Step by Step
- Decide_what_function_your_circuit_board_should_have
- Design the circuit board or select and download a cad file from the hello-world circuits section on the http://fab.cba.mit.edu/about/fab/ or from hello world electronics
- Get copper foil ready in the CAMM machine
- Open Cad.py software
- Click input and get the design file (.cad file) or a pre-designed png file.
Settings on machine
- Select Roll and press enter on machine
- Press Force, select 40 gf
Make the toolpath
- Open CAD.py in a Linux Terminal or click on the shortcut launcher in desktop.
- Make the toolpath for the circuit.
- Click CAM
- Click Output format and choose .camm (CAMM)
- If you're using a circuit board written in Python, you'll find a line near the bottom saying "#dpi = 500 ".
- Move the ("#") sign to the line above which is "dpi=200
- The "#" symbol is a comment, which will ignore the line of the command after the sign.
- Use "dpi = 200 # low resolution for previewing" for previewing toolpath contour
- Use "dpi = 500 # high resolution for machining" actual rendering and sending to Modela (takes longer to render)
- Set contours to 1 (meaning 1 outline)
- tool diameter. 0.01
- tool overlap 0.5
- force 45
- velocity 2
- Click Contour
- This will set the toolpath for the file
- Now you you should click send to machine
- Note, Force settings can be variable between time and machines.
- In Vestmannaeyjar, Iceland Fab Lab we have been using Force 70 on the machine.
