Need more information:
1. What is the construction of your X and Y axis motion systems, and what are their steps/mm at x16 microstepping?
2. Please supply the data for the X and Y stepper motors you are using.

But 2,2 kgf motors should't be capable of get higher feed rates or accel?Quote

The motor data I was after was the rated current, inductance and holding torque of the X and Y stepper motors, not the firmware settings. Anyway, if your steps/mm with full stepping is as high as 141, then almost certainly the problem is that you need very high motor RPM to achieve reasonable speeds, and you do not have enough motor drive voltage to overcome the back emf of the motors at those speeds.
If you have the motor specifications, this can be calculated. See [duet3d.com].
