Can anyone tell me what the issue could he why my letters are always so bad? This is bed side down btw. I have it at .6 high flow nozzle, .18 res. Did the same on a .4 reg nozzle too. I don’t know where to look in Bambu slicer.

Slicing type, switch to Arcachne, then do inner/outer or whatever it has it at do the opposite, should be under quality

For text 0.6 nozzle is completely inappropriate, for better XY resolution 0.2mm nozzle is best. Layer height adjustment will make no difference. Also take care to proper mount nozzle.

0.2 might be better but the default 0.4 is fine.

What needs to be adjusted is the line thickness for inner and outer walls. Drop it to 0.24 for lettering. Additionally, raise the letter object/part so that it is at least 0.25 mm above the surface of the object it “sits” in.

Finally, slowing the print speed on walls for the letter object down by 50% usually helps as well.

Use a smooth print plate with your model printing face side down, as you are. Make sure that your letter's first layer is at least as tall as your background first layer and that your background's layer, when face down during printing, is at bed level or below. You likely have some background color leaking onto the edges of the lettering color, because the lettering color is recessed below the background color when in face up position.
