Hi, I use the system preset for eSun PLA+ filament. The one that is available in the printer screen and Bambu Studio by default, not a custom filament.
If I use the nozzle 0.4 with eSun PLA+ filament, there is no problem, but if I use the 0.2 nozzle, when I choose eSun PLA+ filament, the max volumetric speed is set to 1. The default for the 0.4 nozzle and 16.
The bug is in the Bambu Studio or in the X1C firmware ? I know I can change manually, but each time and change a roll, I need to modify it.
The default presets can be found using the Help menu in Studio with “Show Configuration Folder”. In Windows, drill down to C:\Users%username%\AppData\Roaming\BambuStudio\system\BBL\filament. and edit “eSUN PLA+ @BBL A1 0.2 nozzle.json”.
But you will need to repeat the procedure with every Studio update, which will replace all the default presets ( and might correct the max volume for this filament). Creating a User Preset would be more reliable and eliminate the need to keep changing the default.
