I have a 3D Solex print head, I have changed the nozzle size to 0.25. the print screen still shows it as 0.40. How can I change the nozzle size for print?

    You simply change "line width" setting in Cura.  I recommend starting with 0.25mm line width.  In general you can do 75% to 150% of any nozzle size so 0.2mm to 0.35 should be a reasonable range.  But stick to 0.25 if that is a reasonable accuracy for you.

     

    Take note there are many line widths.  Make sure you aware of them all (just type "line" in the settings search box and relevant settings will suddenly appear even if they aren't normally visible).  I recommend infill line widths are the same.  Changing line widths mid print is "bad" because you will then get a brief overextrusion or underextrusion until the pressure in the nozzle equalizes.

    Depending on how often you change the nozzle sizes (I’d find it a little annoying to constantly do this), you can also reprogram the core to a specific one. There is a nice instruction here (in general a very informative thread 😊
