    Has anyone successfully printed NinjaFlex on the Hemera with little or no stringing and can share their retraction settings with me? I just printed a wallet and it was very blobby and stringy.

    Hi Rocky,

    I would recommend a starting value of 0.5mm, of which you can incrementally increase up to 2mm. If you are still experiencing stringing/ blobbing then reduce the printing temperature, if that still does not sort the issue then you should look at drying your filament out/ improve your part cooling.

    Thanks for the reply. I am still having a lot of stringing. What retraction speed should I use? What about wipe and z-lift?

    Retraction speed of 40mm/s is suitable for Hemera, wipe possibly would help - I don't have a figure for you it's a case of seeing what works best for your setup with these values. Have you tried without Z hop?
