When I test encoders by powering the motors off, encoders work fine. But, when I power the motors on, at the test, J4, J5 and J6 start counting by itself automatically. (See video.)

Why? 🤔

Aditionally, when I test jogging j4, j5 and J6 motors with encoders, I get "Collision or Motor Error". (No problem without encoders)

What problems might be cause this?

Note: I use AR4 Robot Complete Electric Package and Teensy 4.1 AR4 HMI interface 3.0 and 3.0 sketch
