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.

Using firmware-config Web UI (preferred)

Navigate to the firmware-config web interface, go to the Remote Access section, and enable SSH Access.

Manual Setup (advanced)

Step 1: Edit /home/lava/printer_data/config/extended/extended2.cfg to enable SSH:

[remote_access]
ssh: true

Step 2: Reboot the printer for changes to take effect.

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
