Changing Initial Layer Speed Default

I can change the Initial Layer speed as shown below but is there a way to change the default so that it populates with say 30? There is probably a settings or gcode file somewhere.

Studio does not allow editing the System presets without changing the name, which creates a User preset.

Like any other process setting, change the speed, save as a User preset with a new name, use that User preset in the future.

It is possible to edit the .json files of the System presets with a text editor, but the changes will be overwritten with every update.

Thanks. I see how to create a user preset now. I created filament user files which is similar.

Have a path to those .json files?

Easiest way to locate the .json files is to use Help>Show configuration folder.

The System process presets on my Windows PC are in C:\Users\%username%\AppData\Roaming\BambuStudio\system\BBL\process\

That’s a hidden directory, I find accessing it through the Help menu is just easier than drilling down in Explorer.

I have an A1. In the file named “0.20mm Standard @BBL A1.json” in that directory, initial layer speed isn’t there (not much there). However, the corresponding P2S file has lots of things including initial layer speed. Happen to know what file to edit for A1?

Try the “inherits” process, C:\Users\lk\AppData\Roaming\BambuStudio\system\BBL\process\fdm_process_single_0.20.json

Probably need to restart Studio after editing the .json.

Remember to re-edit if/when you update Studio.
