Extruder limiting current

Hi everybody!

In these last days I am struggling with the limiting currents of the extruder I am trying to use. 

I am new to the 3D printers but I have tried to modify the firmware to decrease the current levels and apparently it doesn't feel it. 

I have a limit at 250mA.

On raws from 287 to 290 I have changed from:
#define TMC2130_CURRENTS_H {16, 20, 35, 10}  // default holding currents for all axes
#define TMC2130_CURRENTS_FARM 36             // E 805 mA peak for ECool/farm mode
#define TMC2130_CURRENTS_R {16, 20, 35, 10}  // default running currents for all axes 0-63 = 0A-0.96A linear
#define TMC2130_CURRENTS_R_HOME {8, 10, 20, 10}  // homing running currents for all axes

to: 
#define TMC2130_CURRENTS_H {5, 6, 11, 3}  // default holding currents for all axes
#define TMC2130_CURRENTS_FARM 11             // E 805 mA peak for ECool/farm mode
#define TMC2130_CURRENTS_R {5, 6, 11, 3}  // default running currents for all axes 0-63 = 0A-0.96A linear
#define TMC2130_CURRENTS_R_HOME {2, 3, 6, 3}  // homing running currents for all axes

Nothing changed. Do you know how I could do?

Thank you!
