3.1. G92 reference point setting
When setting program running, the coordinates of processing start (reference point) must be put at the start of
the program.
Format: G92 X0 Y0
If G92 isn’t followed by X, Y, the current coordinates of X, Y will be the reference point. Generally, if the
origin of machine tool is used for positioning, G92 won’t be followed by X, Y.
3.2. G21/G20 metric/imperial system setting
Set the length unit (default: metric) of program processing
G20: imperial (unit: inch)
G21: metric (unit: mm)
Format: G21
This instruction sets the length unit (mm) of processing. It is usually written in the second line of the program
(unless temporary change is required), i.e. next line of G92. The instruction isn’t followed by any content, and
will persist until next G20 or G21.
3.3. G00 space shift
This instruction can return the torch to specified position quickly, and the system moves from start to end in linear.
The processing is at run idle speed, i.e. maximum manual speed, and isn’t controlled by percentage.
Format: G00 Xn Yn
For example: G92 X0 Y0
G00 X75 Y75
M02
Current position of torch
Expected position of torch
3.4. G01 straight line cutting
This instruction can feed the torch to specified position in linear and single axis or two axes linear interpolation is
allowed as cutting instruction.
Format: G01 Xn Yn
