STEP 1: INSTALL REPLICATORG

ReplicatorG is the software used to drive the Makerbot 3D-printers. We use it to control our machines as well,
but create the machine code for cutting in CAD.PY.
Download and unpack the software from:
ReplicatorG

 

 

STEP 2: INSTALL THE DRIVER FOR REPLICATORG

miniCNC.XML for ReplicatorG25
miniCNC.XML for ReplicatorG24
Choose 'save target as' and unrar. There is a folder under the 'ReplicatorG' install directory called '\MACHINES" This XML-file should be placed there.

OPTIONAL:MILLING PROFILE FOR REPLICATORG AND SKEINFORGE35
MILLING
This file configures skeinforge for milling, if you want to do milling based on 3D-models. This is more complex and we advise to start with the the 2D python-script below.
Choose 'save target as' and unrar into the SF_35_profiles directory
On my machine, win7 and ReplicatorG24, this is ' C:\Users\Lieven\.replicatorg\sf_35_profiles' )

 

 

 

 

 

STEP3: INSTALL CAD.PY AND PYTHON

cad.py is a CAM program that can be used to generate g-code tool paths
for milling 2D and 3D objects. It operates on images instead of vector
formats like Gerber, DXF, or SVG, so you'll have to export your design
as a PNG image first.

To get this running, you need to install Python, a programming language. Unfortunately this can be quite a hastle.
To complicate things, you need to separately install a number of modules, which aren't available for every version of Python.

We got the software successfully running on windows 32-bit and 64-bit systems and on Ubuntu.

INSTALL PYTHON ON WINDOWS

Below are the links to Python and the needed modules. Start by installing Python 2.6 and try to get all modules working.
If you don't succeed, try Python 2.7.

Python 2.6:
http://www.python.org/download/releases/2.6/
or
http://wiki.python.org/moin/BeginnersGuide/Download

To run cad.py you will need python installed along with following modules

scipy: http://www.scipy.org/Download
numpy: http://numpy.scipy.org/

PIL (Python Image Library): http://www.pythonware.com/products/pil/
pySerial : http://pyserial.sourceforge.net/
Matplotlib : http://matplotlib.sourceforge.net/
Tkinter: http://tkinter.unpythonic.net/wiki/How_to_install_Tkinter

 

INSTALL PYTHON ON MAC

Python 2.5 works ok.
You should install the same modules as above, but not all modules are available in a 2.6 version.

 

INSTALL PYTHON ON UBUNTU

Python 2.6.6 (default ubuntu) works ok.

Dependencies for cad.py are:
sudo apt-get install python-scipy python-numpy python-tk python-imaging-tk

 

 

 

 

STEP4: THE CAD.PY SCRIPT
If you got Python installed correctly you should be able to run the files below, after downloading, by double-clicking the file. Alternatively, open the Python GUI (graphical user interface) and open the file from there.


This is the original cad.py script as distributed by MIT:
http://fab.cba.mit.edu/about/fab/dist/cad.py


EXPERIMENTAL
This is a version of cad.py we started adjusting for our own use:
version 2011-05-04: cad-2011-05-04.py (download and unrar)
version 2011-05-15: cad-2011-05-15.py (download and unrar))

 

If all else fails, and you can't get Python to run on your machine, here's a compilied version of the software for windows: CADPY.EXE for win32

CALIBRATION FILES

This rar-file includes bitmap and G-code for a 5x5cm square and a 5cm diameter circle, generated for a 2mm milling bit.

MARCH 27th 2013 -TIMELAB - GHENT - On Wednesday March 27th we will be presenting our big black machine. It is a 800x1000mm 3-axial milling machine intended for milling wood panels in the Ghent fablab. See http://www.timelab.org/nl/presentatie-zelfgebouwde-freesmachine

Everybody is welcome for a quiet drink and some loud milling, from 19h at timelab.

 

MARCH 25th 2013 - Way too long since we came back to our milling machines. Both me and Kurt have been busy running our respective labs and haven't been able to put as much time in our machines as we would want.

MARCH 20th 2013 - SHOP UPDATE - For now we are not distributing any kits of the miniCNC. The machine electronics are based around the old Makerbot Cupcake boards, which are no longer available. We are reworking the electronics to run off a set of Reprap electronics and a modified version of Pronterface.

JANUARI 30th 2012 - Lieven will be giving a workshop/presentation of the miniCNC at the Antwerp Hackerspace.on Friday the 10th of Februari, 8PM.
See http://voidwarranties.be/index.php/Mini-cnc_workshopfor details.


SEPTEMBER 27th 2011- Adam W.-Swicizinsky und Ewald Neuhofer from AWS design team are taking the machine to the Vienna design week to engrave furniture, from September 30th to October 3rd, themed "Copyright - Design zwischen Inspiration und Kopie"
You can follow them on their project blog: http://awsdesignteam.wordpress.com
