Auto-leveling on AnyCubic Kobra 2 Plus

[subtle pond]

Hey everyone, new to 3D printing here and I’m checking in to see if this is the “norm”.

Just got my AnyCubic Kobra 2 Plus (Firmware version 3.1.2) and set up seem to have gone fairly smoothly. The initial set up that got prompted on the screen all went well.

During the auto-leveling, everything seems pretty good, nuzzle was touching the bed and the Shark Bottle Opener test print came out well (I don’t recall if I ever checked z-offset as it was printing).

Ain’t sure what I may have done but now the auto lever doesn’t even touch the bed like before. Not only that, at parts it isn’t even probing the bed (are off to the side).

Video below to see what I mean.

After auto-leveling, I had to set z-offset to -1.80 to get a decent print, as well. What did I do wrong? What is the fix for this?

Thanks in advance.

It sounds like there may be an issue with your auto-leveling sensor or the bed leveling process itself. Here are a few steps you can try to troubleshoot and potentially fix the issue:

1. Check the auto-leveling sensor: Make sure the sensor is clean and free from any obstructions. It's possible that the sensor is not detecting the bed properly, which is causing the issues you're experiencing.

2. Re-calibrate the auto-leveling: Try re-calibrating the auto-leveling process according to the manufacturer's instructions. Sometimes, the sensor needs to be re-calibrated to ensure accurate bed leveling.

3. Check the wiring: Inspect the wiring between the auto-leveling sensor and the control board to ensure there are no loose connections or damaged wires. If the wiring is damaged, it may need to be replaced.

4. Adjust the z-offset: If you had to set a z-offset of -1.80 to get a decent print, you may need to fine-tune this setting further. Experiment with adjusting the z-offset to find th...

I've:
▪️ Checked the auto-leveling sensor, it's clean and no obstructions. Double checked with a height gauge as well.
▪️ Recalibrated already and same thing.
▪️ Checked wires, all good to go.

might be the sensor shift a bit

[subtle pond]

What's a way to check that?

[viscid vale]

im not sure how anycubic printer were built but u can try to tap the sensor see if moves

[subtle pond]

Nope, doesn’t move.

[viscid vale]

what about nozzle

[subtle pond]

Doesn’t move either. Both pretty secure.

I have kobra 2 plus as well, i have my offset at -1.84

[viscid vale]

humm does it affect ur printing?

if not might go to the setting see if u can set the offset

[subtle pond]

I’ve been fiddling with that and -1.75 is still too high up so I moved it to -1.80, seem to be okay…I think. 🤔

[subtle pond]

Can only set offset during printing. So far it’s sitting at -1.80.

I’m extremely new at 3D printing so I don’t even know if what the video is doing is the norm.

Just wondering (since no one has responded to my thing), you run into anything similar? https://discord.com/channels/167661427862142976/1274932124381872161

I just know it was running auto level fine then I don’t know what I did and now that 😅 😭

[alpine bronze]

Mine does the same

(Also sorry if necroposting isnt allowed i literally cannot print anything new from the app)

[viscid vale]

i didnt saw any problem but yeah always need set offset is kinda annoying xD

[subtle pond]

Well the system seems to remember the previous numbers…I just don’t know why auto leveling is doing that…

[viscid vale]

also this thing is the sensor

[subtle pond]

Yes, I figured.
It’s right next to the nuzzle. Both snug and not wiggly or I can’t move it.

Anyone else got any ideas?

i'd say if it works it works (my print head is tilted by like 3 degrees)
