  • What, if any, might be opportunities to volunteer?

  • Is there any way that changing the motor supply voltage while the motor is running would spike unexpected loads into the driver and blow the chip? I have a benchtop power supply and I was trying to get the motor to spin faster by increasing the voltage (from 25V –> ~30V) and it quickly overheated and went into thermal shutdown. Once it cooled, the light came back on but resistance tests showed a blown driver chip.

    I was using SF’s stepper ROB-10846

  • Is it possible to use this device with a Arduino Uno? Is it necessary to use a logic level converter?
