Selling my RepRapPro Duet 3D printer controller along with Duet Shield and 5V regulator board.
This is one of the best 3D printer controllers you can buy as it has a 32-bit processor for super smooth motion, and ethernet capabilities.
Taken off of my Ormerod 1. This is a duet board from RepRapPro when they were still in business (not a Chinese clone).
The Duet Shield provides an additional 2 stepper drivers for a total of 6 (XYZ E0, E1, E2) and so would be great for a 3-extruder setup such as the Diamond hotend.
