This article includes everything you need to know about controlling a stepper motor with the A4988 stepper motor driver and Arduino. I have included a wiring diagram, a tutorial on how to set the current limit and many example codes. The A4988 stepper motor driver carrier is a breakout board for Allegro’s easy-to-use A4988 microstepping bipolar stepper motor driver and is a drop-in replacement for the A4983 stepper motor driver carrier. The driver features adjustable current limiting, overcurrent protection, and five different microstep resolutions.

When changing the extruder motor to a compact but powerful motor (recommended for the Titan and Titan Aero) or Slimline motor (still useable but may require slower printing speeds) you will most likely require a slight adjustment to the stepper driver to ensure that you are not over or under powering the motor. A4988 stepper driver board. I am pretty confident that the Allegro A4988 is an utterly tested and proven solution to drive stepper motors in RepRap 3D printers, and this fact should not be overlooked. As long as the following three conditions are met, these Made in China Allegro A4988 stepper driver boards seem to be bullet-proof workhorses: Overview. This CNC shield software is designed to control a CNC or a 3D printer. It comes with 4 sockets A4988 stepper driver. This board has Arduino pin connections and pins for engine and other peripherals.
