There are some hidden commands that can be inserted into the START of conversion, END of conversion and PRE-CONVERSION user options. Using pre-defined macro command codes users can :
•Split lines at user defined positions using the ^ key.
•Replace a program word or letter address using the * and $ keys.
•Delete an entire line using the ~ key.
Examples are below.
SPLITTING LINES at a user defined position.
This option is available in START of conversion, END of conversion and PRE-CONVERSION options.
Original Command : G00G91G28Z0M09
Replacement Command : G00G91G28Z0^M09

(1) One-For-One Replacement
In the following example G43 is defined as the trigger to look for using the * to end the definition of the trigger.
Once the trigger is found, search the line for whatever follows the trigger ( in this case H ) and replace it with replacement command definition.
The following applies to CNC XChange Version prior to 20.0.0.
Original Command : G43*H
Replacement Command : HA
Result :
G43Z20.000H01M08

G43Z20.000HA01M18
The following applies to CNC XChange Version 20.0.0 and higher.
In the following example G43 is defined as the trigger to look for using the * to end the definition of the trigger. Other individual conversions the user desired to be executed on the line containing the trigger can then be defined ... each separated by the * character. Make certain that the correct order for original and replacement are maintained.
Original Command : G43*H*M08*
Replacement Command : G43*HA*M18*
Result :
G43Z20.000H01M08
