Group Project/Project Management/Parametric Cadding/Vinylcutter

Group Project

There were two parts to the group assignment

1. Find the power level - this took many tries and moving the speed by 1% made very marginal changes so took a while to get from 35% to 23% which was the final answer for.15 in cardboard with no bowing. Due to some variation in the cardboard though it was just easier to set to 15% and do two passes if the wood was bowed to get a clean cut.
2. Finding the kerf - this was a lot easier and I just had to measure the width of the cut with the caliper and then divide by 2 which ended up being .5mm or .02 inches

Project Management

I went through:

1. Github intro and essentials article - practical command line things to track
2. Github top 7 tips - there is an autocorrect feature that is very helpful
3. Read through a github project that has all sorts of tips grouped together which I found to be the most helpful because of how in depth it is for exmaple:
   1. git update-ref -d HEAD - this is a command that deletes the last commit
   2. git branch --merged master - this is a command that shows all the branches that have been merged into master
   3. git branch -vv - this is a command that shows all the branches and their upstreams

Parametric Cadding

1. First talked through the considerations needed for cadding something parametric and dynamic with TAs. Learned how to use variables in measurments for example keeping the kerf handy is good. Not sure how to join the pieces together so I need to go to OH
2. Spent a lot of time trying to get kerf right and realized that my slot and tab were not the same size when I scaled so kerf was never really implemented making press fit not work. I added a specific tolerance to the slot in order to tune the fit. Also learned how to arrange pieces in fusion and project onto a sketch making the workflow faster. Lastly, got more familiar with the version control on fusion.
3. Got the the press fit to work after adjusting the tolerance a couple times.Once I got the write tolerance I added a Chafer to the box to have it fit in place better. Ran out of time to spiral to something bigger but learned many lessons in cad and laser cutting. Towards the end I was able to iterate faster on the laser cutting and cadding and version control which will flow into future projects.

Vinylcutter

Followed the tutorial that Anthony and Maya gave on how to use the vinylcutter and pretty easily got a sticker out. It now makes a lot of sense why you dont want complicated stickers or you will be there for a while. If it doesn't stick the first time keeping fighting champ.
