3D Printer M508 Quick Start Guide
Foreword
Thanks in advance for choosing our M508 3D Printer! With the Quick Use Manual (hereinafter as “Manual”)
guide, you could enjoy accomplishing the assembly, Test and Printing step by step. Meanwhile, you will also
learn the structure principle and its special FDM printing technology deeply, and then you will get great
progress on not only the theoretical knowledge but also the manipulative ability.
To give play to the bigger effect of the printer and ensure the worry-free buying, smooth and enjoyable
using, we spare no effect to consider the question and difficulty you will meet with from when you order the
printer and make detailed videos and pictures to show the exact settle way. We write this “Manual” elaborately
in great detail and we will always accompany with your using 3D printer. The kits would come to you with
