<p>That's my first 3d printer. I'm using Repetier Host as the brand recomends, and set all the configuration as the recommended one. I decided to print one STL file but the result is not the best one.
That's what I was trying to print:
<a href="https://i.stack.imgur.com/f1V22.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/f1V22.jpg" alt="handle"></a>
and that's what I've got.
