If that quality is alright, I recommend starting with 0.4mm nozzle, as it is a good balance between speed and detail (and I believe that it’s by far the most common diameter too).

And if you need more detail you can replace the nozzle with a smaller one later - It’s a pretty easy operation.

I don’t remember what your original question was, but I can recommend the Core One as a pretty good beginner friendly printer. It’s pretty Open in that you can use any slicer you want, (I use PrusaSlicer… it does what I need) and Prusa isn’t taking the walled garden approach that Bamboo is currently going for.

I highly recommend getting the kit over the already assembled one because:

• It teaches you how everything fits together, making maintenance easier.
• It’s fun. The assembly instructions are really good.
