It´s in the "machine" settings where you tell Cura the size of your
actual print area ( not the size of the heated bed )
You can see it in Cura, when a part doesn´t fit in the defined print area, the color changes yellow to Grey. You can manually move/flip/scale the part until it fits.
When you home the printer and the nozzle is not at the corner of the bed ( 5-10mm to the center is OK ) then you can change the position of the endstops or change the values for home position in Marlin
Instead of
?-MIN-POS "0" you can set a positive or negative value, depending on the distance of the nozzle to the desired home position. ( Same goes to MAX_POS of course )
// Travel limits after homing
#define X_MAX_POS 200
#define X_MIN_POS 0
#define Y_MAX_POS 185
#define Y_MIN_POS 0
#define Z_MAX_POS 150
#define Z_MIN_POS 0
