How to deal with retraction blobbing

Recommended Posts

Hey guys, what setting in Cura deals with blobbing from retractions.

I have my retractions dialed in, temp dialed in, speed dialed in, and get near-perfect prints, but on retraction it has a bit of blobbing (just enough that its a problem). Zero stringing or any other issues with the dialed in settings.

Printing ninjaflex on a modified UM2.

I'd love to take a look at those dialed in settings for NinjaFlex. It's a very tricky material to print and if you've dialed it in near perfect that would be very valuable to all users.

And if the blobs need special lenses to show up in a picture I'm not sure i would call that a problem heh.

Correct already printing at very low speed, from 10-15 depending of the print. With some finicking and tweaking there's zero stringing, but some blobbing.

This isn't on a UM2 by any means, you can't get high quality prints on a bowden system with ninjaflex/filaflex. Tried all aftermarket extruders, you can get by, but can't get the quality for a professional print. Had to add another system to get to that level.
