If G04 isn’t followed by Ln, the system will be delayed without day after executing G04 until you press [Start] to
stop the delay.
3.7. G26, G27, G28 returning to reference point
This instruction can return the torch to reference point automatically. The processing is at run idle speed, i.e.
maximum manual speed, and isn’t controlled by percentage.
Format:
G26 X axis returns to reference point
G27 Y axis returns to reference point
G28 X and Y axes return to reference point
For example: G28 (X, Y axes return to reference point at the same time, which is like G00)
3.8. G22/G80 circular processing
This instruction is used for cycle processing, and G22 is the start of cycle and specifies cycle times L. G80 is the
end of cycle. G22 and latest G80 downwards constitute a cycle.
Format: G22 Ln_ (L specified cycle times)
Cycle
G80 (cycle ends)
For example: 0000 G92 X100 Y100
0001: G22 L10000 ——cycle starts
0002: G00 X50 Y50
0003: G01 X80 Y80
0004: G80 ——cycle ends
0005: M02
3.9. G81 workpiece counting
This instruction is the total workpieces memorized and processed by the system automatically.
Format: G81
For example: 0000 G92 X0 Y0
0001: G22 L3——cycle starts
0002: G01 X50 Y50
0003: G81——Count
0004: G80——cycle ends
