Does the Flying Bear 4s 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd? Each way of connecting it, what it needs, and how to set it up.

What works with SimplyPrint

Connected through Klipper (Moonraker), SimplyPrint supports most of what it offers on the Flying Bear 4s: 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): print binary G-code (.bgcode). The table below compares the two ways of connecting it to SimplyPrint.

What slicer to use for the Flying Bear 4s

None of the slicers in SimplyPrint's cloud has a ready-made profile for the Flying Bear 4s, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match.

No profile for the Flying Bear 4s

We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Flying Bear 4s.

Profiles and other slicers

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 Flying Bear 4s: 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 Flying Bear 4s

SimplyPrint works as the Flying Bear 4s's app: on your phone and in any browser, with a slicer in the cloud.

What you get with SimplyPrint

  • An app for iPhone and Android, the same in any browser, and a slicer in the cloud.
  • More than monitoring: a print queue, AI failure detection, AutoPrint and accounts for a team.
  • Printers from many brands in one place, side by side.
  • A European cloud: hosted in Frankfurt, Germany, under the GDPR.

What filament can the Flying Bear 4s print?

Filament compatibility for the Flying Bear 4s: the materials it can handle, judged from its hotend, bed, chamber and enclosure.

Filament Suitability Notes
PLA Great The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required.
PETG Great Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed).
TPU & flexibles With care Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU.
ABS & ASA With care The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints.
Nylon (PA) With care Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC) Not ideal Not recommended - PC needs very high hotend temps and an enclosed chamber.
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.

What filament can the Flying Bear 4s print?

Based on its specs (hotend up to 260C, heated bed up to 110C), the Flying Bear 4s handles PLA or PETG well. See the full filament guide above for ABS, nylon, PC and composites.

Does the Flying Bear 4s work with OctoPrint or Klipper?

The Flying Bear 4s works with OctoPrint or Klipper (Mainsail and Fluidd), and SimplyPrint connects to it through them - so you get cloud access, a queue and camera monitoring on top.

The Flying Bear 4s has a 275 x 210 mm print bed and prints up to 210 mm tall, a build volume of about 275 x 210 x 210 mm. See the full specifications table above for bed type, temperatures and more.

Can the Flying Bear 4s eject prints automatically?

There's no kit for it that we support yet, but SimplyPrint's AutoPrint can run your own ejection G-code, work with a robot arm through the API, or wait for you to clear the plate, and then start the next job from your queue.
