where does this marks came from?

Hi,

I´m wondering why this piece have that kind of marks only at the bottom, where the Y axis went all the way for the 160mm total print dimension. As soon as the Y axis start to print at another "dimension", after that big fillet in the Z direction, the marks (bands?) were gonne (well, not totally, we can see them also in 2 sections above)..
Is that something about how the steepers works, and drivers, and that kind of stuff?

What Brand and model of printer are you using?

and... Yes, the "zebra" pattern is probably from missed steps on the extruder stepper.


I have a Wanhao i3 Plus and had these for a long time.

I experimented and eliminated them by adding what is called a "smoother" Now they have 4 diode and 8 diode smoothers. I and most others found that the 8 diode smoother works the best, at least with the stepper drivers I have in the i3 plus.

Don´t know what kind of drivers it have, but I´ll give a look into that smoothiers thing..
Thanks for the reply!
