Z-seam Optimization ringing / ghosting
thingiverse
***What*** A way to reduce ringing by adding a small groove to a model and aligning the Z-seam to it. ***How*** -Load the STL file into a slicer (I used Cura) -Make sure walls are printed counter clockwise (default in Cura). -Align the seam to the groove, Cura instructions below: Set the Z-seam settings to "User specified" Check "Z-seam relative" Set Z-seam Y to -1 or any value that is within the diameter of the model. A value outside the diamater also works but will not be quite as good. (Y may need top be replaced by X and or the " - " removed on some printers depending on your axes) -Set your speed settings high enough to show ringing, I used an Outer wall speed of 35mm/s and a Jerk of 15. -Print, preferably with a shiny filament. ***Results*** Try editing the depth and angle of the groove in the Fusion 360 file to get an even better result. Post a make if this worked for you and let me know what depth and angle you used :) Perhaps a similar function could be added to Cura or other slicers "Start and stop point inset"? ***Videos*** https://youtu.be/X52aTNTnfR4 https://youtu.be/0UkF1EPs-Nk https://youtu.be/3qegsbIARvU
