The Kobra 3 Max V2 Combo is Anycubic's large open-frame bedslinger: a 420 x 420 x 500 mm volume, a 600 mm/s top speed and the ACE 2 Pro filament unit in the box for four-colour printing. It is for hobbyists and small shops that want big or many parts in PLA, PETG and TPU at a modest price.
Choose the Kobra 3 Max V2 Combo when plate size matters more than anything else and you print PLA, PETG or TPU: Anycubic lists the Combo at $619 with an ACE 2 Pro, or $459 for the Max V2 without it. It is a new, untested model and we found no independent review of it; Tom's Hardware tested the ACE 2 Pro on the smaller Kobra 4 Combo and found filament swaps slow and purging wasteful, so expect the same from the unit here. It is open, so ABS and ASA are not what it is made for; for those, an enclosed printer such as the Bambu Lab P2S is the better pick. If you do not need the volume, the Kobra 4 Combo costs less.
优点
A 420 x 420 x 500 mm volume, which Anycubic puts at 88 L, so large parts print in one piece (Anycubic).
Comes with the ACE 2 Pro for four colours, with drying at up to 65 degrees C while printing; a second unit adds up to eight colours (Anycubic).
A quick-release all-metal hotend with a hardened steel nozzle, up to 300 degrees C, and a 600 mm/s top speed (Anycubic).
Auto-levelling, a dual Y-axis motor and belt tensioning help prints land the same way every time (Anycubic).
Expected to work with SimplyPrint through the SimplyPrint Client.
缺点
Open frame with no enclosure, and a 300 degrees C hotend aimed at PLA, PETG and TPU, so ABS and ASA are a poor fit.
No built-in camera in our facts, so remote watching needs an add-on.
ACE 2 Pro swaps are slow and purge a lot of filament (Tom's Hardware, on the Kobra 4 Combo), and the ACE Pro and ACE 2 Pro cannot be used together (Anycubic).
New and without an independent review yet; the SimplyPrint Client route is expected, not yet verified.
适合谁
学校不太适合
A large open bedslinger with a hot nozzle and moving bed in reach is a poor classroom machine, even though SimplyPrint can queue student prints for approval.
业余爱好者适合
Large volume and four-colour printing for a modest price, though untested by reviewers and slow at colour changes.
企业可用
The volume helps for big prototypes in PLA and PETG, but it is open, new and limited in materials.
打印农场可用
Large plate per machine and low price, but no camera, no enclosure and no track record for unattended runs.

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.

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.
固件和自定义固件 ●●●●●
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]
本地控制与集成 ●●●●●
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]
第三方耗材、切片软件和零件 ●●●●●
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]
维修和备件 ●●●●●
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]
数据与隐私 ●●●●●
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]
社区和文档 ●●●●●
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]
优点
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.
缺点
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).
实绩
十月 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]
十月 2024: Anycubic published the Kobra 3 firmware sources (Klipper-go, MCU firmware, Linux kernel and U-Boot) on GitHub under GPL-3.0.
[1]
二月 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.
