Printing PC Filament from Bambu with X1C

Bambu Filament and Accesories Filament
1

at the last Bambu filament order is the PC filament (without additives) noticed. according to the specifications in the data sheet, the material is very interesting for technical components.
after unpacking it was dried according to instructions (ok my dryer makes only 70 degrees, but dried for 20 hours). In the X1C inserted it is immediately recognized, there is also the filament to select, fits so far.

The first parts are printed in standard settings, then the speed and acceleration was drastically reduced test, but the result was significantly worse.

What could be the problem?

Thank you
Best regards
Daniel

better use orca slicer and use the full range of calibrations…dont trust too much in the bambu profiles

I use the orca slicer, but I don’t make the calibrations yet

now I make all calibrations with orca slicer. bit the result is not that much better. the corners are too fat.

any ideas?
reducing speed? max flow rate? PA factor? Hmmmm
