      I have built a custom machine that had ripples on the surface using an MKS gen 1.4 board, Once I changed the board to Duet It was eliminated.

      Wondering what the reason could be ?

        They don't look eliminated to me...just looks like they are finer which could just be from the microstepping.

          @jamesm agree. Wonder what that's about. Op, have you carefully calibrated your esteps?

            I feel it has definitely improved by a large extent, will try calibrating e steps again.

            It was mentioned somewhere that e-steps need to be whole numbers and not fractions, is that true ?

              @hussainsail2002 I've used decimal without issue.

              ...but equally interested to see if there is anything more than circumstantial evidence showing otherwise.
