Saftey Rules for the Shotbot CNC Machine:

Don’t start without Henk, Michelle or Asli
Always first Z-level the machine
Don’t turn on the spindle
Never leave the machine running
Clean up ink spills immediately (pause the machine)
If unsure, do a test run in the air
No material near the rails / gears of the machine
Keep it simple stupid

OPEN SOURCE HARDWARE

Lecture by Sara Diaz Rodriguez

How to work with open source hardware?

Understand how existing machines work Get to know and overcome your knowledge gap Practice user testing and impact analysis

Documentation

Create a list of materials, an estimate cost, add datasheets Design bluprints, drawings, shcematics, source codes, assembly guides Separate the process into steps and write a summary of the overview of the process Use universal file formats like pdf, dxf, stl. Formats of open software Take pictures in white background and make step by step instructions and gifs Create a video showing the machine functioning....

Safety

Brave hacker, whatever you do..

Don't start without Henk, Michelle or Asli Always first z-level the machine Don't turn on the spindle Never leave the machine running Clean up ink spills immediately (pause the machine) If unsure, do a test run in the air No material near the rails/gears of the machine Keep it simple stupid (kiss) References & examples

Project: Hacking CNC ShopBot Machine for Artistic Expression

Overview:

The project involved modifying a CNC ShopBot machine, a Computer Numerical Control milling machine designed for precise material milling. Instead of utilizing a traditional drill bit, the goal was to attach a painting device to the CNC, enabling it to create artistic drawings.

Objectives:

Transform the CNC ShopBot for artistic applications. Replace the conventional drill bit with a painting device.

Design Process:

Utilize Rhino for creating intricate and artistic designs. Generate G-code instructions compatible with the CNC machine.

Artistic Expression:

Explore the machine's capacity for drawing and painting. Expect and embrace surprises in the artistic output.

Components Used:

Hardware: Corrugated perforated iron band (1 spool) Self-Adhesive Rubber Seal (1 roll) Cable ties (plenty) Clamp (2) Nuts and bolts of various sizes (plenty) Bike phone holder attachment (1) Threaded insert (1) Servo motor & pen holder attachment (1, 3D printed with PLA)

Electronics:

Arduino Uno (1)
Attiny85 (1)
Attiny85 dip socket (1)
Battery pack (1)
Breadboard (1)
Jumper wires (plenty)
AA battery (3)
Solder

Ink/Pigment: - Ecoline ink (various colors, plenty) - Sicotex screenprinting ink (various colors, plenty) - Acrylic paint (various colors, plenty)

Brushes and Tools:

Various brushes
Various sponges
Various molotovs
Pipets
Marker pens
Scraper
Squeegee

Surface Materials: - Paper (A2 size) - Cotton fabric with acrylic gesso primer - 120 gr copy paper (A3 size)

Software: - Arduino IDE (for programming Attiny45 for servo motor) - Rhinoceros (to prepare design files) - Grasshopper (to create custom shopbot code) - VCarve Pro (to prepare toolpath for the shopbot) - Shopbot Console (to communicate with the CNC machine)

Project Outcome:¶

The project aimed to push the boundaries of the CNC ShopBot machine, turning it into a tool for artistic expression. By combining precise CNC technology with creative design, the team expected the machine to draw, paint, and surprise them with unique and unexpected results.

Workflow & Experiments¶

Trailer Movie

Documentary Title: "HACKING UNIVERSAL: The CNC ShopBot Experiment" "art in motion"

Visual Style:

Utilize a mix of documentary-style interviews, behind-the-scenes footage, and close-up shots of the CNC machine in action.
Incorporate vibrant colors to capture the essence of artistic expression.
Use visual effects to emphasize the contrast between the precision of the CNC and the organic nature of art.

Tone: - humorous, entertaining, visual, chaotic, inspiring yet blending technical insights with the joy of artistic creation, celebrate the beauty of unpredictability in art.

Music: - Energetic and uplifting music during moments of experimentation and discovery. - Reflective and contemplative tunes for interviews and reflective segments.

This movie board serves as a blueprint for a documentary that explores the educational and artistic dimensions of hacking a CNC ShopBot machine for creative expression.

H A R D W A R E¶

Mechanics - How to connect brushes etc to the ShopBot
How humans vs machines hold pens (angle vs straight up, fluid vs mechanic movement, idea vs programmed)

C O N S I D E R¶

Things to think about when designing the hardware:
Size (of brush / shape / thickness)
Secure (tightly held in place)
Pressure (does it need a gentle brush or a heavy sweep)
Angle (straight down or adjustable angle)
Movement (incorporated into hardware)
Reservoir (included for ink etc built in)
Weight (will weight be an issue?)

HAIR Brush-Making

**Making Human Hair Paint Brushes** (youtube tutorial I watched)

**Hair Brush Textures**

DIY INSTRUCTIONS WITH RAY & CHAT BTG

Materials:

Fibres / Hair / or any other works just fine

TIP (start with a small amount; human hair works well)
Liquid glue
Wodden Stick
String
Needle and thread (Optional for more complexity)
Wax

Step-by-Step Procedure:

**COLLECTING/CUTTIN FIBRES** --> CUT the Hair/ @JIAWEN.WONG THANKS FOR THE DONATION

Collect a small amount of hair. Ensure it's clean and free of any products. Trim the hair to a manageable length, depending on the desired brush size. Create the Brush Base:

Take a stick of appropriate length for the handle of your brush. Apply liquid glue to one end of the stick.

Attach the Hair:

Arrange the trimmed hair neatly and evenly. Press the arranged hair onto the glued end of the stick, ensuring it adheres securely.

Wrap with String:

Once the hair is attached, tightly wrap string around the base of the hair where it meets the stick. Continue wrapping until the string is secure and forms a tight bundle.

Apply Additional Glue:

Apply more liquid glue to the wrapped area. This helps secure the hair and string in place.

Let It Dry:

Allow the glue to dry completely. This might take some time, so be patient.

**Optional: Add Reinforcement (Needle and Thread):

Add Wax:

Apply a thin layer of wax to the entire brush, including the wrapped area and the base of the hair. This helps protect and seal the materials.

For a more durable brush, you can reinforce the hair attachment by sewing through the wrapped area using a needle and thread.

HACK-ing ELECTRICITY

*+credits to our amazing team member Riley Cox and her passion with electricty for delving into making our project ever more intresting:

"Servo Motors and Electronic addons¶ To add an extra variable to our CNC hacking adventure, we decided to make an adapter to add a servo motor to the brush attachment allowing for extra movement and more complex mark-making. I haven't worked with servo motors before so I was really excited to get to play around with them. Servo motors are actuators that allow for precise control of position/angle."
