![]() ![]() I modified the OpenSCAD code to extend the struts 0.1 mm inside the base and ran that model through the software stack, which produced not a single complaint about anything, anywhere. Oddly, Skeinview didn’t show any problems, so the G-Code was (presumably) OK.Įrror messages tend to make me twitchy, though. Judging from the messages, the problem ran all the way to the top of the struts. The usual searching suggested that sometimes Skeinforge has problems with coincident surfaces, such as between the motor mount plate and the struts and the base, or coincident edges where two blocks abut. ![]() Once the gcode is saved, you should check over the layer with a z of: Something will still be printed, but there is no guarantee that it will be the correct shape. ![]() Warning, the triangle mesh slice intersects itself in getLoopsFromCorrectMesh in triangle_mesh. Then run it through Skeinforge 40, which emits a flurry of messages along these lines: That produced an OpenSCAD model with positive surfaces for the various parts and negative surfaces inside the holes: NEMA 17 Mount - additive modelĬompile that through CGAL, export as STL, inhale into RepG 25, and you (well, I) get what looks to be a fine object in the preview pane: NEMA 17 RepG preview - additive Makes perfect sense to me perhaps I’m an additive kind of guy. The baseplate, minus two mounting holes.Two side struts to stiffen the motor plate.The motor mounting plate, less five holes.My first pass at the NEMA 17 motor mount bracket used additive modeling, glomming together several blocks made from cube primitives: ![]()
