It is possible to upgrade to the Prusa CORE One from MK4S, MK4, MK3.9S, MK3.9, and MK3S+ printers. However, each model has a different method, and some models must be upgraded to the S series. Additionally, some parts may need to be purchased.
A direct upgrade to the Prusa CORE One is only feasible for the MK4S using the MK4S to Prusa CORE One Conversion kit.

Verify the version of your printer's PSU. Two versions are possible: black or silver.

| Current printer | Upgrade path |
|---|---|
| MK4S | MK4S to CORE One Conversion Kit |
| MK4 | MK4 to MK4S, then MK4S to CORE One Conversion Kit |
| MK3.9S | X motor, Y motor (400 steps), then MK4S to CORE One Conversion Kit |
| MK3.9 | X motor, Y motor (400 steps), MK4 to MK4S, then MK4S to CORE One Conversion Kit |
