# Slicer4RTN RTN stands for [Rotating Tilted Nozzle](https://xyzdims.com/2021/01/27/3d-printing-rotating-tilted-nozzle-option/), a 4-axis 3D printer. Slicing4RTN is an Open Source implementation of a conic slicing procedure as invented by [ZHAW](https://zhaw.ch) (Elspass, Jaeger, Wuethrich, Gubser, Bos and Holdener) and became known as part of their [RotBot](https://www.zhaw.ch/en/medien/medienmitteilungen/detail-news-releases/event-news/upgrade-fuer-den-3d-drucker-spart-zeit-und-stuetzmaterial/) announcement in 2021/01. This software has been independently developed yet is comparable to the solution of ZHAW. [Conic Slicing for Rotating Tilted Nozzle (RTN) / 4 Axis](https://xyzdims.com/2021/02/26/3d-printing-conic-slicing-for-rotating-tilted-nozzle-rtn/) lays out more details of the slicing procedure and its application; and [Slicer4RTN](https://xyzdims.com/3d-printing/slicer4rtn/) contains a more thorough description of the features and details how to use `slicer4rtn`. **NOTE**: The software is in a very experimental state and defaults and settings might change during this early stage of development - please use caution when running the G-code on your 3-, 4- or 5-axis 3D printer, **don't do this unattended**. ## Limitations In its current state only slices in a single "conic mode" per model, either `outside`-cone printing or `inside`-cone printing (change with `--mode=..`) which means, only a single overhang reference is supported: conic slicing allows overhangs to be printed without support structure given they point away or to a central conic center; multiple centers are not yet supported which would require sub-volume segmenting and treat each sub-volume printed in its own mode. A future version of Slicer4RTN might segment volumes and support multiple conic centers and more complex overhang slicing - this is why this software is released as Open Source to help to push this development. ## Supported Platforms - Linux Ubuntu/Debian, tested on Ubuntu 20.04 LTS ## Updates - 0.6.0: $efa multiplier adjusted, --rot-revolve=0 (new default, unlimited revolv), --rot-revolve=1 (single revolv) does performs smart rotate-around to immitate continenous rotation - 0.5.2: --rotate, --scale and --translate added for pre-processing model - 0.5.1: experimentally support .off, .obj, both more compact than .stl - 0.5.0: fixing levelModel() affected CuraEngine/cura-slicer, version bump - 0.4.8: support of start-gcode and end-gcode - 0.4.7: cleaner X Y Z output - 0.4.6: adding support for 'cura-slicer' (CuraEngine wrapper https://github.com/Spiritdude/Cura-CLI-Wrapper) - 0.4.5: fixing config load for slic3r & prusa-slicer - 0.4.2: CuraEngine 4.4.x & CuraEngineLegacy (15.10) experimental support added - 0.4.0: supporting ~/.config/slicer4rtn/slicer4rtn.ini with new defaults - 0.3.4: rot_revolv=1 better $rot calculation (rot_revolv=0 untested) - 0.3.1: changing rot-offset 0 => -90 - 0.3.0: version bump with various cleanups, more consistent settings, --inter-steps added - 0.2.6: diverse new settings: rot_gcode, rot_offset, rot_revolv, tilt_gcode and layer-height which is computed for core-slicer - 0.2.5: added main $efa multiplier depends on angle, not yet sure if it's correct - 0.2.4: making arguments for core slicer easier, --slicer.= as well --= works (better for print3r integration) - 0.2.3: simplifying code, extrusion interpolation still off (needs reworking) - 0.2.0: changing extrusion calculation, better apprx., flow_rate => erate - 0.1.1: properly re-offset G-code output from slic3r and prusa-slicer as it centers model, early support for prusa-slicer - 0.1.0: new --slicer.key=val added, added --zoff=val to re-adjust zoffset in final G-code - 0.0.5: added --axis=3, 4 or 5 to create for 3-, 4- or 5-axis G-code 3d-printer, added --angle=45 to change angle of cone - 0.0.4: added --mode=outside or inside to reverse order for inside/outside-cone printing - 0.0.3: moving stl2rtn and gcodertn into slicer4rtn - 0.0.2: bug fixed, much better G-gcode output, viewable by Cura - 0.0.1: first functional version, various bugs ## Download ``` % git clone https://github.com/Spiritdude/Slicer4RTN % cd Slicer4RTN/ ``` ## Installation ``` % make requirements ``` if you want to install `slicer4rtn` system-wide: ``` % make install ``` which installs the app and sane defaults in `/usr/share/slicer4rtn/` but edit your personal settings per core slicer in `~/.config/slicer4rtn/` as those will not be overwritten in future upgrades with the same filename as in `/usr/share/slicer4rtn/`. ## Usage ``` % ./slicer4rtn USAGE Slicer4RTN 0.6.0: [] ... options: -v or --verbose increase verbosity --version display version and exit -k or --keep keep all temporary files (temp.stl, temp.gcode) --rotate= rotate model --translate= translate model --scale= scale uniform --scale= scale individually --recenter recenter model X- & Y-wise --subdivide= set midpoint subdivisions (default: 2) --mode= set cone mode, either 'outside' or 'inside' (default: 'outside') --output= override default naming convention file.stl -> file.gcode --axis= set axis count of printer: 3, 4 or 5 (default: 4) --angle= set angle of cone (default: 45) --center= set conic slicing center (default: 0,0) --bed-center= set bed-enter, only affects output G-code (default: 100,100) --layer-height= set conic layer height (default: 0.2) --rot-gcode= set G-code symbol for rotation (default: A) --rot-revolv= set rotation revolution, 0 = unlimited, 1 = once (default: 0) --rot-offset= set rotation offset (default: -90) --rot-fixed= set fixed rotation angle, usable if --axis=3 but 4-axis or 5-axis printer is target --tilt-gcode= set G-code symbol for tilt for 5-axis operation (default: B) --zoff= set z-offset, will be added to G1 ...
