PA6-CF Printing temperature (forum.guncadindex.com)

I was wondering if there is consensus in the community on the PA6-CF printing temperature. Manufacturers seem to cap at 300 (280-300 range). There is a user on other resource advocating for 320c for printing Fiberon PA6-CF citing good layer adhesion. How much merit does this theory actually have ?

Is there a limit after which temperature become detrimental ? Doing some quick searches looks like injection molding of nylon is using standard 280-300c temperature so that leads me to believe that printing hot may not be a good idea unless we do actual layer adhesion tests and not just "it looks better"

Take other people's print temps with a grain of salt. Extruder thermistors aren't individually calibrated, different nozzle types have different heat transfer efficiency, and high volumetric rates reduce effective filament temperature due to reduced heating time.

Start with the manufacture max and run some tests at elevated temperatures to see if it results in any improvement in layer adhesion. You don't need sophisticated test apparatus, just print some "snap sticks" and see if you can feel a difference breaking them.
