Wrenchy

Hi, Fairly new to 3D printing text on top of surfaces, I have an ender3 pro upgraded with dual z axis servo's, CR touch bed sensor and upgraded nozzle heating and sensing. I use Ultimaker Cura V 5.1.0 to slice as it is very easy to use and seems to produce better prints than than the creality slicer. Anyway the question I have is - How can I get rid of the annoying gaps between the walls of the text (as shown in picture) All/Any help or idea's would be gratefully received
