Great idea on having a fine print resolution to fix that issue. What I have opted to do lately is to print the top part separately with a thin base, and do the larger base with lower infill percentage. Later I glue these two with gorilla glueYeah the first few versions out was clear from the preview that it wouldn't come out right at all, there were gaps and weird uneven bits... what I've done so far to try to help it are to set the print resolution quite fine, adjust the thin walls setting, and get it to 'iron' the top surface of the model after printing - it's improved the preview version at least!
I've been having lots of fun looking at the planned print path to understand how it will move, but I'm sure when I actually start printing things there'll be a massive learning curve. Which is great, that's what keeps me going
