Paso 1 Introducción
⬢This guide will take you throught the replacement of the silver PSU (Power Supply Unit) with the black PSU on your Original Prusa printer.
The following instructions are provided as an extension to preparation for the MK3.9 upgrade and MK4 upgrade.
Do not start disassembling anything on the printer! Wait for instructions.
⬢Before you start disassembling the printer, make sure you have received the black PSU 24V 240W from Prusa Research.
Keep the PSU aside, we will need it later on.
