So what’s the trick to running a whopping seventeen individual stepper motors directly from the digital pins of an Arduino Mega?

Rather than write a bunch of stepper motor code himself, he installed and ran a four-axis fork of grbl on the Arduino, turning it into a stepper motor controller.

Step Two: Copy, Paste, and Run the Code in Arduino Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch.

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible.
