Problems with current sensing

1

Hello all,
during my time now with SimpleFOC I had my system running quite well with closed loop angle control.
I just needed a bit more performance thats why i wanted to implement current sensing.
I tried adapting the code from https://community.simplefoc.com/t/problem-with-b-g431b-esc1-current-sensing/3417 but then the motor would not turn all the time and when it turned it had a big delay.
Then i tried the example code for the b_g431_esc that you can see below. In this code the setup for current sensing is already there. but as soon as I am uncommenting

motor.torque_controller = TorqueControlType::foc_current;

, the motor does not move at all. Is this just a thing of tuning the PID controllers or am I making a bigger mistake ?
