Fab ISB – Part I: Milling Out The Board
Today I milled out my first PCB on the Modela. Technically it is not a “printed circuit board”, but machined out of copper-clad PCB stock.
Fab Academy Assignment
The assignment is to design a circuit board, mill it, and program it in assembly language. This post documents Part 1 of this process which entails:
- Designing the board (For this board I used the already created Fab ISB board file – I plan to design a board for a later project).
- Machining the board
Part 2 will document the process of putting the components into the board. Each student had to become acquainted with the following work flow:
- Stuffing components
- Programming
The first step in making a board is to create a tool path to send to the machine:
To Mill the Board:
- Import a PNG image into cad.py.
- Create the tool path in cad.py
- Send to the Modella
To Cut through the Board:
- Import the border PNG image into cad.py
- Create the tool path in cad.py
- Send to the Modella
