Hi thanx again. No, coasting was not enabled. So, my conclusion is that this has to do with extruder mechanics. For example, the extruder could lack sufficient pressure to push out the plastic in time when it starts a line or there is some unwanted retraction (by the plastic itself and not the extruder) when traveling. Heating more (e.g. 230 for PLA) should help a bit, I have "heard" some folks printing PLA at 240^C when printing with large nozzles and will try that too. I don't want to add more extrusion since it leads to messy knobs. Other than printing with smaller layers (e.g. 0.56mm for a 0.7mm nozzle) I don't have a solution, yet 🙂

Hi, thanx. I think it's off (unless I checked it by mistake) ! I will see on Monday, since the printer is at work. - greetings !

Hi, thanx much for the help, but this is not my problem (I should have explained better !). The walls do join, but the ends of the walls do not. I attach a new picture that shows the problem better. Actually (after posting) I now have the hypothesis that the pressure in the nozzle may not be enough and that there is a short lapse before the printer starts extruding after a jump.

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.
