I have a prusa i3 pro w, how do i set the right bed size in ultimaker cura 4.7.1?

[DaekDragon 0]

I recently bought a prusa i3 pro w, im using it just fine selecting the "prusa" printer in the cura settings.

Just one little thing, my bed size is so wrong.

 

I find myself forced to print in a smaller size because of this. I'm new to the 3d printing world and I struggled with other softwares, ultimaker cura 4.7.1 is perfect for my printer and what I want to print, the problem with the bed size is the only thing stopping me from going big.

 

Thanks in advance for you help 😞

You should be able to configure the bed size under Settings - Printers and then click the button Machine settings.
