Hello.

I have a 6 year old Ultimaker2 and use Cura for a slicer. Over the years I have printed many things. My prints turn out 100% correct about 5% of the time and totally fail about 10% of the time. They are often satisfactory and usable, but often have partially missing lines from poor extrusion. There are many settings in Cura I do not fully understand, especially since there are frequent updates which add or remove features. All that being said, I give my understanding of how how use my printer and slicer 90%.

I am curious to learn about the success rate people have with their printers.

What I am considering a 100% successful print is one with no visible under extruded lines or strange blobs on any side, including the bottom. If it needs to be strong, then it is strong. Support structure marks are OK if they can be removed with almost no trace. The little strings that form with a hop from one location to another are OK.

Thanks
