Whenever I print a flat surface the first layer goes down smooth, then any layer after becomes more and more bumpy as it goes up. After a bit of infill it returns to perfectly flat no matter how many layers get stacked? I'm incredibly confused. PLA+ 225°C Nozzle 55°C Bed.

I think your bed and the starting nozzle height are too close, so the first layer is bulged up higher than it should be. You don't see it because it's uniform, but it causes problems for the next layer because it doesn't have enough space.

Hello u/BooMiXx,

As a reminder, most common print quality issues can be found in the Simplify3D picture guide.

Please remember to include the following details to help troubleshoot your problem.

• Printer
• Filament Material and Brand
• Nozzle and Bed Temperature
• Print Speed
• Nozzle Retraction Settings

bed is level and nozzle is as high as I can get it to still print the first layer without it occasionally not sticking and missing parts
