Bad surfaces with Cura 3.4 on UM2 Ext+

Recommended Posts

Hello everyone, i'm having troubles printing compact and clean upper and lower surfaces with my UM2 Ext+ since i updated Cura from 3.3 to 3.4. It seems that the printed lines are not able to cover the whole surface, leaving little holes that pierce the print side to side. Also, in some cases, it seems that the lines are not very compact with each other and with the the outer walls too. I never had this kind of problem on the previous versions of Cura, i tried to disable "filter out tiny gaps" option, but nothing changed. Is there some else that i should try to change to solve this problem and improve my printings? Thanks.

I used default settings (extra fine mode, 0.4mm nozzle) since the first print with Cura 3.4 and got bad results, then just turned off the "filter out tiny gaps" option and that covered the little holes in the preview (i forgot to take a screenshot), but as you can see in the printed part pictures the result is still bad. As i said, i already printed that part before on previous Cura versions with the same default settings and never got this kind of problem. I updated the firmware of my printer by the way, i use to do that any time a new Cura version get released just to be sure.

They all keep presenting tiny gaps, no matter what... I don't understand why all the default printing modes, even the extra fine one that should be perfect for small objects like that, got so messy since Cura 3.4. Any idea?
