The controller uses a Raspberry Pi as the brains of the device, but there aren’t too many options out there for stepper motor control in Pi land. There are, however, dozens of CNC shields or the ...

If you're looking for clever ways to repurpose any of the old CD or DVD players that might be scattered around your house, we ...

For Part 1 of the How-To, we'll go over all the major components of the project and get started with the controller. The major components of the DIY CNC machine: Stepper motors drive positioning screw ...

The EMMS-ST two-phase hybrid stepper motor offers high torque with options for an integrated brake and incremental encoder feedback. Features include a holding torque from 0.5Nm to 9.3Nm, external ...

When you write software to control a stepper motor, you must first know how many pulses the motor needs to turn a full rotation. In addition, you need the rotational speed expected by the device ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1 ). However, this idea integrates not only the driver, but also a simple one-axis ...

By improving stepper-motor controllers in two key areas—adjustment of the motor-driving current and the method of step-pulse generation—existing mechanisms can deliver that desired BLDC-like ...
