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 ...

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 ...

Never one to pass up the recycle pile at work, [Scott] usually doesn’t find much. A few old hard drives, maybe a ancient laptop every once in a while, but on very rare occasions he finds something ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

If you are building a project that needs to control stepper motors wirelessly you might be interested in a new piece of hardware created by the team at Good Robotics which takes the form of the aptly ...

The Five-Axis Integrated Stepper Module (FAISM) controls up to five stepper motors and includes a stepper translator so output connects directly to the motor. Five channels of SSI encoder feedback are ...

The USB's many advantages have led designers to come up with a wide range of applications for the bus. For example, the figure shows a USB-based controller for four stepper motors built using ...
