Core hardware and replacement boundaries
The captured U.S. specifications confirm the enclosed CoreXY construction and the build and temperature limits above. A 0.4 mm hotend is included, with 0.25, 0.6 and 0.8 mm documented as options. Use a Kobra S1 quick-release hotend and a replacement PEI spring-steel plate matched to Kobra S1 dimensions.
Anycubic Kobra S1 has the following documented build volume: 250 × 250 × 250 mm. A usable build volume sets the boundary for the object you plan to print. Compare the part in its intended orientation with this envelope before choosing the machine. This measurement is different from the printer’s outside dimensions: fitting the printer on a desk does not establish that a particular part fits inside it.
Anycubic Kobra S1 has the following documented enclosed corexy construction: yes. The same configuration lists primary supported filaments as PLA · PETG · TPU · ABS · ASA. Keep the chamber claim separate from nozzle and bed temperatures. An enclosure, an actively heated chamber and an “up to” chamber-temperature statement are not interchangeable descriptions. For the configuration documented here, check the material guidance and any stated conditions; the chamber entry alone is not evidence that every job reaches the listed maximum.
Anycubic Kobra S1 has the following documented maximum nozzle temperature: 320 °C. The same configuration lists primary supported filaments as PLA · PETG · TPU · ABS · ASA. A hotend temperature ceiling is an operating limit, not a complete material-compatibility list or the setting for every print. Read it alongside this model’s documented filament guidance, nozzle configuration and print profiles. The maximum alone does not establish that an enclosure-dependent, abrasive or otherwise restricted material has been approved for this configuration.
Anycubic Kobra S1 has the following documented maximum bed temperature: 120 °C. The same configuration lists maximum nozzle temperature as 320 °C. Treat the bed limit separately from the hotend limit and the installed print surface. Those entries answer different questions, so a higher nozzle maximum does not automatically give the bed or surface the same capability. Use the documented material and surface combination when selecting a print profile rather than treating the maximum as a universal adhesion setting.
Anycubic Kobra S1 has the following documented supported nozzle sizes: 0.25 mm · 0.4 mm (included) · 0.6 mm · 0.8 mm. The same configuration lists primary supported filaments as PLA · PETG · TPU · ABS · ASA. Identify the installed nozzle and the exact documented replacement route before changing a print profile or ordering a spare. Diameter, material and printer-family fit are separate parts of that check. A listed option is not necessarily included in the box, and an accessory for another toolhead cannot be declared interchangeable from its appearance or nominal diameter alone.
- Build volume: 250 × 250 × 250 mm
- Maximum nozzle / bed temperature: 320 °C / 120 °C
- Documented hotend sizes: 0.25, 0.4, 0.6 and 0.8 mm
Materials, ACE Pro and software
The primary U.S. list contains PLA, PETG, TPU, ABS and ASA. Kobra S1 can use first-generation ACE Pro only under its documented color and filament conditions. Anycubic Slicer Next is the named slicer, and the Anycubic App is documented for remote control, monitoring and print records; printer controls and USB print remain separate routes.
Anycubic Kobra S1 has the following documented primary supported filaments: PLA · PETG · TPU · ABS · ASA. The same configuration lists supported nozzle sizes as 0.25 mm · 0.4 mm (included) · 0.6 mm · 0.8 mm. The documented material wording is the useful boundary for selecting filament. Preserve distinctions such as ideal, capable, not recommended and supported only under stated conditions. Do not turn a broad temperature specification into permission to use an unlisted material, and do not assume that support at the printer means support through every optional material feeder.
Anycubic Kobra S1 has the following documented software and control routes: Anycubic Slicer Next · Anycubic App · printer controls · USB print. The same configuration lists build volume as 250 × 250 × 250 mm. Use the named software and transfer route for the actual configuration documented here. Sending a file, preparing a sliced job and controlling the device are different steps; availability of one route does not confirm every other function. Check the manufacturer’s version and interface conditions before moving a workflow from a neighboring model or an older installation.
Ownership and maintenance
For Anycubic Kobra S1, Hotend removal safety: Let filament cool completely before removing or unplugging the hotend; premature removal can lodge cooled filament in the throat. Build the care routine from this model’s documented tasks and stop conditions, keeping any interval tied to the part it concerns. Automatic operation does not authorize skipping checks or using an unlisted service method. If the source names abnormal wear, damage, obstruction or electrical precautions, retain those boundaries and use official support when the situation falls outside the documented procedure.

FAQ
Anycubic Kobra S1 frequently asked questions
Each answer stays within the facts and sources shown on this page.
01What are Kobra S1's documented build volume and primary filament families?
Anycubic documents a 250 × 250 × 250 mm fully enclosed CoreXY printer and lists PLA, PETG, TPU, ABS and ASA in the main specifications. Treat other high-temperature claims separately unless their exact conditions are captured.
02Which nozzle sizes does Anycubic list for Kobra S1?
The product specifications list a standard 0.4 mm hotend and optional 0.25, 0.6 and 0.8 mm sizes. Match the replacement to Kobra S1 and follow the full-cooldown rule before removal.
