Underextrusion problem in certain areas of a wall

[Sebastian1986 0]

Hi,

attached a picture of a printed wall (5 mm, 7% infill, wall thickness 0.4mm, speed 30mm/s). There you can see some spots with underextrusion?! I expect it depends on the way of the extruder - that would explain why it always ends at the same spot. Did you also have this problem? How can i fix it? I also think the stl quality has an influence.

Thanks a lot for your help!

5mm (whats 5mm?) 0.4 wall is far too thin for me even though you can do it, but with more practice, and 7% infil is pointless, dont go below 18%. Speed is ok and the slowest i will go to get a good quality print as long as its not tiny, in which case ill print more so that the nozzle doenst hang about on one for too long.

those gaps mean underextrusion normally, not sure what your layer height is though.
