platsch / slic3r

G-code generator for 3D printers (RepRap, Makerbot, Ultimaker etc.)

Slic3r Electronics

This is a modified version of Slic3r which supports the integration and routing of electronic components and wires into 3D printable objects. Your printer should be equipped with an additional extruder for conductive paste to generate wires and (optional) a vacuum gripper / cameras for automatic component placing. OctoPNP can be used to control the interactive pick'n place system and for optical calibration.

Import schematics

The electronics extension currently supports the XML-based Eagle .sch format to import electronic schematics. Importing a schematic will add all components to the list of unplaced parts and generate the connection graph. Use left-doubleclick on parts, rubberbands and waypoints for placing and routing, right-doubleclick to remove things.

Export designs

The position of all placed components and waypoints can be ex-/imported to a .3de file. This file must be stored in the same location as the .sch file since it referes to the original schematic for part geometries, connections and unplaced parts.

Settings

• print settings->Multiple extruders->Conductive wire extruder to select the extruder with conductive material
• print settings->Speed->Conductive wires to set appropriate extrusion speed for conductive material (typically much lower than plastic extrusion speed)
• print settings->3D Electronics to configure channel widths and offsets

As a starting point, the profile for our developer machine can be found under https://github.com/platsch/Slic3r-Electronics-Config

Slic3r

Slic3r itself is mainly a toolpath generator for 3D printers: it reads 3D models (STL, OBJ, AMF) and it converts them into G-code instructions for 3D printers.

for further information on Slic3r, installation and build instructions please refer to the upstream project https://github.com/alexrj/Slic3r or the Slic3r project homepage

How to install?

If you want to compile the source yourself follow the instructions on one of these wiki pages:

• Linux
• Windows
• Mac OSX

all electronics branches additionally require the libxml2-dev and libxml-perl packages.

Directory structure

• Build.PL: this script installs dependencies into local-lib/, compiles the C++ part and runs tests
• lib/: the Perl code
• package/: the scripts used for packaging the executables
• slic3r.pl: the main executable script, launching the GUI and providing the CLI
• src/: the C++ source of the slic3r executable the and CMake definition file for compiling it (note that this C++ slic3r executable can do many things but can't generate G-code yet because the porting isn't finished yet - the main executable is slic3r.pl)
• t/: the test suite
• utils/: various useful scripts
• xs/src/libslic3r/: C++ sources for libslic3r
• xs/src/slic3r/: C++ sources for the Slic3r GUI application
• xs/t/: test suite for libslic3r
• xs/xsp/: bindings for calling libslic3r from Perl (XS)

slic3r's Issues

Missing libxml dependency

Version

Current HEAD: 19f5cdd

Operating system type + version

Linux / Ubuntu 16.04

Behavior

Build.pl fails due to missing XML::LibXML dependency.
The LibXML perl library is used solely by the EAGLE .sch importer which should be ported to C++.
All other XML interactions are done by pugixml.

Quick fix:
sudo apt install libxml2-dev

@Zip-o-mat FYI.

Disappearing of part in 3D Electronics

Version

0.9.9-3415-g19f5cdd

Operating system type + version

Ubuntu 16.04 LTS

Behavior

• Describe the problem
  When Placing a electronic part and moving it after first placement the whole part is disappearing and just the coordinate axes are shown.
  When you further move the part with the buttons on the lower left corner the part is appearing again.

• Steps needed to reproduce the problem
  just place a electronic part on the base part and move it.

• Expected Results
  no disappearing of the whole part

  • Screenshots from Slic3r preview are preferred
    Diasappeared part:
    
    Appeared part:

X/Y rotation of SMD-components results in wrong Z-position

Version

19f5cdd

Behavior

Rotating a component around X or Y axis (e.g. to place it with it's pins at the top) results in a wrong z-position of both, the component itself and all pin-waypoints.
For the component: it is not clear how the position should be modeled, at the bottom? COM?
For the pins: the rotation is simply not considered when generating the relative pin positions.

Ink drops at unwired pins

Feature: option to generate ink drops for unwired pins to improve bonding

Rotation orientation wrong

Behavior

Z-Rotation of SMD-components is inverted. A positive rotation is expected to turn the part clockwise, but does CCW instead.

Electronics extension per object on the plater

Open and display a separate schematic for each object on the plater. This might also affect the gcode generation.
This behavior is already implemented but damaged by a number of recent modifications.
