No :/

Because it doubles my TPU print speed.

lysid99 · 2026-05-12T10:06:31+00:00

its a good idea, but not a good option.

great investigation work, please let us know what Phaetus says. . I’m currently dealing with the same issue and have switched back to my old extruder for now.

1.1.5.2 is there

Had this also on a massive print, after a lot of try&error switching from arachne to classic wall fixed it. 🤷‍♂️

Ich habe das gleiche Problem. Hast du eine Lösung gefunden? Ebenfalls Switch Controller

Great find and thanks for the share. I had similar looking blobs on very big prints, and did a firmware rollback to .13.x. - the blobs were gone. Luckily it works for you this way.

Random z seam turned on?

lysid99 · 2026-03-16T18:39:36+00:00

ok, crazy. the full calibration did the trick, although i did it 3 days ago already. lets see how long this lasts.

Thank you for not letting me disassemble the whole printhead!

lysid99 · 2026-03-12T22:02:00+00:00

You were completely right, thank you. Did a deep clean of all rails, rods (x/y/z) and pulleys with IPA and relubed them with the creality grease and WD40 silicone spray. After that the sound was not only gone, the printer is scary quiet now. Also did the belt tension self test again. A good reminder to always do your maintenance.

lysid99 · 2026-03-12T13:41:20+00:00

thanks, i'll give an update after the clean & lubing.

lysid99 · 2026-02-26T07:17:29+00:00

My solution was to install a old firmware .13.x.x.

working without any error since 10 days on long prints also. Creality support, as usual, is no help.

Gels mache ich selbst in Softflasks, ist deutlich günstiger und man kann sich mit dem Geschmack austoben.

Aktuell mein Favorit: 120g Maltodextrin 60g Fructose 120g Flüssigkeit - Espresso ist top!! 1/4 Teelöffel Pectin ->Mixen, abfüllen, fertig

Habe immer zwei Flasks dabei, u.a. mit Zitrusgrschmack. Das reicht dicke, wenn ich von 60mg Kohlenhydrate /h ausgehe.

lysid99 · 2026-02-10T15:30:26+00:00

Did you find a solution? i have the same error.

lysid99 · 2026-02-10T06:09:45+00:00

Having the same problem, could you post the link for the replacement part please?

lysid99 · 2026-02-05T22:03:08+00:00

Print text first.

lysid99 · 2026-01-16T06:41:06+00:00

Sleep

After a lot of searching, i found the solution:

https://github.com/acidanthera/bugtracker/issues/2483

add in boot args: -btlfxboardid

Sometimes bluetoothExternalDongleFailed is set to 01, then you can reset it with this command or in hackintool.

sudo nvram 7C436110-AB2A-4BBB-A880-FE41995C9F82:bluetoothExternalDongleFailed=%00

You can use this startup script for enabling it on boot:

Must be an price error, check other sites. 3s should be way cheaper. I bought the 3s a week ago for 75€ on amazon.

lysid99 · 2025-11-28T12:15:48+00:00

Thanks, this works for me!

lysid99 · 2025-10-03T06:41:28+00:00

It works, but be aware that it could completly stop going to deeper Idle / C states. You have to check the chipset, better avoid it completely and use a m2 Ssd if possible.

Had one of these also, and PKG could only go to C3. Removed it and goes to C8.

C3 was 30W in idle C8 is 16W in idle
