Automate the Prusa MK4
Plate swappers and auto-ejection kits made for the Prusa MK4 work with SimplyPrint's AutoPrint: after each print the plate is cleared and the next job starts from your queue, so it keeps printing on its own.
Other ways to automate it
- Your own ejection G-code Write the routine that clears your plate, and AutoPrint runs it after every print.
- A robot arm, or anything with an API Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system.
- Clear it by hand, keep the queue AutoPrint waits for you to mark the plate clear, then starts the next job.
AutoPrint comes with the Pro plan and up.

What filament can the Prusa MK4 print?
Filament compatibility for the Prusa MK4: 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 | Great | The direct-drive extruder feeds flexible filament well. Print slowly for clean results. |
| 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) | With care | On the edge - PC really wants an enclosed, hot chamber to avoid warping. |
| 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.

Can I use OrcaSlicer with the Prusa MK4?
Yes. OrcaSlicer comes with a profile for the Prusa MK4, and you can run it in SimplyPrint's online slicer, so there's nothing to install.
What filament can the Prusa MK4 print?
Based on its specs (hotend up to 300C, heated bed up to 120C), the Prusa MK4 handles PLA, PETG, or TPU & flexibles well. See the full filament guide above for ABS, nylon, PC and composites.
Does the Prusa MK4 work with OctoPrint or Klipper?
The Prusa MK4 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.
What is the Prusa MK4's bed size and build volume?
The Prusa MK4 has a 250 x 210 mm print bed and prints up to 220 mm tall, a build volume of about 250 x 210 x 220 mm. See the full specifications table above for bed type, temperatures and more.
Can the Prusa MK4 eject prints automatically?
Yes, with an AutoPrint kit made for it: Prusa MK4 JobOx. SimplyPrint's AutoPrint then starts the next job from your queue each time the plate is clear, so it keeps printing on its own.
