H2D left nozzle wiggle and bed leveling inconsistencies

Bambu Lab H2 Series
1

Hi everyone,
I have been having minor bed leveling and first layer issues for a while now but still have been unsuccessful in fully diagnosing it. It is also not very pressing because the effect is only minor, but the nozzle is always too low on the first layer.
Today I noticed that the left extruder can be pushed up. It is not loose per se, but I could imagine this amount of movement messing with the bed leveling. Could you please check your own printers and tell me if the left extruder is supposed to do this, or if there is something wrong with mine?

Thanks a lot for your help!

Mine does the same. However left and right nozzles don’t seem to behave differently in regards to the first layer.

However, even with the right nozzle my H2D can’t print a clean first layer.

Same here. The left nozzle behaves the same.

Also my first layer on both nozzles is fine here.

I do notice that bed levelling requires a bit more retries. But no further issue though.
Tightening the screws on the left nozzle did have some effect, but still not as dead on as on the right.

Did you find a solution to your problem?

I have the same movement on the nozzle, but i have problems with the nozzle either being too high up on first layer, or too low on one of the layers afterwards ending up with Spaghetti or the beginning of a blob of doom.

There’s been a lot of firmware updates pushed (some as recently as a week ago).

If you have updated, disregard what the screen tells you about partially calibrating (just doing noise or motors etc.)

Take the time and do the entire gamet and check marking off every calibration tab there is to do and retry your 1st layer. I’m betting it will make a world of difference.
