There are test objects with a selection of features, including various angles and overhangs. Try printing without support then observe which angle it goes to a bird's nest. That's the minimum angle you can get away with printing without support. Of course there's a setting for that. Yup, the minimum angle for needing support can vary with nozzle diameter and extrusion %. Depends on if or how much the bead at the edge will overlap the layer below. Something else to note is it can't print any wall thinner than the nozzle diameter so the default is to simply not print any part that thin. There is (or should be) a setting to make it print such features as a single wall thickness. Seems obvious but 3D printing forums always get the question "Why won't it print my thin walls?"
When you get things dialed in, try vase mode. That prints a bottom layer (you can specify more than one bottom layer) then spirals up one wall thickness around the whole object, leaving off the top layer. Objects designed for vase mode print best with it, like vases. There's a 1950's style SciFi rocket made for this mode. Print your wife some vases. :) A thin coating of epoxy, clear lacquer, urethane etc on the inside will ensure it's water tight.

Something else to fiddle with. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
