I was printing a holder for a CC3D case and i noticed that the lines dont connect properly

Im using cura 12,08 to slince and a ulticontroller to send the gcode.

Settings are as follows:

ulticontroller:

failsafe settings

cura:

wall thick: 0.8, botton/top thick 0.6

speed/temp: 80/200

diameter:2.85

in this picture you see the middle section almost skipping every second line, i measured the lines at 0.4 mm

In this picture you see a gap between a mounting hole and the outside wall, this dosent get filled inn.

    i turned the wall thickness down a notch and it started to fill it right in.

    is cura not responding properly to edge and hole close?

    i see when it layers it down, there is supposedly going to be 2 lines, but it draws only one.

    It's the "thin wall problem". Cura (skeinforge) knows that the nozzle size is 0.4mm and if there's a wall that is say 1mm thick it will put one line on each side leaving a 0.2mm gap inbetween because it thinks it can't fill that space. Some other slicers work around this and doesn't have that problem.

    As for the other problem. Maybe your filament is slipping so that not enough material is being put down? Pull out a bit of filament and check if it has nice "teeth marks" in it and doesn't look chewed up.

    im working on a bertho extruder upgrade right now, as i have problems retracting and it tends to grind.

    the filamet have nice tooth marks on it, looks abit chewed up.

    But im unsure how deep and deformative it should be.
