RepRapPro Software to run our 3D printers
Python Other

RepRapPro version of

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

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


This repository includes a pre-compiled version of Pronterface for Windows, the original Python-based Printrun files, and scripts to run pronterface in Windows and Linux, for Fisher, Huxley, Mendel and Ormerod printers, with variations for the electronics supplied (Duet/Melzi).

To install, download the ZIP and extract to a sensible place, or clone the repository. To run:

  • On Windows, run the relevant .cmd script.
  • On Linux, install dependencies (see below), then run the relevant .sh script
  • On Apple OS X, install dependencies (see below), then run pronterface/


For your convenience, pre-compiled versions of Pronterface are available. If you use a pre-compiled version of Pronterface, you do not need to 'install dependencies', which is the next step of the instructions. Just run the application.


A precompiled version is supplied in this repository, in the 'Win7' folder. Run 'pronterface.exe'.

Apple OS X

A precompiled version is available here: Download, extract, and run the Pronterface application.


If you prefer to run the Python-based application in the 'pronterface' folder, rather than any pre-compiled version, you need to install support files (called 'dependencies') for it to run.


sudo apt-get install python-serial python-wxgtk2.8 python-pyglet python-tk

Fedora 15

sudo yum install pyserial wxpython pyglet


Download the following, and install in this order:


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 install

Mac OS X 10.7 (Lion) and later

  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: Known to work PythonWX:
  3. Download and unpack pyserial from
  4. In a terminal, change to the folder you unzipped to, then type in: sudo python install
  5. Repeat 4. with http://

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 10.6 (Snow Leopard) and earlier

  1. Download and install
  2. Grab the source for pyserial from
  3. Unzip pyserial to a folder. Then, in a terminal, change to the folder you unzipped to, then type in:

    defaults write Prefer-32-Bit -bool yes

    sudo python install

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

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


sudo python install

Then repeat the same with http://


To use pronterface, you need:

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

Download and install the above (as covered in the 'Installing dependencies' instructions above. Start pronterface by running Select the port name you are using from the first drop-down, select your baud rate, and hit connect. Load a GCODE file. 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.


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


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 for a simple command-line sender, or the following code example:

p.startprint(data) # data is an array of gcode lines
p.send_now("M105") # sends M105 as soon as possible
