    Can you please post a picture of your SMC3 setting running the Sine test.

    hello thank you for your help here are the photos I put two more photos to see the value output of the motors, the values which are displayed in SMC 3 they were put automatically when I turned on the application, smc3 thank you for your help.

    Can you please verify the comm port has not changed in Device Manager.

    Given you had this working have you done anything that may have damaged the hardware?

    the gate is good. I noticed something in the dips 1 2 3 4 5 6.1 and 2 off the other numbers in ON there is no value coming out but when I put all the dips in ON the motors start to turn. Thank you.

    Hello friends, I managed to recover some of the settings but they are still strange. Does anyone have any ideas? Thanks for your help.

    Try setting PWMmax and PWMrev to 150 and then run the Sine test.

    Hello, thank you for the answer, but it's even worse if I go up to 150. I'm going to take the engine apart, I find that there's a lot of play inside. I'll keep you posted on the rest, thank you☺️

    Following the SMC3 setup instruction at what PWMmax value does the motors start to move:
    1. Disconnect the motor power supply
    2. Make sure Simtools is not running – we’re not ready for that yet!
    3. Wire up the Arduino (with SMC3 installed) to your H-Bridges and connect to your computer via USB
    4. 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)
    5. Set the Kp, Ki, Kd, PWMmin, PWMmax, PWMrev to 0 for ALL motors (This will make sure the motors don’t move)
    6. 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)
    7. Turn on the power to your motors – nothing should move at this stage!
    8. Set Kp to about 400
    9. 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.
    10. Do the above for each motor

    I managed to move the two engines I am settled with Simtools and the LFS I will keep you posted afterwards thank you very much.☺️☺️
