Taking a Point and than setting connection and commands





You can set formula and its value by connecting them to one another




Now as taking ahed you can joint to diffent values and commands with refrence and connecting them to make a final output

Some Quick Points

  • Keep MDF sheets on Plain surface , bend in sheet create probelm in cutting .
  • Test material once with small circle of 5 mm diameter so you would have perfect power , speed and frequency its helps a lot in get job done in one go and save material wasting while prototyping.
  • Few adjustment on Rhino may help you to save time in cutting. example joining line which can overlaped in design so it cut on single go.
  • Use vernier for presicion of size if you are going mount components on it.
  • Practising with design in laser cutting you can also try for saving material which can be used for other small projects later.
  • In vinyl cutting low gum tape is used but for small cuts u need to b very precise it can spoil your design.
  • Frame for T- Shirt Printing should be clean properly, moisture in frame makes airpokect and it may spoil prinitng
