Anycubic Kobra X, Kobra S1 and Kobra 3: connecting and which file types work
Anycubic Kobra X, Kobra S1 and Kobra 3 printers connect to SimplyPrint through the SimplyPrint Client, and some also through community firmware. Not every model accepts every file type. This guide covers how each model connects, which files it can print, and what to send when a file is refused.

How each model connects
Model | SimplyPrint Client | Klipper with Rinkhals community firmware |
|---|---|---|
Kobra X | ✓ | ✗ |
Kobra S1, Kobra S1 Max | ✓ | ✓ |
Kobra 3 V2, Kobra 3 Max | ✓ | ✓ |
Kobra 3 (first generation) | Not yet | ✓ |
Combo versions connect the same way. The SimplyPrint Client also supports the Kobra 2 Pro, Kobra 2 Plus and Kobra 2 Max.
With the Client nothing is installed on the printer:
- In the SimplyPrint Client, choose Add printer > Anycubic.
- Pick your printer from the list the Client finds, or enter its IP address. There is no access code.
- Enter the setup code the Client shows in SimplyPrint.
Check: the printer shows as online in SimplyPrint.
Which file types work
Model | .gcode | Sliced 3MF (.gcode.3mf) |
|---|---|---|
Kobra X | ✓ | ✗ |
Kobra S1, Kobra S1 Max | ✓ | ✗ |
Kobra 3 V2, Kobra 3 Max | ✓ | ✓ if the firmware supports it |
These are for printers connected through the SimplyPrint Client. Before sending a .gcode.3mf, the Client checks that the printer's firmware reports 3MF support. If it does not, the upload stops with "This printer does not support printing .3mf files"; send a plain .gcode instead.
SimplyPrint does not send a .gcode.3mf to a Kobra X or Kobra S1: their firmware cannot reliably print one. Such a file shows as not supported for those printers. Send a plain .gcode instead.
Get a plain .gcode file
- Slice it in the Cloud Slicer: pick your Kobra X or Kobra S1 as the printer and slice. The Cloud Slicer saves a plain .gcode for these printers by itself, because SimplyPrint knows they can't print a .gcode.3mf.
- From a .gcode.3mf you already have: a sliced 3MF holds the G-code for each plate inside it. Open the .gcode.3mf with a zip tool (rename it to .zip first if your computer will not open it) and take the plate's G-code from the Metadata folder, for example plate_1.gcode. Upload that file.
- From OrcaSlicer on your computer: in the printer settings, turn off Use 3MF instead of G-code (Basic information > Advanced), then slice and export again.
- From Anycubic Slicer Next: export a .gcode. Use it if a file from OrcaSlicer is refused: OrcaSlicer has sometimes produced Anycubic files the printer won't accept.
Check: the file in SimplyPrint ends in .gcode and can be started on the printer.
Slicing for Anycubic
The Cloud Slicer has no Anycubic Slicer Next engine; it slices Anycubic printers with its OrcaSlicer engine. For a Kobra X or Kobra S1 the result is always a plain .gcode. For a Kobra 3 connected through the SimplyPrint Client it is a sliced 3MF (.gcode.3mf), which the printer can print if its firmware supports 3MF (see above).
If the printer refuses a file with "The device cannot parse the file" or "Task abnormally ended", see My print didn't start: errors the printer reports.
