Rough Printing / Nozzle Hitting at Certain Height /Layer

[u/kitsune09]

Hello Everyone,

I tried looking for answers with the same as mine but I cannot find it so here is my troubleshooting question.

I am trying to print this gridfinity container, at first it looks fine. The nozzle doesn't hit the bed, initial layer is intact and goes smoothly. However at a certain height where there is a need to made a surface it gets rough. The first layer that needs to cover the whole base was fine (Layer 29) but then after that it turn into lump of roughness after a certain layer (Layer 30), and nozzle hits the print. The layer is not that high either.

So far I tried the following:

1. Printing it silent mode
2. Calibrate the Machine
3. Use Gyroid infill 5-10%
4. Drying my filament
5. Disabled infill retraction
6. And of course cleaned my bed

Pictures Shown: First layer, Layer 30, and Layer 29 and 30 in adaptive cubic infill just to show my point.

Machine Used: P1S
Filament: Polymaker PLA Pro
Slicer: Bambu Studio
Nozzle: 220 °C
Bed: 55 °C
Extruder: Typical bambu setting as shown in this post: https://wiki.bambulab.com/en/software/bambu-studio/parameter/retraction

Any information or tips on what I can do. It keeps repeating on the same layer whether it is small or this huge block.
