Carbide Create runs in 3 different modes:
- Free — this is the default and lacks 3D modeling but can generate G-Code http://carbide3d.com/blog/2017/big-carbide-create-update-its-now-free/
- Trial — this is enabled by Help | Enable Pro Trial and can be disabled by Help | Disable Pro Trial
- Pro — this requires a license from launch.carbide3d.com (note that this uses a different account than other Carbide 3D sites) but see: Carbide Create Pro - Free For a Year — you can paste in the license via Help | Register
https://launch.carbide3d.com — creating an account will allow a free trial. “This trial is fully functional … so you can generate G-Code and try a full project.”
