Introduction v
Introduction
Thank you for purchasing one of our amazing Makerfarm 3D printers. Before jumping
into printing you need to follow a few steps.
First you need to follow this guide step by step. Printing out a hard copy is highly
recommended. This will ease the build process and make things go as smoothly as possible.
Second a basic knowledge of hand tools and simple electrical wiring is required. If you
have never built anything on this scale don't worry as the instructions go through every little
step.
Third you need to have lots of patients. This kit will take a minimum of 8 hours to build
if everything goes smoothly. If you run into any problems you can always call our help line Mon-
Fri 8-5.
If you just follow these simple steps then in no time you will have an outstanding 3D
printer to create anything that comes to mind!
