3D printing with RepRap Cookbook

By: Salinas

Overview of this book

A systematic guide consisting of over 100 recipes which focus on helping you understand the process of 3D printing using RepRap machines. The book aims at providing professionals with a series of working recipes to help make their fuzzy notions into real, saleable projects/objects using 3D printing technology. This book is for novice designers and artists who own a RepRap-based 3D printer, have fundamental knowledge of its working, and who desire to gain better mastery of the printing process. For the more experienced user, it will provide a handy visual resource, with side-by-side comparisons of the two most popular slicers, Skeinforge and Slic3r. A basic understanding of designing and modeling principles and elementary knowledge of digital modeling would be a plus.

Editing the firmware with the Arduino IDE

The configuration.h folder is usually the only file that most RepRap printers will need to adjust. This file contains the data that describes your particular electronics and stores the numerical data that calibrates your printer.

The line that is most commonly changed with a working unmodified 3D printer contains the X, Y, Z, and E steps per unit values. These values calibrate the movement of the printer and the amount of filament extruded.

In Sprinter, this can be easily found at the beginning of the configuration.h file. In Marlin, this is closer to the bottom-third of the file. Marlin can be seen open in the Arduino IDE in the following screenshot:

Editing the firmware with the Arduino IDE

Any data recorded with two forward slashes // is the data that is commented out and disabled. It can also precede comments for information purposes or records. When changing values in the firmware, it's a good idea to comment out your old values with the // for record-keeping in case you would like...
