Prusa MMU3 for MK4 - Complete Assembly and 3D Print
Описание
The Prusa MMU3 for the MK4 3D Printer finally arrived April 2024 and here is my step by step assembly guide with many tips and tricks where I show how to assemble the MMU3 (Idler, Selector, Pully Body, Electronics), upgrade the MK4's Nextruder for the MMU3, and configure the software and firmware for both. I show the new Prusa Buffer and Spools, but then showcase my own custom Multicolor System, and finally print a test model to demonstrate.
