  • Hello, guys. I happened to use the exact same stepper driver. It is powerful without any doubt, however, I found there existed some problems. I can control my stepper with my 51-MCU, but the maximum speed of the stepper 4.5r/s, that is, 900 steps/s or 270r/min, it is too slowly! I just have no idea how to fix it. And, I found the current is just 300mA at most. Strange. Any one can help me? Thanks in advance.

No public wish lists :(
