I did it with 2.3 Thank you @DaHai8. Could you please guide (or help) me generate for bed 200x200x300, it's my delta bed size? Thank you again !

Yes, I modified your json a little because I found some errors on log file (cura.log) 1. Version : 2-> 1 2. platform: use prusai3 stl file.

I can't choose your printer after add this json file to Cura folder. I also try to replace code in defined profiles but nothing changes. Am I wrong at something ?

Hi DaHai8, I tried your guide but nothing changes, Could you please share your json file ? Thanks.
