It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

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 printers, ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

The 3000's small size (63.6 26.4 mm) makes it a candidate for robots and other industrial control equipment. The controllers can drive unipolar stepper motors in full two-phase, full one-phase, and ...

Stepper motors are impressive little engines that may not be getting the credit they deserve, as they are a relatively important part of our electronic lives. Printers and CNC machines are ...

The project illustrates the control of two unipolar stepper motors using this circuit in full step mode through the RS232 serial port of the PC. The signals from the serial port of the PC is being ...

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 ...
