bug report

heating issue? ( this was a guess!)

Quick question, totally new to 3d printing, my issues aside from some bubbles, I keep getting strings on my pieces.

I literally gave my first printer away because of this exact issue it drove me crazy for a year man if I had this video then thanks for solving the problem there were a few of us pulling out hair out over this a few years ago

Thanks

I find you can stop this happening by drying your filament, even PLA will benefit from drying for a few hours

Thank you so much. This fixed my issue. I was going insane. Thank you so much.

Bro i have been tuning everything else trying to fix this smh. Great video.

@GeekDetour - is this still an issue on the Neptune 4 and/or Klipper?

Thank you for figuring this out! I tried printing in vase mode a small Egg model for last Easter to use up my remaining pink filament. I never used vase mode before for anything, so I was surprised to see an outer spiral artifact on the printed model -- Now I know why!

I really like your presentation style and how you explained what was happening in depth so we could understand just how the problem occurs. Hope to see more great tips, tricks, etc.

I immediately subscribed 🙂!

So use a USB stick?

Maybe the printer is bad?

Marlin? any one use marlin next Klipper Coming out? Deprecated marlin and very dangerous!

why does he move in 2x speed?

Can it be deactivated in creality ender, for example V2?

The funny thing is that I already guessed the answer when you mentioned "power failure recovery", because this is basically a reenactment of the problem that old pixel games used to have back in the old days, when pixel games used to squish the cache with encapsulated blocks of color information, and when they ran out of RAM there were all sorts of bugs and all sorts of strange color blocks appeared on the screen. When the memory ran low, all kinds of bugs would appear, and all kinds of strange color blocks would appear on the screen.
It's interesting to see how this phenomenon has been repeated in the 3D era.

Just perfect

Now this is what I'd call a 3D printing education video!

or just turn on circle commands in your marlin and slicer settings, making each layer one line

I have the problem when using superslicer on a artillery x1 SW, I also use SD cards, the problem is constant, have it on any object (round or rectangular) and in diference to the video the blobs are very small, i have no idea how to fix it. its not wet filament and no seam configuration. got to mention, i have other 2 printers with same filament and same slicer and no issues, only on the artillery.

DONT BUY BAMBU LAB, Got 1 , 1 month ago, still not show up, you can try to call customer service, goodluck ever getting answers, trash company, all these review purposely dont mention its horrible customer services and bait our money in
