Is there an existing issue for this feature request?

I have searched the existing issues

I have a Bambu Lab P2S that doesn't work well with adaptive pressure advance. No matter what I have tried, bridges and overhangs do not play well with it for whatever reason.

My first layer accel/speed is so low that a really high PA value works best (0.08+) but normal printing works best (0.03). When I try to find a middle ground that keeps solid/sparse infill extruded properly, the first layer is always far off or vise versa.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

A simple first layer PA value input and then a normal PA value input. Or maybe even have 3 values (first layer, outer wall, everything else).

Describe alternatives you've considered
