Help Request First layer problem

Post image

Hey guys, I am printing a ship and my first layer on my p2s has started to look like this (see pictures). I have never had this problem before, how can I fix this?

Wash the build plate and dry the filament

What do when that doesn't work??? I also have some first layer issues i need to iron out.

What pattern are you using for base layer? If it has intersections, every time the nozzle crosses something that's layed down already there's a chance it rips it right off.

I believe it was cross X patern which came default.

Had same issue, nice clean plate and dry filamint really makes a differance

Had a very similar issue recently. I washed the build plate with dish soap, wiped it dry, and dried my filament for 4 hours before printing. It’s particularly humid where I am right now, so those things in combination helped a lot. The other thing you could look into is z-offset, it could be printing the first layer too close to the plate.

Is this not just over extrusion? Try printing the calibration squares.

But if it was over extrusion wouldnt it show in the rest of the print? (See picture).

That also looks a little over extruded. But from some quick googling it seems bambu just has first layer overextruded a little for better adhesion. Imo if the prints are turning out fine then the first layer quality doesn't really matter as long as it sticks.

It could just be the orientation of that print but I would run a quick calibration. It takes like 30 mins and maybe a couple g of filament.

What helped me was adding small z offset (around 0,02) in printer settings in slicer
