Archimedean Chords Top Surface pattern Line Inconsistent

Bambu Lab A1 Series Troubleshooting
1

Hi, can someone help me? I’m using the Archimedean Chords Top Surface pattern (I need it for its design), but this is the output I always get — the curved lines are inconsistent in Bambu Studio. I’m using a 0.4mm nozzle on the A1 with eSun PLA+. I’ve attached a screenshot and my .3mf file.

Edit: I observed that it prints the center first, followed by the outer layer, and then returns to the center.

File contains no geometry and pic isn’t super clear

Is that whole “flower” supposed to be a single top surface on one layer, or is it curved? If its all one layer, you may need to tune your flow RATE. The geometry forces it to retract and move to the “petals” during the spiral, so if you’re flowing too much and shoveling excess around, when it retracts and starts a new path its gonna look non uniform
