I'm rather happy with Cura, but recently I tried to replicate this lovely pattern on the top/bottom layer of the print (Hilbert Curve), sadly it is not available in Cura 5.1.0:
It is available in PrusaSlicer 2.5.0 though: Print Settings → Infill → Bottom fill pattern → Hilbert Curve
The other reason is: I just like trying and learning new things 🙂
