NOTE: Always perform this operation as follows:
G41 / G42: Cutter Radius Compensation
Because the laser beam has a discernible diameter it will create a "kerf" or cutting path which has
some measurable width. In order to control the tolerance of a part, cutter compensation can be activated to shift the
cutting path to the left or right of its programmed path. Depending on the direction of travel
(clockwise/counterclockwise ) and the nature of the cut (internal hole/perimeter) either G41 or G42 are selected to
shift the cutting path. The amount of the shift is determined by a "D" value which is entered in the following manner:
EXAMPLE:
- Cutter compensation must be activated on a G01 line and should be done so on a lead-in before
the part geometry is cut.
- Cutter compensation must be canceled before the next positioning move is performed.
- Cutter compensation can be canceled by:
1. Pressing "RESET"
2. Executing an M02 or M30 command.
3. Executing a cutter compensation cancel command ( G40 ) * This is the standard method
- The amount of cutter compensation can be set programmably with a G10D__R__; command
which will override the parameter setting for the "D" value.
G91G28Z0.0; Incrementally raise the Z axis so that it is clear of any tipped parts.
G28X0.0Y0.0; Once the Z axis is clear, the X and Y can be moved.
