I'm using Cura. Only doing the basics. Trying my hand at Fusion 360 for bespoke designs (only done the one so far). I've found it's a steep learning curve on the software. Thank goodness for Thingiverse etc.
That turbine looks very good. Also very ambitious. Has the printer stood up to it all? I had a filament jam in the feed mechanism which meant I had to disassemble the feeder head. Learning a lot.
Looking at doing a skeleton clock eventually. Only 50 pieces!!
