This board is made for microstepping for stepper motors. It can attach directly to the controller's 96-pin DIN connector, with no cables required, and Galil's SDM-20620 works well with 2-axis applications. The SDM-20640 measures 6.92 × 5.10 inches. It includes four microstepping drives on one board, each capable of driving a two-phase bipolar stepper motor running at 18V dc to 60V dc at up to 3.5 Amps. They also put out 64 microsteps per full step or 256 steps per full cycle, for 12,800 steps per revolution for a standard 200-step motor, with a maximum step rate generated by the controller of 3 million microsteps/second.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
