Does the Anycubic Kobra S1 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
SimplyPrint Client
Compatible
What you need: A computer or Raspberry Pi on the same network that stays on, running the SimplyPrint Client
Connected through Klipper (Moonraker), SimplyPrint supports most of what it offers on the Anycubic Kobra S1: the camera and AI failure detection, remote printing, skipping objects, temperature and movement control and AutoPrint. Not yet in SimplyPrint through Klipper (Moonraker): download the file before the print starts. Not available through Klipper (Moonraker): map filament to multi-material slots and sync loaded filament from the multi-material unit. The table below compares the two ways of connecting it to SimplyPrint.

What slicer to use for the Anycubic Kobra S1
Use OrcaSlicer, ElegooSlicer, or Cura: each has a ready-made profile for the Anycubic Kobra S1.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Anycubic Kobra S1.
Cloud-Based Slicer for Anycubic Kobra S1: Use OrcaSlicer Online
Use OrcaSlicer and other slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your Anycubic Kobra S1 models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Anycubic Kobra S1: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the Anycubic Kobra S1
SimplyPrint works as the Anycubic Kobra S1's app: on your phone and in any browser, with a slicer in the cloud.
There's no plate swapper or auto-ejection kit for the Anycubic Kobra S1 in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
Enclosed printers push their prints out
The Anycubic Kobra S1's bed only moves up and down inside its enclosure, so instead of swapping plates, a push-off routine lets the toolhead push the cooled print off the plate and out through its front door, which has to be open while it runs. Some printers won't print with the door open (the Prusa CORE One has a door sensor), so check yours first.
Ways to automate it
Push prints off with the toolheadOn a CoreXY printer, a G-code routine can push the cooled print off the front of the plate before the next job starts.
Your own ejection G-codeWrite the routine that clears your plate, and AutoPrint runs it after every print.

Suitability
Notes
PLA
Great
On the maker's list of materials for this printer.
PETG
Great
On the maker's list of materials for this printer.
TPU & flexibles
Great
On the maker's list of materials for this printer.
ABS & ASA
Great
On the maker's list of materials for this printer.
Nylon (PA)
Good
Doable with care - dry the filament thoroughly, and an enclosure helps a lot.
Polycarbonate (PC)
Good
In range for PC. Dry the filament, print slowly, and use an enclosure for the best results.
Carbon-fiber & glass-filled
With care
Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
Best filament for the Anycubic Kobra S1
Filaments the Anycubic Kobra S1 prints well, Anycubic's own first, then the best known.
Praises its mechanical reliability and the ACE Pro with built-in dryer, though swaps are a little slow and purge waste cannot be adjusted in the slicer. Judges it cheaper than the Bambu Lab P1S Combo but limited by software.
“this is an excellent printer, limited by the software.”
Aurora Tech · May 13, 2025
Tests the $699 Kobra S1 with enclosure and ACE Pro. Well-built hardware, and the ACE Pro stands out for filament compatibility, reliability and the dryer; he would rank it higher with full Orca Slicer support and open Mainsail or Fluidd access.

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.
Firmware and custom 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]
Local control and integrations ●●●●●
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]
Third-party filament, slicers and parts ●●●●●
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]
Repairs and spare parts ●●●●●
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]
Data and privacy ●●●●●
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 and documentation ●●●●●
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]
Pros
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.
Cons
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).
Track record
October 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]
October 2024: Anycubic published the Kobra 3 firmware sources (Klipper-go, MCU firmware, Linux kernel and U-Boot) on GitHub under GPL-3.0.
[1]
February 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.
