    Hello, today I will probably break the record for questions on the forum, but I would like to ask one more thing that is important to me. I managed to successfully configure SMC3 Utils and SimTools, but I have a problem with uncontrolled rotation of one of the motors in the opposite direction. By default, the range of motion should be a few degrees from the "0" position, but in my case it rarely happens that the one motor starts turning in the opposite direction by 360 degrees. I don't know whether it will make one turn or several in the opposite direction, because the arm has an aluminum profile in its path that stops the motor. After switching on the power (Arduino and motors) again, the Hall sensor reads the positions correctly and the motor is ready to work again. Today it happened to me 3 times during the day. I use 250W 75 rpm motors, Hall sensors and IBT2.

    Can you please post pictures of the SMC3 settings for the problem motor running the Sine test.

    Here is a screenshot, the settings are the same in the second motor, but such things do not occur there

    Thanks for the reply, actually when I went to SimTools I forgot there was anything else in the manual. Tomorrow I will set these parameters and test further. I hope this helps
