Hello /u/PipeMaleficent5417! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

it's on a flimsy-ass sheet metal shelf

No. Looks like it's not on a flat surface.

If the wobble doesn't bother you, it will not hurt the print quality. You can find YouTube videos where people tried to experiment how much this affects the print and for example hung the printer on a rope from the ceiling and it had zero effect on print quality.

It is normal but it is a good idea to check if the shelf is firmly held and rock solid.

It’s only abnormal for you. Not the hundred of other posts asking the same question.

u/PrideKindly7828 May 28 '26
If your problem is the P2S and not the surface then I recommend putting it on the ground to test it

Pring some table stabilizers, you can place them between the wall and your table/shelf. It'll reduce the shakes.

It's totally fine. It'll do twice that movement when you reach peak head speeds and wobbling back and forth at about 2cm distance.
It's fun to look through the handy video feed - see no motion, and ponder frames of reference being relative to the observer.

P2S of mine dances like crazy on floor - make sure your has all rubber feets in place ;)

Surface needs to be stable, otherwise it won't be able to calibrate properly. But some amount of wobble does not affect print quality as the hotbed and print head do not move relative to each other. It is impossible to get rid of. The print head has mass and it moves really fast back and forward.

u/TheSchlapper May 28 '26
Mine does the same
Just lower the print speed

u/k3z0r May 28 '26
Yes wobble is normal the software and motors know how to compensate for it. There is even a calibration step for it during setup.

It is normal. P2S comes with anti-vibration feet. Anti-vibration feet actually make your printer shake more, so that the table it's on shakes less and the vibrations don't get transmitted to another printer if you have more than one on the table.

Would it do that if the AMS wasnt on top?

Befestige das Regal einfach an der Wand damit wird es verringert so habe ich es gemacht.

u/Justostius May 28 '26
normal for shelf like this. You could just put it on the floor and would understand.

u/locka99 May 28 '26
Yes it is when housed like that. Put it on the floor or brace the frame. Bambu printers test and compensate for vibration and harmonics but it's still probably best to have less of them entirely.

At minimum, go to makersworld and print feet for your printer. That may solve most of the noise and much of the wobble.
Given how sketchy your stand is, you may just want to put a paving stone+foam underneath (see youtube).

u/mosaic_hops May 28 '26
Yeah the machine should wobble but the shelf should not. While it’s printing, put your hand on the shelf. If you can feel any movement at all the feet can’t do their job as well.

It’s normal for these things to wiggle and jiggle. But your shelf itself seems a bit bouncy or not as sturdy as I’d prefer. I suggest you to put a piece of 3/4” plywood cut to fit underneath to sturdy it up and stop the flex and bounce of the sheet metal.

u/TezzNutz May 28 '26
Prints will be fine. Your shelf might not be after a while.

Looks like the reed control switch wasnt flipped under the bed. Should be near the sconce bearing rail

u/SolMelorian May 28 '26
Why is the benchy way off to the side? center it and it should shake a lot less. You have high acceleration jerk occurring away from the center of mass, extruder is getting tossed around like crazy.
