    I am in the process of converting from an Arduino controller with Stepper Online motors and external drivers to an X32 controller. I am having a lot of issues, but the current one is my motor driving the X axis will run for a random period of time and then stop turning and whine. It kind of acts like it doesn't have enough power to drive it. I am wondering if my motor is too much for the X32 internal driver. I've tried adjusting the current. Thoughts? Link below.

    Check that your motors electrical specs are similar to ours. 3V Coils, 1-2mH Inductance, <3.2A Max current.

    Whining noise is stalling, can address by dialing down Acceleration and Max rate in Grbl Settings

    I don't see the Volts per coil, but:
    4.2 A max current
    3.2 mH Inductance
    So my guess is the volts are too high too.

    So ours with lower inductance, will have higher top speed before stalling. Higher inductance = higher back-EMF, which exhibits a self-braking characteristic the faster the motor goes.

    Voltage rating - lower = faster acceleration

    Our High torque motor is a little slower than NEMA 23 Stepper Motor - our standard motor for our machines. Balance of speed vs power is up to your use case mainly
    Before going on a motor replacement, just tune first though:

    Grbl v1.1 Configuration and Grbl v1.1 Configuration
