README.md

Printrun consists of printcore, pronsole and pronterface, and a small collection of helpful scripts.

  • printcore.py is a library that makes writing reprap hosts easy
  • pronsole.py is an interactive command-line host software with tabcompletion goodness
  • pronterface.py is a graphical host software with the same functionality as pronsole

GETTING PRINTRUN

This section suggests using precompiled binaries, this way you get everything bundled into one single package for an easy installation.

If you want the newest, shiniest features, you can run Printrun from source using the instructions further down this README.

Windows

A precompiled version is available at http://koti.kapsi.fi/~kliment/printrun/

Mac OS X

A precompiled version is available at http://koti.kapsi.fi/~kliment/printrun/

Linux

Ubuntu/Debian

You can run Printrun directly from source, as there are no packages available yet. Fetch and install the dependencies using

  1. sudo apt-get install python-serial python-wxgtk2.8 python-pyglet python-tornado python-setuptools python-libxml2 python-gobject avahi-daemon libavahi-compat-libdnssd1

Fedora

You can install Printrun from official packages. Install the whole package using

sudo yum install printrun

Or get only apps you need by

sudo yum install pronsole or pronterface or plater

Adding --enablerepo updates-testing option to yum might give you newer packages (but also not very tested).

You can also run Printrun directly from source, if the packages are too old for you. Fetch and install the dependencies using

  1. sudo yum install pyserial wxPython python-pyglet python-cairosvg

Optional: sudo yum install skeinforge simarrange

Archlinux

Packages are available in AUR. Just run

yaourt printrun

and enjoy the pronterface, pronsole, ... commands directly.

RUNNING FROM SOURCE

Run Printrun for source if you want to test out the latest features.

Dependencies

To use pronterface, you need:

  • python (ideally 2.6.x or 2.7.x),
  • pyserial (or python-serial on ubuntu/debian)
  • pyreadline (not needed on Linux) and
  • argparse (installed by default with python >= 2.7)
  • wxPython (some features such as Tabbed mode work better with wx 2.9)
  • pyglet
  • numpy (for 3D view)
  • pycairo (to use Projector feature)
  • cairosvg (to use Projector feature)

Please see specific instructions for Windows and Mac OS X below. Under Linux, you should use your package manager directly (see the "GETTING PRINTRUN" section), or pip:

pip install -r requirements.txt

Cython-based G-Code parser

Printrun default G-Code parser is quite memory hungry, but we also provide a much lighter one which just needs an extra build-time dependency (Cython), plus compiling the extension with:

python setup.py build_ext --inplace

Windows

Download the following, and install in this order:

  1. http://python.org/ftp/python/2.7.2/python-2.7.2.msi
  2. http://pypi.python.org/packages/any/p/pyserial/pyserial-2.5.win32.exe
  3. http://downloads.sourceforge.net/wxpython/wxPython2.8-win32-unicode-2.8.12.0-py27.exe
  4. https://pypi.python.org/packages/any/p/pyreadline/pyreadline-1.7.1.win32.exe
  5. http://pyglet.googlecode.com/files/pyglet-1.1.4.zip

For the last one, you will need to unpack it, open a command terminal, go into the the directory you unpacked it in and run python setup.py install

Mac OS X Lion

  1. Ensure that the active Python is the system version. (brew uninstall python or other appropriate incantations)
  2. Download an install [wxPython2.8-osx-unicode] matching to your python version (most likely 2.7 on Lion, check with: python --version) from: http://wxpython.org/download.php#stable Known to work PythonWX: http://superb-sea2.dl.sourceforge.net/project/wxpython/wxPython/2.8.12.1/wxPython2.8-osx-unicode-2.8.12.1-universal-py2.7.dmg
  3. Download and unpack pyserial from http://pypi.python.org/packages/source/p/pyserial/pyserial-2.5.tar.gz
  4. In a terminal, change to the folder you unzipped to, then type in: sudo python setup.py install
  5. Repeat 4. with http://http://pyglet.googlecode.com/files/pyglet-1.1.4.zip

The tools will probably run just fine in 64bit on Lion, you don't need to mess with any of the 32bit settings. In case they don't, try

  1. export VERSIONER_PYTHON_PREFER_32_BIT=yes in a terminal before running Pronterface

Mac OS X (pre Lion)

A precompiled version is available at http://koti.kapsi.fi/~kliment/printrun/

  1. Download and install http://downloads.sourceforge.net/wxpython/wxPython2.8-osx-unicode-2.8.12.0-universal-py2.6.dmg
  2. Grab the source for pyserial from http://pypi.python.org/packages/source/p/pyserial/pyserial-2.5.tar.gz
  3. Unzip pyserial to a folder. Then, in a terminal, change to the folder you unzipped to, then type in:

    defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

    sudo python setup.py install

Alternatively, you can run python in 32 bit mode by setting the following environment variable before running the setup.py command:

This alternative approach is confirmed to work on Mac OS X 10.6.8.

export VERSIONER_PYTHON_PREFER_32_BIT=yes

sudo python setup.py install

Then repeat the same with http://http://pyglet.googlecode.com/files/pyglet-1.1.4.zip

USING PRINTRUN

USING PRONTERFACE

When you're done setting up Printrun, you can start pronterface.py in the directory you unpacked it. Select the port name you are using from the first drop-down, select your baud rate, and hit connect. Load an STL (see the note on skeinforge below) or GCODE file, and you can upload it to SD or print it directly. The "monitor printer" function, when enabled, checks the printer state (temperatures, SD print progress) every 3 seconds. The command box recognizes all pronsole commands, but has no tabcompletion.

If you want to load stl files, you need to install a slicing program such as Slic3r and add its path to the settings. See the Slic3r readme for more details on integration.

USING PRONSOLE

To use pronsole, you need:

  • python (ideally 2.6.x or 2.7.x),
  • pyserial (or python-serial on ubuntu/debian) and
  • pyreadline (not needed on Linux)

Start pronsole and you will be greeted with a command prompt. Type help to view the available commands. All commands have internal help, which you can access by typing "help commandname", for example "help connect"

If you want to load stl files, you need to put a version of skeinforge (doesn't matter which one) in a folder called "skeinforge". The "skeinforge" folder must be in the same folder as pronsole.py

USING PRINTCORE

To use printcore you need python (ideally 2.6.x or 2.7.x) and pyserial (or python-serial on ubuntu/debian) See pronsole for an example of a full-featured host, the bottom of printcore.py for a simple command-line sender, or the following code example:

p=printcore('/dev/ttyUSB0',115200)
p.startprint(data) # data is an array of gcode lines
p.send_now("M105") # sends M105 as soon as possible
p.pause()
p.resume()
p.disconnect()

CONFIGURATION

Build dimensions

Build dimensions can be specified using the build_dimensions option (which can be graphically edited in Pronterface settings). This option is formed of 9 parameters: 3 for the build volume dimensions, 3 for the build volume coordinate system offset minimum, 3 for the endstop positions.

The default value is 200x200x100+0+0+0+0+0+0, which corresponds to a 200x200mm (width x height) bed with 100mm travel in Z (there are the first three numbers) and no offset. The absolute coordinates system origin (0,0,0) is at the bottom left corner on the bed surface, and the top right corner on the bed surface is (200,200,0).

A common practice is to have the origin of the coordinate system (0,0,0) at the center of the bed surface. This is achieved by using the next three parameters, for instance with 200x200x100-100-100+0+0+0+0. In this case, the bottom left corner of the bed will be at (-100,-100,0) and the top right one at (100,100,0).

These two sets of settings should be sufficient for most people. However, for some specific complicated setups and GCodes and some features, we might also need the endstops positions for perfect display. These positions (which are usually 0,0,0, so if you don't know you probably have a standard setup) are specified in absolute coordinates, so if you have your bed starting at (-100,-100,0) and your endstops are 10mm away from the bed left and right and the Z endstop 5mm above the bed, you'll want to set the endstops positions to (-110,-110,5) for this option.

USING MACROS AND CUSTOM BUTTONS

Macros in pronsole and pronterface

To send simple G-code (or pronsole command) sequence is as simple as entering them one by one in macro definition. If you want to use parameters for your macros, substitute them with {0} {1} {2} ... etc.

All macros are saved automatically immediately after being entered.

Example 1, simple one-line alias:

PC> macro where M114

Instead of having to remember the code to query position, you can query the position:

PC> where
X:25.00Y:11.43Z:5.11E:0.00

Example 2 - macros to switch between different slicer programs, using "set" command to change options:

PC> macro use_slicer
Enter macro using indented lines, end with empty line
..> set sliceoptscommand Slic3r/slic3r.exe --load slic3r.ini
..> set slicecommand Slic3r/slic3r.exe $s --load slic3r.ini --output $o
Macro 'use_slicer' defined
PC> macro use_sfact
..> set sliceoptscommand python skeinforge/skeinforge_application/skeinforge.py
..> set slicecommand python skeinforge/skeinforge_application/skeinforge_utilities/skeinforge_craft.py $s
Macro 'use_sfact' defined

Example 3, simple parametric macro:

PC> macro move_down_by
Enter macro using indented lines, end with empty line
..> G91
..> G1 Z-{0}
..> G92
..>

Invoke the macro to move the printhead down by 5 millimeters:

PC> move_down_by 5

For more powerful macro programming, it is possible to use python code escaping using ! symbol in front of macro commands. Note that this python code invocation also works in interactive prompt:

PC> !print "Hello, printer!"
Hello printer!

PC> macro debug_on !self.p.loud = 1
Macro 'debug_on' defined
PC> debug_on
PC> M114
SENT:  M114
X:0.00Y:0.00Z:0.00E:0.00 Count X:0.00Y:0.00Z:0.00
RECV:  X:0.00Y:0.00Z:0.00E:0.00 Count X:0.00Y:0.00Z:0.00
RECV:  ok

You can use macro command itself to create simple self-modify or toggle functionality:

Example: swapping two macros to implement toggle:

PC> macro toggle_debug_on
Enter macro using indented lines, end with empty line
..> !self.p.loud = 1
..> !print "Diagnostic information ON"
..> macro toggle_debug toggle_debug_off
..>
Macro 'toggle_debug_on' defined
PC> macro toggle_debug_off
Enter macro using indented lines, end with empty line
..> !self.p.loud = 0
..> !print "Diagnostic information OFF"
..> macro toggle_debug toggle_debug_on
..>
Macro 'toggle_debug_off' defined
PC> macro toggle_debug toggle_debug_on
Macro 'toggle_debug' defined

Now, each time we invoke "toggle_debug" macro, it toggles debug information on and off:

PC> toggle_debug
Diagnostic information ON

PC> toggle_debug
Diagnostic information OFF

When python code (using ! symbol) is used in macros, it is even possible to use blocks/conditionals/loops. It is okay to mix python code with pronsole commands, just keep the python indentation. For example, following macro toggles the diagnostic information similarily to the previous example:

!if self.p.loud:
  !self.p.loud = 0
  !print "Diagnostic information OFF"
!else:
  !self.p.loud = 1
  !print "Diagnostic information ON"

Macro parameters are available in '!'-escaped python code as locally defined list variable: arg[0] arg[1] ... arg[N]

All python code is executed in the context of the pronsole (or PronterWindow) object, so it is possible to use all internal variables and methods, which provide great deal of functionality. However the internal variables and methods are not very well documented and may be subject of change, as the program is developed. Therefore it is best to use pronsole commands, which easily contain majority of the functionality that might be needed.

Some useful python-mode-only variables:

!self.settings - contains all settings, e.g. 
  port (!self.settings.port), baudrate, xy_feedrate, e_feedrate, slicecommand, final_command, build_dimensions
  You can set them also via pronsole command "set", but you can query the values only via python code.
!self.p - printcore object (see USING PRINTCORE section for using printcore object)
!self.cur_button - if macro was invoked via custom button, the number of the custom button, e.g. for usage in "button" command
!self.gwindow - wx graphical interface object for pronterface (highly risky to use because the GUI implementation details may change a lot between versions)

Some useful methods:

!self.onecmd - invokes raw command, e.g. 
    !self.onecmd("move x 10")
    !self.onecmd("!print self.p.loud")
    !self.onecmd("button "+self.cur_button+" fanOFF /C cyan M107")
!self.project - invoke Projector

USING HOST COMMANDS

Pronsole and the console interface in Pronterface accept a number of commands which you can either use directly or inside your G-Code. To run a host command from inside a G-Code, simply prefix it with ;@.

List of available commands:

  • pause: pauses the print until the user resumes it
  • run_script scriptname [arg1 ...]: runs a custom script or program on the host computer. This can for instance be used to produce a sound to warn the user (e.g. run_script beep -r 2 on machines were the beep util is available), or to send an email or text message at the end of a print. The $s token can be used in the arguments to get the current gcode file name
  • run_gcode_script scripname [arg1 ...]: same as run_script, except that all lines displayed by the script will be interpreted in turn (so that G-Code lines will be immediately sent to the printer)
  • shell pythoncommand: run a python command (can also be achieved by doing !pythoncommand)
  • set option value: sets the value of an option, e.g. set mainviz 3D
  • connect
  • block_until_online: wait for the printer to be online. For instance you can do python pronsole.py -e "connect" -e "block_until_online" -e "upload object.gcode" to start pronsole, connect for the printer, wait for it to be online to start uploading the object.gcode file.
  • disconnect
  • load gcodefile
  • upload gcodefile target.g: upload gcodefile to target.g on the SD card
  • slice stlfile: slice stlfile and load the produced G-Code
  • print: print the currently loaded file
  • sdprint target.g: start a SD print
  • ls: list files on SD card
  • eta: display remaining print time
  • gettemp: get current printer temperatures
  • settemp: set hotend target temperature
  • bedtemp: set bed target temperature
  • monitor: monitor printer progress during a print
  • tool K: switch to tool K
  • move xK: move along x axis (works with other axes too)
  • extrude length [speed]
  • reverse length [speed]
  • home [axis]
  • off: turns off fans, motors, extruder, heatbed, power supply
  • exit
