The Stepstick and Pololu motor drivers are the heart of just about every Reprap electronics board, but they can go bad. The usual way of testing these things is to rig up a microcontroller on a ...

A new series of microstepping motor driver integrated circuits with an integrated step and direction translator interface has been developed specifically by to drive bipolar stepper motors. These new ...

The DRV8846 is a 1.4 A bipolar stepper motor driver with on-chip microstepping indexer (Step/Dir Ctrl). This device is intended for cameras, printers, projectors, and other automated equipment ...

The R525 microstepping step-motor driver measures just over 3.3 inches long and 1.3 inches high, making it easy to accommodate in most systems. It’s capable of outputting a 5-A peak current and ...

[TBJ] is building what he calls a junkbox 3D printer. You can probably guess that he’s trying to salvage most of the parts for the device, and after pulling a stepper motor from an old printer he was ...
