FlashForge Python API

Python library for controlling FlashForge 3D printers with async support for the modern HTTP API and the legacy TCP protocol.

Supported Printers

Installation

pip install flashforge-python-api

Quick Start

Modern LAN-mode HTTP printers require:

• printer IP address
• serial number
• check code (per-printer credential, not returned by discovery)

import asyncio
import os
from flashforge import FlashForgeClient, FiveMClientConnectionOptions, PrinterDiscovery


async def main():
    check_code = os.getenv("FLASHFORGE_CHECK_CODE", "").strip()
    if not check_code:
        print("Set FLASHFORGE_CHECK_CODE before running this example")
        return

    discovery = PrinterDiscovery()
    printers = await discovery.discover()

    if not printers:
        print("No printers found")
        return

    printer = printers[0]
    if not printer.serial_number:
        print("Discovered printer did not report a serial number")
        return

    options = FiveMClientConnectionOptions(
        http_port=printer.event_port,
        tcp_port=printer.command_port,
    )

    async with FlashForgeClient(
        printer.ip_address,
        printer.serial_number,
        check_code,
        options=options,
    ) as client:
        status = await client.get_printer_status()
        if not status:
            return

        await client.init_control()

        status = await client.get_printer_status()
        print(f"Printer: {client.printer_name}")
        print(f"State: {status.machine_state if status else 'unknown'}")

        await client.control.home_axes()


asyncio.run(main())

Main Entry Points

• FlashForgeClient: primary client for modern printers
• PrinterDiscovery: recommended discovery API
• FlashForgeA4Client: documented TCP client for Adventurer 4 Lite / Pro printers
• FlashForgeA3Client: documented TCP client for Adventurer 3 printers
• FlashForgeTcpClient and client.tcp_client: lower-level TCP access for direct commands and generic legacy workflows

Capabilities

• printer discovery
• printer status and machine information
• job control
• file listing, uploads, and thumbnails
• temperature and motion control, including per-nozzle and chamber temperature control (Creator 5)
• LED, camera, and filtration control where supported
• AD5X and Creator 5 / Creator 5 Pro material-station, slot configuration, and material mapping
