# 4. Computer controlled cutting
-This week I worked on defining my final project idea and started to getting used to the documentation process.
+**Goals**
-## Research
+This week we are focused on getting to know the laser cutter and vinyl cutting machine.

+Group assignment:
+1. Characterize your lasercutter's focus, power, speed, rate, kerf, joint clearance and types.

+Individual assignment:

-- [Markdown](https://en.wikipedia.org/wiki/Markdown)
+1. Cut something on the vinylcutter
+2. Design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf,
+which can be assembled in multiple ways and for extra credit include elements that aren't flat
-## Code Example
-Use the three backticks to separate code.
+**Accomplishments**
+
+ ## Parametric construction kit
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
- // initialize digital pin LED_BUILTIN as an output.
- pinMode(LED_BUILTIN, OUTPUT);
-}
+I decided to use Cuttle for this effort and like the idea of leveraging the number of sides as a key
+part of the parametric design
-// the loop function runs over and over again forever
-void loop() {
- digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
- delay(1000); // wait for a second
- digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
- delay(1000); // wait for a second
-}
-```
+I am going to use cardboard for this kit and so I was worried about the logjavity of the different
+joints and so I decided to use the chamfer joint.
-## Gallery
+
-
+Next I defined the parameters I expected to use
-## Video
+
-### From Vimeo
+I started with using the rectangle shape using the round corner
-<iframe src="https://player.vimeo.com/video/10048961" width="640" height="480" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

+
-### From Youtube
+When i started to play around the the parameter value i did not like how the round corners looked
+and I decided to move the connector from the middle of the leg to the corner using the pentagon shape
+this will allow easier scaling up and down in the number of sides. I also change my approach to the
+chamfer and replaced the rounded corder with a triangle cut out.
-<iframe width="560" height="315" src="https://www.youtube.com/embed/jjNgJFemlC4" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
+So starting over looked like this:
-## 3D Models

-<div class="sketchfab-embed-wrapper"><iframe width="640" height="480" src="https://sketchfab.com/models/658c8f8a2f3042c3ad7bdedd83f1c915/embed" frameborder="0" allow="autoplay; fullscreen; vr" mozallowfullscreen="true" webkitallowfullscreen="true"></iframe>
+I figured out that a lot of the issues I had with the boolean union/difference had to do with the order
+in which I had the object in the group

+
+
+
+Any once I combined them we got the shape I was looking for
+
+
+
+Now i worked through the rest with my goal being to me able to change the shape by increasing the number of
+sides. I used the sides parameter as both the driver of the number of sides and the repeat of the slots which
+worked well as you can see in the video:
+
+
+
+I then used the tile repeat to make a sheet
+
+
+
+
+I had set the slots depth and width as parameters as well as tne kerf as I was working on a number of different
+laser cutters and would adjust as needed.
+
+And now it is time for the test cut
+
+
+
+
+
+and they DO NOT FIT!!! a quick investigation shows my mistake. I set the slot width to 3mm but the cardboard
+i was using was 4mm.
+
+That was an easy change in the width parameter.
+
+I also felt like I needed something more to help make this a "kit" so I decided to add a hole in the middle
+
+
+
+and I downloaded a a number of shapes triangle, square etc and got to cutting
+
+
+
+It is time for real user testing for which I enlisted my younger 2 kids Avi and Ari:
+
+
+
+
+
+## Vinyl cutter
+
+
+ I wanted to make a sticker of Albert Einstien. I have a painting in my office that was
+ given to me as a gift and I really chriesh but it was a bit too complicated to replicate so
+ I started to look for another picture
+
+
+
+I choose 2 of these as option but I knew I needed to trace it to get it to a place where I can
+export to SVG and cut but saw all different type of trace options
+
+ 
+
+ I tried all types on 2 different images
+
+ 
+
+ I think I found that the **line art** is the best option est as I was going to do a multi colored sticker
+
+But when I loaded in the vinylcutter I did not like the way the eyes came out.
+
+ 
+
+So i went back and found another images, used the line art trace (on the right below) and thought this is
+a better option to go with:
+
+ 
+
+
+I loaded this in to my vinyl cutter software and it did a nice job breaking all the colors apart
+
+
+
+
+After removing a few parts I got to something I liked
+
+
+
+But there are too many colors
+
+
+
+
+and so i used the layers to consolidate to 3 colors
+
+
+
+Now lets get cutting!!
+
+
+
+That DID NOT WORK out at all!!
