    Question Newbie Question

    Hi all
    I am trying to print circular parts on a dreamer and keep getting what looks like a bump in the radius of the part.
    Any ideas would be most appreciated

    The bump is where the print head has changed layers. There is no way to get rid of the bump only to make it less visble by hiding it in some thing like a sharp corner or making the point where the layer change takes place random but that scaters tiny bumps all over the outer surface in cura slicer you can change this with the Z seam alignment command in Prusa slicer it is printer setting - advanced -seam position

    It's called a layer stitch. Or z-axis stitch or other things in that line.

    set the layers to start at a random point for each layer. Flashprint has this option :-)
    Also set retractions to happen during the wipe procedure, that way you cut down on any little bumps when the filament retracts.
