To carry out the modernization, it is necessary to print several elements yourself.

Self-assembly kit

The kit is delivered as a self-assembly kit and requires the user to complete a series of steps according to the instructions. This process involves removing some of the printer's existing components and installing new components such as the motherboard, screen, and housing.

Printing the elements of the set

To make changes to the 3D printer, you must print some parts yourself that are not listed in the kit contents. Therefore, the set includes a filament with which the user will be able to properly print the parts necessary to carry out the modernization.

Detailed assembly instructions are included in the kit or on the manufacturer's website.

Before placing an order - check

Before you upgrade your Prusa i3 MK3/S/+ printer to MK3.9 with an available kit, it is important to check two key items to ensure your printer is compatible with the kit:

Power supply type (PSU)
:

  • If the printer has a black power supply unit (PSU) , it is fully compatible with the upgrade kit.
  • If you have a silver PSU, you will need to add a compatible wiring harness or replace it with a black PSU.

Heating table connector version :

  • If the heating table is screwed with 2+3 screws (power cable screwed), there is no compatibility problem.
  • If the heating table is attached with 2+1 screws (power cable soldered), the heating table will need to be replaced.

A detailed description of the compatibility of the printer with the set can be found on the manufacturer's website!
