Board one should be cut face/color up while board two should be cut face down. We ended up flipping some of the pieces, but it just adds more character to the machine that we are making.
Etched lines cut top latey and corrugation but not through bottom layer. To achieve that, we ran a test round and decided on the configuration.
We cut enough parts to make four sets of axes.
First of all, group the parts according to their colors.
Folding and gluing the parts together.
Aluminum shaft were cut.
Put in motor and aluminum shaft into the cardboard frame.
Clippers, markers and weight were our friends in assembling the axis.
Tool Path: The tool path was generated as a string of coordinates in the format [[x0,y0],[x1,y1],[x2,y2]]. The team developed a number of tool paths as NURBS curves in Rhino, sized to fit the workspace of approximately 200 x 200mm. These curves were then imported into Grasshopper, where they were divided into hundreds of waypoints. These points were then lexically formatted into the format accepted by the python code.
We decided to use Andrew's rainbow board as our end
This was our first two-axis movement
We set up a camera in bulb mode to allow for long exposure times our project required. The sprial toolpath took about 3 minutes to complete, the "Hello" toolpath took about 2.5 minutes. Bulb mode allows the shutter of the camera to stay open for as long as the shutter release button is depressed.
