# GPX
GPX was created by Dr. Henry Thomas (aka Wingcommander) in April 2013
GPX is a post processing utility for converting gcode output from 3D slicing software like
Cura, KISSlicer, S3DCreator and Slic3r to x3g files for standalone 3D printing on Makerbot
Cupcake, ThingOMatic, and Replicator 1/2/2x printers - with support for both stock and
sailfish firmwares. My hope is that is little utility will open up Makerbot 3D printers to
a range of new and exciting sources and utilities for 3D printing input.
# Installation
## Linux
```
sudo apt-get install gpx
```
## Windows
* Download a release .zip file from [GPX
releases](https://github.com/markwal/GPX/releases)
* Copy gpx.exe from the .zip file to somewhere on your path.
*or*
If you'd prefer an installer, you may want to install GPX via
[GpxUi](https://markwal.github.io/GpxUi)
## Mac
* Download a release .dmg file from [GPX releases](https://github.com/markwal/GPX/releases)
* Open up the .dmg file and drag the gpx application to /usr/local/bin or somewhere on your PATH
*or* via *homebrew*:
`brew install gpx`
*or* with a GUI:
[GpxUi](https://markwal.github.io/GpxUi)
# Installing from source
You need to have the GNU tools already installed and configured on your machine.
For Windows, mingw or cygwin. For Linux, `sudo apt-get install
build-essential`. For Mac, perhaps: Xcode menu > Preferences > Downloads >
Command Line Tools.
```
git clone https://github.com/markwal/GPX
cd GPX
mkdir build
cd build
../configure
make
sudo make install
```

# Usage
```
gpx [-CFdgilpqrtvw] [-b BAUDRATE] [-c CONFIG] [-e EEPROM] [-f DIAMETER] [-m MACHINE] [-N h|t|ht] [-n SCALE] [-x X] [-y Y] [-z Z] IN [OUT]
Options:
-C Create temporary file with a copy of the machine configuration
-F write X3G on-wire framing data to output file
-N Disable writing of the X3G header (start build notice),
tail (end build notice), or both
-d simulated ditto printing
-g Makerbot/ReplicatorG GCODE flavor
-i enable stdin and stdout support for command line pipes
-l log to file
-p override build percentage
-q quiet mode
-r Reprap GCODE flavor
-t truncate filename (DOS 8.3 format)
-v verbose mode
-w rewrite 5d extrusion values
CONFIG: the filename of a custom machine definition (ini file)
EEPROM: the filename of an eeprom settings definition (ini file)
DIAMETER: the actual filament diameter in the printer
MACHINE: the predefined machine type
some machine definitions have been updated with corrected steps per mm
the original can be selected by prefixing o to the machine id
(or1, or1d, or2, or2h, orx, ot7, ot7d)
c3 = Cupcake Gen3 XYZ, Mk5/6 + Gen4 Extruder
c4 = Cupcake Gen4 XYZ, Mk5/6 + Gen4 Extruder
cp4 = Cupcake Pololu XYZ, Mk5/6 + Gen4 Extruder
cpp = Cupcake Pololu XYZ, Mk5/6 + Pololu Extruder
cxy = Core-XY with HBP - single extruder
cxysz = Core-XY with HBP - single extruder, slow Z
cr1 = Clone R1 Single with HBP
cr1d = Clone R1 Dual with HBP
r1 = Replicator 1 - single extruder
r1d = Replicator 1 - dual extruder
r2 = Replicator 2 (default)
r2h = Replicator 2 with HBP
r2x = Replicator 2X
t6 = TOM Mk6 - single extruder
t7 = TOM Mk7 - single extruder
t7d = TOM Mk7 - dual extruder
z = ZYYX - single extruder
zd = ZYYX - dual extruder
fcp = FlashForge Creator Pro
SCALE: the coordinate system scale for the conversion (ABS = 1.0035)
X,Y & Z: the coordinate system offsets for the conversion
X = the x axis offset
Y = the y axis offset
Z = the z axis offset
IN: the name of the sliced gcode input filename
OUT: the name of the X3G output filename
specify '--' to write to stdout
Examples:
gpx -p -m r2 my-sliced-model.gcode
gpx -c custom-tom.ini example.gcode /volumes/things/example.x3g
gpx -x 3 -y -3 offset-model.gcode
```
