Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D ...

Even veteran engineers often suffer from a lot of misconceptions about stepper motors and how to drive them. This article will focus on clearing up just a few of these misunderstandings so that ...

There’s an older article about using an FPGA to control a CNC machine that has a ... I feel it’s more practical to let a single microcontroller do the stepper/closed loop control for each motor.

Stepper motors are often used in demanding applications, such as this packaging machine. Here’s a look at those advances, and an overview of the other two leading motion-control devices for ...

From the CNC mechanics point of view: grblHAL-based hardware can output many more step-and-direction-pulses per second than grbl-on-AVR, to more than three stepper motors. grblHAL is in two parts: an ...
