  • Got this board for the holidays, was testing this board out with moving a stepper, and worked well. Then I was getting higher speed by using acceleration based control. this worked well, got delay down to 600uS no problem, then reduced the delay to 400uS, ran and braked with Gcode, it spun up, and as soon as the brake was applied, a large spark sound was made, and a hole was blown into the IC chip, guess the fly-back voltage was too high. And not only did this fry the BED, it also fried my Teensy3.6.... Stepper was the 125oz. in. sold by Sparkfun.
