Hi 3d printer gurus,
My Kossel-based printer is back up and running - however I am facing some oozing issues, mainly in the form of ‘blobs’ of plastic that form on the outside shell. Picture incoming, but it is almost certainly what is described here.
I did address this once upon a time, but having lost my previous laptop and the magical Cura settings that I had on it, I’m starting from scratch.
Cura also seems to have some new settings since I last used it - one under ‘Experimental’ is coasting, which seems right down my street (stopping extrusion a little before finishing a move, so the oozing is used to print).
My question is simple - has anyone found a particularly good test print for oozing/stringing/retraction at all? It doesn’t help that I have an E3D Volcano hotend with large nozzle diameters (I am currently testing with 0.6mm), or a relatively long bowden tube, but it would be nice if I can get the retraction settings dialed in. Any recommendations would be very helpful 
My printer is dimensionally very accurate and flat, all my problems now seem to be down to extrusion - so almost there!
