    Hello, sorry for my bad English but I will try to translate it in the best way. What happens is that with some friends we are making a 2DOF using Arduino UNO and 2 BTS7960 of 46A guided by the configuration of the SMC3 and Arduino forum. What happens is that we cannot get the SimTools to move the large motors (24V) that we are going to use in the simulator, that is, in the SMC3 we do get movement and we can calibrate the potentiometers, but when we go to try it with the SimTools we directly do not get any response or movement. On the other hand, when we test with small motors (2.5V or 5V), in both SMC3 and SimTools we can move both motors and get a correct response of data sent.

    Can you please post a picture of the SMC3 settings running the Sine test with the large motors.

    These are the images of both large motors running on the smc3

    It is not tracking well, try increasing PWMmax and PWMrev to 100, Kp may also need to be increased.

    With respect to SimTools try temporarily disabling antivirus and test SimTools in Output Testing to see if that is interfering with communications.
