Walls not solid, lots of small dots/dashes


Recommended Posts

Posted · Walls not solid, lots of small dots/dashes

Hi - I think this has been brought up in the past, but flagging it again anyway. Trying to print a 1.2mm wall with a 0.4mm nozzle, gives two solid outer walls, but the inner wall is a series of dots and dashes. Really slows the printer down, not ideal! There are settings that I think are supposed to fix this, but I cannot get them to work. On wide flat 1.2mm walls, it generally works but sometimes just leaves a gap in between. I have to alter my models to 1.21mm to get the walls a solid 3 layers, attached pics show this difference.

So, requesting a fix for this! Or if there is something obvious I have missed, let me know, but I am pretty sure I've tried everything relevant.

    Try setting "minimum wall flow" to 50.  I don't know much about this issue - you could mess a little bit with line width (set it to 0.35mm instead of 0.4).  Also maybe play with "print thin walls".  Maybe?


    @burtoogle is the expert on this issue and I forget what he said exactly but I think you just need the "minimum wall flow" thing.  Maybe.
