    Strings between parts.

    Hey guys,

    As the title already kinda explains i wanted to talk about those strings when the hotend goes from one side, To another side where it shouldnt print.
    But like many know most of the time you will get a nice string when it crosses between these two sides,

    Kinda wanted to ask how you guys made it better?

    I start to think that this could just be my plastic that isnt that great as quality goes.

    You need to fix your retraction settings, for mine i have it set at 2mm with a retraction speed of 35mm/s...seems to work fine for me.(im using a J-Head) Are you using Slic3r?

    Yep it's a retraction issue. Personally I don't use retraction because I find Cura takes care of a lot of the stringing and they're just like fine hairs that fall right off. Some filament can be very sticky so stringing might be worse in those cases.

    Try speeding it up until it stops stringing.

    Ah, I always made it slower and made the length of the restract longer, Well i will try that,
    Will put here later on perhaps some photos and such how it became better or worse, If i have some time.

    I find that the temperature can also make a good difference, if it's too hot, it will string more. Have you played with the temperature and tried lowering it a little?

    Anyone have tryed 15mm/s retraction on there makerfarm?
    Mine is 4.5mm far, and it makes a very crunchy sound, If this is unusual i will make a sound record of it.

    Gonna lower it down a little.


    Expected this alot worse,

    I did it to 13mm/s and seems better now,

    I've have some PLA that works great at 190 and others at 209, depends on manufacturer I guess.
