Review on Stepper Linear Slider Engraving Machine by Sean Garrison

I bought more than 1 slider stepper motor from different vendors. This one doesn't work. The engine began to warm up at 1 A. I heard a small high pitched beep but no movement at 9V. When I increased the voltage to 9.5 something shorted out. The electricity provider's switch has tripped. Exactly the same setup works for other steppers. Tb6600 was used in this experiment.
