and

Yes.

when i try to calibrate the joint 2 i notice that the screen is different from the other Joints
is this normal?

If you are sharing the PID values between joints 1 and 2, then yes.

when i try to enable the linux cnc f2 i have a Joint2 error
in Joint 1 and Joint 2 i have identical bru 200 motors and drivers with exactly the same P>I>D settings
what could cause this??

Do both motors need to turn in the same direction? Most gantries need the motors to turn in opposite directions.

You may need to reverse Y2. (make the encoder scales and analogout-scale both the negative of their current values).
