Introduction

The Ultralight N17 is a RepRapFirmware and Klipper compatible expansion board, developed in collaboration with Millennium Machines.

It uses CAN(-FD) to communicate with RepRapFirmware or Klipper (or anything else for that matter), allowing you to control a single bipolar stepper motor. It exposes one input port for an endstop (3 pin, PH 2.0) and one output port for any auxiliary device, e.g. a fan (2 pin, PH 2.0).

This page covers the r1.5 version of the board.

2. Configure Jumpers - Set up VIO, CAN mode, and termination
3. Mount to Motor - Install on your NEMA17 motor

• Everyone on the Millennium Machines team for their hard work, and encouragement to take this on myself.
• Jay_s_uk and Gloomyandy from TeamGloomy for their technical assistance and ideas.
• DesktopMachineShop Dave for supplying me with endmills that never get used as my Milo is mostly a software development platform at this point!
• The Duet3D team who without which, we would not be running RepRapFirmware on CNC machines.
• Allen from West3D for the amazing photos of the board and printed mounts, and for putting it through its paces.
