Step 1 Preparing the upgrade kit
⬢Welcome to the tutorial how to upgrade your Original Prusa i3 MK2/S to Original Prusa i3 MK3S. Please prepare the upgrade kit received from Prusa Research. Your package includes one orange and black PETG spool or two black spools. This depends on your previous order.
⬢The upgrade kit does not include all the parts needed to build MK3S, therefore we must disassemble following from the MK2/S:
⬢All motors (Y-axis, X-axis, Z-axis and Extruder) and trapezoidal nuts
⬢Motor pulleys (2x)
⬢623h bearing housing (2x)
⬢LCD screen, front cover and knob (supports will be different)
