Benchy with gaps in outlines

[Derdoo]

Hi Makers,

Sorry for my noob request, but I don´t have any idea how to fix that.

I'm used a modded Anet A8 and Simplify3d to print this Benchy in PLA with 60mm/s.

But there are always these "Gaps" on the front and on the sides. I tried different speeds, temperatures and filament.

These "Gaps" are in every single print on the exact same place, so I think it can only be a problem with the gcode.

Can someone tell me how this is called, that I can google it, or give me a hint, whats wrong?

Rotating the model dosn't help either.

Thanks for your support.

That probably just means that you need to adjust your retraction settings. Perhaps you are using too much coasting, or too big of a negative extra restart distance.

Hi Brian,

thanks for you feedback.

I think I don't use coasting or negative extra restart distance.

I did some test prints with a lower retration distance, now i'm at 1,5mm but there is no change at all.

Should I still turn down the retraction distance? The Anet works with the stock direct extruder.

Thanks for your support and greetings from Germany

So you said they are actual gaps or holes right? If so, you could try actually increasing the extra restart distance. For example, set it to +0.2mm and see if that makes a difference. If not, try 0.4, 0.6, etc until the holes are filled in.
