Managing motors with dual L298N

I’ve got problem. Every motor test fails. They wont even move(or I’m blind).
Im using A58SW-555B motors 1:290 27RPM witch buildin encoders.

I will try again tomorrow because today, only think ive done is to run GC on old laptop

I run GC on linux witch succes, but still every motor test fails.
I created test programs to set mill plate in middle of board using arduino, so H bridges works fine and moves plate w/o problem.
My bet is that encoder is connected badly. I rotated encoder witch finger and get message that Error Message that Sled is not Keeping Up
Help me understand that.
