PSMD (Pololu Stepper Motor Driver) Triple Axis Driver

The PSMD Triple Axis Drive prototype (center), with an Arduino Mega (top-left), a Gen4 Stepper Driver (Top-Right), and an earlier PSMD triple-axis board (bottom-right) for scale.

A drop-in replacement for the MakerBot stepper drivers that contains all three axes on one board. This is a carrier board for three Pololu A4983 stepper drivers.


This board and the drivers make your stepper motors run at eight times higher resolution (1/16th steps instead of 1/2 steps), making it run smoother and way quieter.


Price: $45/each
