    Hello good evening, I set up a simulator, but when I turn on the power supply the motors keep spinning continuously in the smc3, I can even adjust the hall sensors, but when I turn on the power supply the motors keep spinning and I can't get past that, can someone help me

    Can you please post details of all hardware used and pictures of your SMC3 settings.

    at the moment it is like this, but I started the test with almost everything reset, in all the tests the motors keep turning continuously

    What hardware is being used?

    Is the port correct?

    There should be a blue line in the middle of the SMC3 graph, but that does not seem apparent.

    Once the basics are sorted with respect to settings it is strongly recommend you follow the steps below if this is the first time you are using SMC3 with your simulator to reduce the risk of damaging anything: https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/

    Disconnect the motor power supply
    Make sure Simtools is not running – we’re not ready for that yet!
    Wire up the Arduino (with SMC3 installed) to your H-Bridges and connect to your computer via USB
    Run the Windows SMC3 Utility software and make sure it communicates with the Arduino (There is no need to set baud rates, they are not configurable)
    Set the Kp, Ki, Kd, PWMmin, PWMmax, PWMrev to 0 for ALL motors (This will make sure the motors don’t move)
    Set Clip to 255 (you need to do this first) and Limit to 255 (This will give you plenty of margin if something goes wrong while setting up)
    Turn on the power to your motors – nothing should move at this stage!
    Set Kp to about 400
    Now slowly, increase PWMmax… at some point the motor should start to move. When it does check the “Green” feedback line is moving toward the “Blue” target position.
    If it is then that motor and feedback is wired correctly - proceed to test other motors.
    If it is moving away turn off motor power immediately (or quickly reduce PWMmax again). In this case you need to either reverse the wires to the motor being tested –OR– reverse the +5V and GND wires to your feedback pot for the motor being tested (do not do both). Restart the test from the beginning.
    Do the above for each motor
