¶ Introduction
It is strongly recommended to assemble the toolhead frames on a known flat surface (such as a solid table, work surface or similar). This will ensure that the toolheads are assembled squarely. A non-square toolhead can cause issues with print quality and performance.
Please note: Throughout this guide, the two toolheads will be referenced as follows:
- Left-Hand Toolhead - T0 or Toolhead 0
- Right-Hand Toolhead - T1 or Toolhead 1
¶ Step 1 - Tools for this guide
- The following tools are required for this guide:
- Allen key / hex wrenches in the following sizes: 1.5mm, 2mm, & 2.5mm
- Avoid using ball end hex wrenches where possible as they are more prone to damaging the heads of smaller screws
- Torx driver in the following size: T8

¶ Step 14 - T0 - Install the Rapido 2 hotend - Part 1
- V-Core 4.1 IDEX Toolhead 0 Assembly
- Phaetus Rapido 2 Plus UHF Hotend
