Week 3 - Computer Controlled Cutting : Local Session#

Agenda#

characterize your lasercutter’s focus, power, speed, rate, kerf, joint clearance, and types
Document your work to the group work page and reflect on your individual page what you learned

Cut something on the vinylcutter
Design, lasercut, and document a parametric press-fit construction kit,
- accounting for the lasercutter kerf,
- which can be assembled in multiple ways,
- and for extra credit include elements that aren’t flat

Group assignments：
- characterize your lab lasercutter’s focus, power, speed, rate, kerf, and joint clearance
- Examples：Kamakura 2020, 2021, 2022 Kuriyama, 2022 Indonesia
Individual assignments：
- Make Pressfit Construction kit
  - What is “pressfit”?
  - Understanding “parametric design”
  - What to set as parameters?
  - Make sure it can be assembled in different ways!
- Use vinyl cutting machine to make something

Each lab should have at least 1 group assignment documentation (and show all student participated).
You can make more than 2 groups and document seperately.
IMPORTANT : Cite each week’s group assginment page in your individual Weekly Assignment Page.
【超重要】各々個人ページからグループページへのリンクをはること!

Method 1: Commit directly to the main branch
Same process as you upload your indivisual documentation.
Always make sure to pull remote and get the latest version before you edit.
You will encounter conflict if you edit the same line at the same time.

個人ページを更新するときと同じ手順です。編集する前に必ずPullしてください。同時に同じファイルの同じ行を編集するとコンフリクトが発生するの注意してください。

Method 2: Branch out and send merge request
Effective way to keep track and organize when you’re working in a large group.
Reference : GitLab CE Tutorial #6 - Merge Requests
参考：Git Labでマージリクエスト（プルリクエスト）をするまで

Git Merger Procedure

Procedure
- A leader creates assignment page and decide the section each student is in charge of
  まずはマージ役の人が、課題ページのmdフアイルに、各自の担当セクション部分を見出しで追記
- Each student creates working branch (have shared branch nameing rule)
  各自それぞれブランチを切るブランチ名は共通の命名規則を作っておいたほうがいいです。
- Each student commits to one’s branch
  各セッションの参加者がそれぞれのブランチへcommitする
- Send merge request to a leader when it’s done
  各週ドキュメントが終了したら、マージリクエストを送信する
- A leader checks merge requests and merge them to master branch
  マージ役が確認 / masterブランチへマージする。
Note
- Better not to make change on other student’s line to avoid unnecesarry conflict when merging.
  グループページのMarkdownファイルを編集する際に、自分以外の人のセクションのところを編集しないようにしてください。編集の衝突（Conflict）が発生してmergeができなくなります。
- 参考：gitで同一ファイルを複数人で編集した場合の衝突

Check parameter, kerf width (spot diameter), precision and limitation of the laser-cutter in our lab.

The Evaluation Process (“Nueval”) is now active. Go to https://nueval.fabacademy.org/, and log in with your FabClout account.

The evaluation process:

Students completes Weekly Assignment
Students checks Checkboxes at Nueaval to indicate that the Local Evaluator can start.
Local Evalutor evaluates and gives feedback.
If the Local Evalutor suggests improvements, GOTO 1.
If the Local Evaluation is at 100%, if will be handed off to an anoymous Global Evaluator
Global Evaluator evaluates and gives feedback.
If the Global Evalutor suggests improvements, GOTO 1.
If all your Documentation is at 100% you have finished FabAcademy! Congratulations!
Well, not quite. You still need to present in front of Neil and your Peers.

Overall Progress of Nueval.
