Example 1
Specify the center of a circle and circular interpolation in absolute mode
Current position (4000, 2000), axis parameters: default values, the G codes to be executed are:
N0 G90
N1 G17
N2 G3 X1000 Y3000 I-2000 J-1000
After G codes are executed, the Y/X curve for the whole movement process is shown below:
