MILLING

We used Ubuntu Linux to host Fab modules to generate tool-path for milling of the board. I used Ubuntu as "su" user

Next, I changed "from input format" to "image(.png), and "to output process" to "Roland MDX-20 mill (.rml)" and then clicking on "make_png_rml" opens a new window

Next step was to import the image for trace tool-path. I used an image that was generated last year at FabLab Cept

Next I adjusted the following settings:

Type: 3D plane    (this allows the the movement of axis in z direction)

Diameter : 0.4mm (1/64inch)    (here we specify the diameter of our milling bit, ideally should b 1/64in for milling and 1/32in for cutting)

Offsets : 3mm    (defines the offset of movement of the bit around white lines)

Overlap : 0.5

Error : 0 pixels

Intensity : 0.5

Z(mm) : -0.1

Next I adjusted the xmin and ymin to adjust the origin of the bit as I was using a board which already had somebody else's circuit

Next click on "make.path" and then on "make.rml" to start the milling

I could also see the progress of the milling on the screen

Since this is my first time with electronics, I wanted to try making another circuit too. So I changed the offset to "4" and shifted the origin to start milling again.

Finally I had 2 milled boards
