Printer Connection Setup

Connection settings are saved per printer. Open 3D Printer, find the printer card, choose Settings, then use Connection to pick firmware, transport, host, and reconnect behavior.

Setup Flow

  1. Apply a printer preset if one matches the machine.
  2. Choose the board firmware.
  3. Choose Network or USB transport.
  4. Fill the required host, password, or serial fields.
  5. Run Test Connection.
  6. Use Connect only after the test succeeds.

Presets

Presets patch common defaults such as board type, baud rate, build volume, and kinematics. They do not save or connect automatically.

Use Custom when you want to leave existing values unchanged.

Firmware Type

The board type controls which API and object model Cindr3D expects.

Supported paths include Duet/RRF, Klipper, Marlin, Smoothieware, grbl, Repetier, and generic G-code transport. Choosing the wrong firmware type is the most common setup mistake.

Network Setup

For network mode, enter the hostname or IP without extra path text. Use a raw IP address when .local names are unreliable.

Examples:

  • 192.168.1.100
  • myprinter.local
  • klipper.home

Duet Standalone vs SBC

Duet/RRF printers have an extra mode selector.

Cindr3D Duet connection mode

Standalone means the Duet board serves HTTP/WebSocket directly. SBC means Duet Software Framework runs on a Raspberry Pi or similar board connected to the Duet.

USB Setup

USB mode uses Web Serial from a Chromium browser over HTTPS or localhost.

Cindr3D USB connection setup

Requirements:

  • Chrome, Edge, Brave, Arc, or another Chromium browser.
  • A real USB data cable.
  • The correct baud rate for the firmware.
  • No other application currently holding the serial port.

USB is useful for direct G-code transport, but network mode is required for richer file listings, object models, graphs, height maps, and firmware-specific dashboards.

Test, Then Connect

Always run Test Connection first. It verifies host, firmware type, and password without opening the persistent live session.

Common failures:

  • Connection refused: wrong IP/host, printer off, or service not running.
  • Unauthorized: wrong password or token.
  • Timeout: network route, firewall, Wi-Fi, or printer service issue.
  • Garbled USB output: wrong baud rate.
