I haven’t previously imported the tools into F360, so I just tried now. Nothing imported.
So, standing on the shoulders of this thread: Tool file for Fusion 360 CNC is empty
Change the .tools file to .zip, open, extract tools.json. Open tools.json in Notepad++ or your favorite text editor and replace all 默认预设 with Default preset
Then you can import the tools.json file into Fusion360
Alternatively, here’s the file I just edited, you should be able to import this: Snapmaker 2.0 CNC Tool Library.json (28.1 KB)
