Part one of this series is here.
You know what a motor is. But you may now know what a stepper motor is. A stepper motor is a motor where an exact, precise, jolt of electricity will rotate the shaft one complete revolution. This is very useful for when you need to move something in a measured manner, like say, a printer. The Reprap will use several of these.
|The NEMA 14 stepper motor|
|I will be using Pololu A4983 stepper motor drivers.|
Now that you have background, here's what I worked on Saturday:
- Converted the loose wire ends on the motors to convenient plugs (x4 motors).
- Soldered the driver boards together (x4 drivers).
- Programmed the Arduino Mega to talk to the Reprap software.
|Lots of little bits to connect.|
