Easy solution.
Split the object in 2. One the base the other the texts. Merge on cura, select the text object and assign a lower nozzle size to make the extrusion on that area finner. Play until it fits and also, check the gcode view before printing to see if there’s gaps.
This is already what I do. I have the base printed with a .4 and at a pretty fast speed. The text is done with the .25 with the settings stated in the first post. As you know this saves a huge amout of time with printing. Thanks for your help
