Welcome to the assembly instructions for the MillRight CNC Model M3 kit. Assembly will
take between eight hours and a weekend depending on your experience, tools, and work pace.
Don’t get in a rush. Although you are probably eager to get your machine toget
her, it will pay
off to take your time and have fun along the way. We encourage you to read the instructions all
the way through first. This will help you understand how the step you are working on ties into
the next. After that, follow these instructions step by step. If you get stuck or just have general
feedback, please email us at [email protected]. We strive to email back within a day.
