      @hussainsail2002 Yes, i have swapped for 0.9 degree stepper motors and the problem is gone to a minimum. The ripples do not feel physically anymore

        I think this is somehow a weakness of the cartesian / 'i3' design. I go back to fighting it now and then, but don't see it on my delta or the one print I've done on my new-to-me corexy.

          @robm It must be. On other designs both x and y are more or less weight balanced and the print stays put.

            @agniusm Thanks I had the rippling on my MKS board , when I changed to duet it got eliminated.

            Any Idea what the reason behind this could be ?

              @agniusm Did the spacing change (assuming you can still see a lesser effect)?

                @nophead Its very hard to see, basically impossible. i will see if i have old sample to get you photo comparison
                P.S. Black with 1.8 motor, clear with 0.9 motor if you can spot the difference

                  Black shiny plastic is always the worst for showing defects in my experience, so comparing it with clear is always going to be difficult and anything clear or white is hard to photograph with detail.

                    @nophead yes bit the ripples were visible on clear too. Now they are gone.
