There is no change in values.

are you connected to the right com port for the teensy and arduino boards?

Yes, I checked the connections. As I wrote, when I click on the (+) and (-) buttons, the joints move, only the values do not change.

Is it your suggestion that I disassemble and reassemble all the locks?

I SOLVED IT:

when using version 2.2, he read the values.the (+) and (-) minus buttons show the value.It's not just the j6 engine going counterclockwise. When you click on J6 + and minus, it moves clockwise.
