Just a quick update that I’ve been printing much non-stop since I posted the message about unplugging the camera. Haven’t had a single nozzle crash since. I working up the nerve to plug it back in and start diagnosing because I really miss the camera, but not at the expense of it trying to destroy itself…
Ryan,
I had the same, installed a camera on the K2SE then repeated crashes, I’ll try your suggestion of unplugging it and try again.

Hi,
I’ve been following this thread for a bit as it seems that this crashing issue is big problem for a lot of us. I just wanted to check in to see if with the camera still unplugged if it is still working? I am looking to do this step as well but have to wait for an extruder gear first to arrive (the metal teeth that hold the bowden tube broke apart inside) My son and I have been trying to get the printer to work for a long while and this is the first thread I have found that actually sounds like its getting anywhere.
Thanks.
I have been printing non-stop since I unplugged and not once had anything even remotely close to the nozzle hitting the plate. I have literally been through 4 or 5 spools of filament and have yet for it to even remotely hiccup (with the camera unplugged). I have NOT tried hooking it back up yet. There has been an update to Print and profile updates in the past few days - I am unsure if that would control this or if it is more of a firmware thing. I’m still catching up on the things I needed printed, but I do miss the camera (particularly when printing ABS or something way more finicky than PLA) so I will eventually try it again - I was hoping to get some official word from Creality via a response or firmware change log, etc…
Regardless, I can pretty much guarantee at this point that unplugging the camera will fix the issue.

No problem after unplugging the camera

Firmware issue indeed. I recently installed a Nebula camera and happily switched on the AI functions. First thing that happened when sending a print job, I got a nice deep scratch over the build plate. Figured it had to do with the camera, so turmed the AI functions off and the K2 SE was printing again as it should. Turned AI on again with instant crash as result.

Ok, so based on that feedback and the fact that I just got notice of a firmware update which went smoothly, I think I’ll try the camera without AI over next couple of days and report back. If that works reliably, then I’ll see about troubleshooting what turning on AI is doing to make it go crazy. Since it isn’t EVERY time, there must be some pattern to it, but since it is “AI”, the results could actually be unpredictable over time. I want to see if I can see the commands being sent though in Fluidd and find at least why the command is malformed to make it Z crash.
If you’ve had the problem, couple of things to be aware of:
- Apparently (based on various posts I’ve seen) the plate is reversible? No, there is no brush nozzle cleaner, but a lot of the replacement plates don’t come with that either, so I don’t think it is a huge deal. So, IOW, don’t throw the damaged plate away (plus mine has about 60% good printing on the damaged side too…
- The last crash I had actually made the Z belt slip on the front right side (where the nozzle crashes), resulting in a diagonal slant of almost 6 mm back left to front right and this was more than the calibration compensation could accommodate. It meant anything large was shorter on the front right corner by over 1 mm (and actually got worse the taller the object was). I didn’t realize it happened, so be on the lookout. You can use Fluidd to generate a heatmap of the bed leveling and you can paste the text results into AI to interpret how good/bad your bed leveling is…
Hope this helps someone!

So I just wanted to thank you guys for the info in general. Unplugged the camera and still have not had a crash since. Cant seem to figure out the correlation yet. But nonetheless I am up printing. Thanks!
I am glad that this issue was somewhat resolved. I am concerned that my crashes seem to be due the main board which was replaced but I also never had my camera set to AI detection. This still leaves some question to what really caused it. Hopefully Creality reads these forums but i think that is unlikely.
Gracias a Todos… este problema es claro no es solo a mi… un alivio por ese lado.. tengo exactamente el mismo problema reseteo a modo fabrica y realice todos los pasos, y se mantiene el problema, desconectaré la cámara para probar, pero ya tengo 2 placas con una linda cicatriz, ¿como se puede solucionar el tema de que este mas alto o bajo una de las esquinas son como 4 mm de diferencias medidos con un pie de rey (como le dicen en LATAM). prove con el ultimo firmware que me baja la impresora .66 y nada, restaure a la .49 y nada… ahora probare con lo de la cámara.
Muchas gracias
Realice una prueba de desactivar solamente la IA, dejando la cámara conectada… y volvi a sacar el mismo que modelo que trae de stock y ahora funciono sin problema.
Por ende creo que tienen razón los colegas, el problema es la IA… estoy usando el ultimo firmware que me descarga la version 2.3.6.66 y la del CFS 1.4.2
Modelo Creality K2 SE
