Setup for printers running Klipper

This setup is for 3D printers that run the popular Klipper firmware with Mainsail, Fluidd, or Moonraker installed.

How do I know if my printer runs Klipper?

If your printer has smart features like a touchscreen, web interface (Mainsail or Fluidd), or the manufacturer specifically mentions Klipper in the specifications, it's likely running Klipper.

Examples of printer brands and models that ship with Klipper:

  • Voron - All Voron printers
  • RatRig - All RatRig printers
  • Sovol - SVO7 Series
  • Biqu - Huraken
  • Kingroon - KLP1, KP3S Pro V2
  • FLSun - V400
  • Prusa - Pro HT90
  • & many other modern 3D printers

Requirements for this setup

Your Klipper printer needs:

Web Interface

Your printer must use Mainsail or Fluidd web interface, OR have Moonraker installed standalone.

Moonraker Version

Your Moonraker version must be v0.8.0 or newer (released Feb 11, 2023). Most modern printers ship with a modern Moonraker version.

How to check your Moonraker version:

  • In Mainsail/Fluidd: Go to Machine / Settings → System / Software updates → Update Manager / Software Updates
  • Or visit http://yourprinter.local:7125 in your browser
  • Note: Some manufacturers may remove access to version information in their custom builds
  • Caution: If your printer doesn't run stock Klipper, be careful about updating Moonraker - some printers can't handle updates. Research your specific model before updating.
Official Moonraker

Must be the official version of Moonraker, not a manufacturer-modified "fork" where SimplyPrint support may have been removed.

Don't meet these requirements?

If your Moonraker version is older than v0.8.0, the version doesn't show up at all, or you have a manufacturer-modified Moonraker that doesn't support [simplyprint] - and you have SSH access to your printer - you can use our SSH setup script instead. It installs a fresh Moonraker with SimplyPrint support alongside your existing setup.

Thousands complete this setup every week. Follow each step carefully - most issues come from skipping ahead.

Why some setups are tricky: Some manufacturers lock down their printers, requiring workarounds like custom firmware. If hardware is listed as required, there's no shortcut.

Common Questions

If your printer has a touchscreen and you can access a web interface (Mainsail or Fluidd) by typing its IP address in a browser, it probably runs Klipper. Common Klipper printers include: Creality K1/K2, Sovol SV07, FLSUN V400, Voron, etc.
Try these steps: 1) Make sure you saved the file AND restarted Moonraker, 2) Check for typos - it must be exactly [simplyprint] on its own line, 3) Check the Pending Printers section in SimplyPrint, 4) Verify Moonraker is running (check your web interface).
Moonraker is the API server that lets external software (like SimplyPrint) communicate with Klipper. It runs alongside Klipper on your printer. If you have Mainsail or Fluidd, you already have Moonraker.
SimplyPrint requires Moonraker v0.8.0 or newer. Update Moonraker through your printer's web interface (Machine → Update Manager in Mainsail, or Settings → Software Updates in Fluidd).
No! If your printer already runs Klipper, everything is built-in. Just add [simplyprint] to your config and you're done.
