 **Accomplishments**
  
+We completed the **group exercise** characterizing our lasercutter [Here](insertlink). 
+
+Here are my top 5 insights:
+
+1. The kerf is not consistent and dependent on the material to some extent 
+2. The impact of 1% change in speed is a multiple of the same % change in power 
+3. It is very important tol keep clean laser lenses and mirrors clean  
+
+The **Parametric kit** design was a great way to "burn in" some of the new learning from CAD week. I 
+made a mistake with the slot width which I only discoverd after my first cut and so came to 
+appreciate the speed of the change possible in a parametric design.
+
+User testing is alway critical!!
+
+I came to appreciate the vinyl cutter. I think this **Sticker** just scratch the surface but I am 
+looking forward to seeing what else this little machine can do. It was clear to me as a novice that
+choosing the right image to start with is critical to success and ease of the process

  ## Parametric construction kit 
 
 I decided to use Cuttle for this effort and like the idea of leveraging the number of sides as a key

 That DID NOT WORK out at all!!
+
+I did some investigation and looks like a number of issues:
+
+1. Picture very complicated with lot of cuts even in areas with the same color 
+
+2. I was using too much cutting pressure
+
+I went back and got another version of the picture that is line based 
+
+![New pic](../images/ImagW3/Sticker/9simplealbert.jpg)
+
+I then used the "weld" feature to combine areas of the same color and avoid unnecessary cuts
