Prusa MK4S to CORE One+ Gen 2 Conversion Kit

What's New in the CORE One+

The Prusa CORE One+ is the next evolution of our proven workhorse. It integrates key hardware quality-of-life improvements adopted from the CORE One L, combined with all the firmware updates developed over the entire lifespan of the CORE One.

This combination delivers the best print quality, smoother operation, and a more autonomous, hassle-free user experience.

Key features:

• Automatic Top Vent Operation: The extruder now automatically opens the vent for low-temp materials (PLA/PETG) and closes it for high-temperature materials, ensuring the optimal thermal environment and creating a true "set-and-forget" experience.
• Easy Flex Loading: A redesigned filament insertion point makes the process of feeding flexible filaments quick and simple.
• New Bayonet-Style Spoolholder: Allows you to use various spool sizes. Ready for a direct-feed drybox.
• Firmware & Performance: Includes all software updates from the entire lifespan of the CORE One, resulting in even better print quality and smoother operation right out of the box.

Transform your Original Prusa MK4S into the brand new, fully enclosed CoreXY 3D printer and upgrade your printing experience. Once you’re finished with the assembly, your new printer is going to be not only faster, but it will also take up less space, print larger models and tackle even demanding filaments like PCCF or Nylon without warping. In the Conversion Kit, you will find everything you need to perform the entire process and end up with the Prusa CORE One+ without any compromise.

The Prusa CORE One+ utilizes many proven parts from the Original Prusa MK4S. This is why it is possible to convert your existing 3D printer into the new Prusa CORE One+, and also why we can offer outstanding backwards compatibility. You can easily reuse your current print sheets, hotends, nozzles, and many other parts.
