Recently I got a cube3 printer and I printed already some things with it. However sometimes the prints aren't as good as I want them. The printer leaves these dots on my print and it also doesn't fill it entirely. I have a picture attached that shows the 'failed' print.
Welcome to the forum Dreez. For what it is worth, that is a pretty good result.
The shortcoming are from the slicer and the bowden tube style of printer.
These printers and their default software do show their age.
People have pushed these printers beyond their capability yet universal slicers hasn't been cracked yet.
