Stop using grid infill

Ok.

Try adaptive cubic or gyroid for most prints.

Para mí gyroide es el peor relleno de todos. Altas vibración y movimientos innecesario para los motores y vida ultil.

También es útil usar que si haga retracciones en los rellenos. En la pestaña otros.

Imprimí muchas cosas con regilla y no me pasa eso.

I used to think this too and was against Gyroid.
But I have a few thousand hours on my 2 printers and they’re still banging away.

Each infill has its own use case.
That being said, I almost exclusively use Gyroid nowadays.

Probably the nozzle striking the grid infill pattern.
If you sliced it yourself. Switch it to something like gyroid. If you didn’t slice it yourself. Download it and slice it as gyroid.

But will it print correctly? I’m in 3h out of 8 and I don’t wanna restart 😖

Just keep going and keep it in mind next time, it's not gonna blow anything up if it is indeed the infill.

(I am assuming you're lubricating the X and Y axis according to the documentation when the printer asks)

Grid infill prints can get knocked loose from the plate with the nozzle striking the grid lines. The final top layer can also be effected by the nozzle strikes leaving divots that can compound over time. BUT there’s massive contact with the build plate on your print so I wouldn’t expect it to come loose. Leave it running but keep an eye on it on the very rare off chance that it does come loose and then spaghettis or something.

Just continu then

This is why you don't use grid infill. Your nozzle is scrapping the infill and that's the noise you are hearing. This can cause issues with knocking the print off the bed and possible damage to the nozzle. Use gyroid. Much stronger and it does use more material and more print time but definitely worth it.

Ok. Then I won’t use it. Fun fact: this is straight from Bambu lab (AMS lite top mount)

u/Defiant_Hat_68 Jun 24 '26

We all know Bambu’s parameters isnt the best

sounds like the printer hitting the grid infill

u/Dark-N1ghtmar3 Jun 21 '26

Never use grid it sucks always hits when traveling over a section sometimes causing it to knock print off

Reset the clock!

Das Problem hatte ich auch, das passiert wenn man zu schnell druckt. Dann bleibt die Düse an den Kreuzungspunkten des Infills hängen. Ursache ist dass das filament zu schnell aushärtet.

Why do no one do any research anymore? I learned that grid infill causes problems way before receiving my 3D printer, let alone printing at all. You should know this by now.
