                  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. 

                  Due to the number of changes in the components, it is not worthwhile to convert MK3.5 and MK3.5S to CORE One, we do not have an upgrade path from these models. 
                  In that case, we recommend directly purchasing the CORE One. 

                  A direct upgrade to the Prusa CORE One is only feasible for the MK4S using the MK4S to Prusa CORE One Conversion kit.

                  Upgrade paths to Prusa CORE One

                  Preliminary check - PSU version

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

                  An upgrade to CORE One is possible only with the black version of the PSU. If a silver PSU is equipped on your printer, it is necessary to replace it with a black PSU, together with 2x PSU-xBuddy power cable and 1x power panic cable.

                  Is it possible to make the core one upgrade kit for the new LCD work with a MK4S with the old LCD. If so, what additional parts would be needed.
