IN THIS CHAPTER
Getting an overview of RepRap electronics
Looking at modular components, sensors, and motors
Examining RepRap wiring and connections
Reviewing firmware configuration
The electronics and firmware running a RepRap 3D printer represent thousands of man-hours of development and refinement to achieve an operational machine. In this chapter, we explore common RepRap electronics, look at the firmware used to drive the electronics, and explain how everything comes together to make a 3D printer. We also look at wiring, upgrades, and optional parts, along with the sensors and motors that provide the all-important mechanical movement.
Reliable and stable electronics — that’s what you need for a 3D printer. Electronics are the very heart of the complex mechanical operation and must be dependable throughout the many hours they have to work while you’re waiting for a complex print to finish.
RepRap electronics were born from the open-source Arduino project. Arduino is an industry-standard embedded ...
