Anycubic is a Chinese 3D printer maker founded in 2015. It sells the Kobra line of FDM printers, including the enclosed Kobra S1 and S1 Max, the large Kobra 3 Max and the low-cost Kobra X, the ACE Pro multi-material unit and Photon resin printers. Its printers are aimed at hobbyists and home users at budget to mid-range prices.

Gegründet: 2015 · Hauptsitz: China (its global store is run by Hongkong Anycubic Technology Co., Limited) · Website: www.anycubic.com

Anycubic is mixed: its printers work locally in LAN mode, take third-party filament and slicers, and have spare parts and guides, but its published firmware source leaves proprietary parts closed, custom firmware is unsupported, and its cloud had a security incident in 2024.

Firmware und angepasste Firmware
●●●●●		 The Kobra 3, 3 Max and S1 run Klipper-go, Anycubic's Go port of Klipper. Anycubic published its source with the kernel and U-Boot under GPL, for the Kobra 3 in October 2024 and for the wider family in October 2025, but says some proprietary features are kept closed, and that modifying the firmware voids the warranty. The community project Rinkhals adds Fluidd, Mainsail and SSH, and reports that the newer Kobra X only accepts signed updates. [1][2][3]
Lokale Steuerung und Integrationen
●●●●●		 LAN mode lets Anycubic Slicer Next send prints, show progress and stream video on the local network without an account, and the S1's firmware 2.5.9.9 added sending from OrcaSlicer. With LAN mode on, the cloud, the app and AI failure detection are off, and the S1 must leave LAN mode and be bound to an account to update its firmware. Anycubic documents no local API for other software; Moonraker, Fluidd and Mainsail come only with the community firmware Rinkhals. [4][5][3]
Filament, Slicer und Teile von Drittanbietern
●●●●●		 Third-party filament works. Anycubic Slicer Next is an open-source OrcaSlicer fork, and recent firmware accepts files sent from OrcaSlicer. Hotends, extruders and many other parts are model-specific Anycubic parts. [6][5][7]
Reparaturen und Ersatzteile
●●●●●		 Anycubic's store sells hotends, extruders, motherboards, heated beds, motors and screens, and its wiki has replacement guides for current models, for example the Kobra S1 Max XY motors and the Kobra X Y-axis motor. [7][8][9]
Daten und Datenschutz
●●●●●		 LAN mode keeps data on the local network, but the app and cloud need an account. Anycubic's privacy policy allows broad collection, including product usage, device signals and nearby Wi-Fi access points, and storage in the United States. In February 2024 a flaw in its cloud MQTT server let a third party push a file to Kobra 2 printers; Anycubic apologised and patched it. [10][11][4]
Community und Dokumentation
●●●●●		 Active user community and a wiki with guides and error codes for each model. Source releases leave proprietary parts closed, and custom firmware is a community effort. [4][2][3]
Vorteile
  • Budget to mid-range prices, with multi-colour Combo bundles.
  • LAN mode works without an account.
  • Spare parts and replacement guides for current models.
  • Open-source slicer, and third-party filament works.
Nachteile
  • Published firmware source leaves some features closed; modifying firmware voids the warranty.
  • LAN mode turns off the app, cloud and AI failure detection, and firmware updates need the cloud.
  • The privacy policy allows broad data collection.
  • Its cloud was used to push files to printers in 2024 (fixed).
Erfolgsbilanz
  • Oktober 2025: Anycubic published Klipper-go, its Go port of Klipper, as a standalone project for the Kobra 3, Kobra 3 V2, Kobra 3 Max and Kobra S1, with the MCU firmware, Linux kernel and U-Boot sources, on GitHub under GPL-3.0. It says some proprietary features remain closed. [2][12]
  • Oktober 2024: Anycubic published the Kobra 3 firmware sources (Klipper-go, MCU firmware, Linux kernel and U-Boot) on GitHub under GPL-3.0. [1]
  • Februar 2024: A third party used a vulnerability in Anycubic's cloud MQTT server to make Kobra 2 Pro/Plus/Max printers download a file named 'hacked_machine_readme.gcode'. Anycubic counted 237 affected printers and over 2,000 that received the file, apologised for its late response, tightened cloud authorisation and released a firmware fix. [11]
