Step 1: Designing the circuit
Step 2: Cutting the circuit
For the design:
- Make as many rounded curves as possible since the knife is not so good at cutting 90 degree angles
- Take as much space as possible between the components
- Make the copper lines as thick as possible
- if you have a lot of space between thin lines, draw some extra rectangle on the copper that will be weeded off afterwards. It is easier to tear off little pieces of copper at the time.
- I used force 40 and speed 1 cm/s.
- The copper comes on a sticker roll. To cut sharp straight lines you have to glue a piece of the copper sticker to a rigid cardboard first before placing it into the vinyl cutter.
- When the knife is running, some traces already start to curl up from the circuit and might be hit by the knife as it moves over. If this happens pause the machine and press the pieces back to the surface with tweezers.
