Hi, I am printing 0.7mm and 0.6mm layers with a 0.7mm nozzle. Some outer wall ends do not join well, typically small circles that you would find underneath duplo compatible pieces. Right now, I got retraction = off, skin overlap percentage = 20 (0.14mm) and extrusion = 100%. The walls themselves and walls with infill context nicely and I print rather slowly, i.e. about 33 mm/s.
Any ideas what I should do, e.g. define negative extrusion ? I am aware that this is a problem influenced by how much (little) plastic the printer can push through and I am just asking if someone has a good "trick" for my problem. Also, the previews look just fine, lines are joined.
Cura version 4.8.0 on Ubuntu 18, Felix Pro 2 printer
PS: In case you wonder why I print Lego and Duplo compatible pieces so coarsely: I just want to create lots of pieces in reasonable time and the ones I do fit nicely and are functional.
