Initials Lab

Outcomes: The purpose of this lab is to demonstrate student understanding of general G Code syntax, absolute coordinate mode, and G02/G03 arc programming using both IJK and R methods.

Instructions: Write a program that uses a felt-tipped pen to draw your initials (two or three letters)

  • Bounding box is 6 inches wide by 5 inches tall
  • Z-Zero is the drawing position.
  • You must use arcs in both letters. Minimum three arcs. Must include a G02 and G03.
  • The origin (as indicated in the header file) is located in the exact center of the 6×5 bounding box.
  • Your initials must be centered in the bounding box.
  • NOTE: The origin is not up to you. It is the center of the rectangle. You will have positive and negative XY values.
  • NO ramping.
  • Your program MUST have at least one each of R style and IJK style arcs.
  • Your program MUST have at least one G02 and one G03
  • Use notepad or a similar ASCII editor program (not a word processor).
  • Use the header file on the “All Labs – Common Setup Files” page.

Use NCviewer to check your code for possible errors.  Note that NC viewer is much kinder to your syntax than the controller will be.
