Custom Snapmaker U1 Firmware

SSH Access

Available in: Basic and Extended firmware

The custom firmware enables SSH access to the Snapmaker U1 printer.

Configuration (Extended Firmware)

In Extended firmware, SSH is disabled by default and can be enabled via the firmware-config web UI or by editing extended2.cfg:

[remote_access]
ssh: true

Changes take effect after restarting the SSH service or rebooting the printer.

Credentials

• User: root / Password: snapmaker
• User: lava / Password: snapmaker

Connecting

ssh root@<printer-ip>

Replace <printer-ip> with your printer’s IP address.

Changing Passwords

To persist password changes across reboots, enable data persistence. See Data Persistence.

Security Considerations

• SSH provides full system access to your printer
• Only enable SSH on trusted networks
• Consider disabling SSH when not actively needed
• Change default credentials after first login
