If you are locked out, the most reliable path is to check the original manual or the digital backup folder (often named "Parameters" or "Vendor") that came on the USB drive with the machine. If the default 8888 doesn't work, reaching out to the specific machine distributor with your serial number is the best way to retrieve the unique factory code.

Q: Does SmartCarve 4.3 store passwords in plain text? A: In older versions (pre-2019), some user-config files stored passwords in plain text. In newer 4.3 builds, they are hashed but still vulnerable to local decryption if someone has physical access to your PC.
Q: Why does SmartCarve 4.3 ask for a password when I try to change the language? A: That is unusual. Typically, language settings do not require a password. If this happens, your software may be a customized build from a vendor who locked all configuration menus. Use the manufacturer password to unlock.
