Cura slice problem ~ ~

[sanbenny888]

The cura path odd, the starting point and end point of the path is not in the same position.

Hi ~ all
Is there anyone like me have this problem?
Is there any ways to improve it?

[magicmushroom666]

Check the actual paths in repetier see if they actually are meeting, i suspect its more of a retraction issue and the extrusion is delayed in starting.

Thank you!!
I check again ~
I hope hurry to solve those problems ~

You'll always see some seam, exactly how big and what it looks like depends a lot on the slicer.
Kisslicer does a sort of overlapping V at the beginning/end of a loop to try and hide it, and the wipe tends to leave a small excess there.
Slic3r and Cura just do what you'd expect, and usually you end up with a visible seam.
They all have options to randomize start positions, which IME looks worse.
Cura has the Joris option that works on a particular class of models if you are doing single wall prints.
The color of the material makes a big difference.

Hi~All
Kisslicer have been relatively good quality ~
However, there is still a gap surface.
In addition, aspects of the ear is still not satisfied.
The temperature of the hot end is too high?

The ears are almost certainly printing too hot/too fast/not enough cooling.

As I say you will get a seam, Kisslicer is at least predictable where it goes.
If you take a single wall test print and look at the top outer edge you can see why.
Imagine the pastic going down as a squashed cylinder with circular ends, as you complete the loop the circles have to overlap, and either you get too much or too little plastic both of which result in a seam.
Ensuring that the extrusion rate is perfect will minimize the seam.
Smaller nozzles have smaller extrusion widths and smaller circles and as a result smaller seams, but they are still there.

So if your willing to put a little bit of clean up work into it, would you say it's better to err on too much overlap since it's easier to remove plastic afterwords than to add it in.
