The VME58 multi-axis programmable motion-control boards combine both servo and stepper motor control on a single board of four to eight axes with a VME bus interface. The family of single-board motion controllers provide closed loop for both servos and stepper as well as open loop for steppers. Features include smooth, high resolution; high speed; and minimal torque ripple. A PID filter, incorporating the encoder feedback, is provided in real time for the servo control and position error correction. The parameters for the VME58 PID filter are user-adjustable for tuning to the optimum system stability.

By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
