So for simple STLs choose subdivide=5 or higher, for already complex STLs with thousands of faces, you may go with the default. The current algorithm depends on sufficient detailed faces. Slicer4rtn model-6.stl -angle=25 -subdivide=5īy default the faces of model is 2x subdivided, you can turn it off by -subdivide=0 or increase like -subdivide=5 for a cube. Slicer4rtn overhang.stl -axis=3 -output=sample-belt-printer.gcode -fill-density=5 Slicer4rtn overhang.stl -axis=5 -output=sample.gcode Slicer4rtn overhang.stl -output=sample.gcode = all other arguments not for slicer4rtn will be passed to the core slicer (slic3r) slicer.= add additional slicer arguments, e.g. max-speed= set maximum speed (default: 0) motion-minz= set minimum Z level for motion (without extrusion) (default: 0.2) inter-steps= set interpolation steps per mm (default: 2) efmax= set extrusion factor maximum, (default: 3) efmin= set extrusion factor minimum, (default: 0.01) erate= set extrusion rate (multiplier, default: 1) zoff= set z-offset, will be added to G1. tilt-gcode= set G-code symbol for tilt for 5-axis operation (default: B) rot-fixed= set fixed rotation angle, usable if -axis=3 but 4-axis or 5-axis printer is target rot-offset= set rotation offset (default: -90) rot-revolv= set rotation revolution, 0 = unlimited, 1 = once (default: 1) rot-gcode= set G-code symbol for rotation (default: A) layer-height= set conic layer height (default: 0.2) bed-center= set bed-enter, only affects output G-code (default: 100,100) center= set conic slicing center (default: 0,0) axis= set axis count of printer: 3, 4 or 5 (default: 4) output= override default naming convention file.stl -> file.gcode mode= set cone mode, either 'outside' or 'inside' (default: 'outside') subdivide= set midpoint subdivisions (default: 2) k or -keep keep all temporary files (temp.stl, temp.gcode) Just keep your expectation on the print quality low, as you try to print with a vertical nozzle which is meant to be printed with a tilted nozzle, but you will be able to print 90° overhangs without support structure. printing 90° – 110° overhangs in one direction, like possible with a belt printerĪnd yes you can print non-planar conic sliced G-code with an ordinary 3-axis 3D printer if you dare, something like this:.unidirectional tilted slicing (tilted nozzle).printing 90° – 110° overhangs without support, given some conditions.Some of the conceptual thoughts on Conic Slicing for Rotating Tilted Nozzle (RTN). Slicer4RTN aka “Slicer for Rotating Tilted Nozzle (RTN)” is a highly experimental conic slicer utilizing existing planar slicer like Slic3r with pre- and post-processing to create G-code which can be printed with a 4-axis RTN, allowing to print particular overhangs without support:
