3. External - without calculation
This method is performed in the same way as calculation to end
point, except that subroutines called via EXTCALL are skipped in
the calculation. In the same way, with G code programs that are
executed entirely by external drives (disk drive/network drive),
calculation is skipped until the target block is reached.
This helps to speed up the calculation process.
Notice
Modal functions included in the part of the program that is not
calculated are not taken into account for the part of the program to be
executed. In other words, with the "Without calculation" and "External
– without calculation" methods, you should choose a target block after
which all the information needed for machining is included.
With the "Other ShopMill block or G code block" target type, you can
enter the target directly in the "Search pointer" screen form.
Each line of the screen form represents one program level. The actual
number of levels in the program depends on the nesting depth of the
program. Level 1 always corresponds to the main program and all
other levels correspond to subroutines.
You must enter the target in the line of the screen form corresponding
to the program level in which the target is located. For example, if the
target is located in the subroutine called directly from the main
program, you must enter the target in program level 2.
The specified target must always be unambiguous. This means for
example that if the subroutine is called in the main program in two
different places, you must also specify a target in program level 1
(main program).
The parameters in the "Search pointer" screen form have the
following meaning:
Number of program level
Program: Subroutine is in NC working memory
Program name
Example: subrt1
Subroutine is not in NC working memory
Path + program level
Example: c:\subrt1 or
\\r1638\shopmill\subrt1
(the name of the main program is automatically
entered.)
Ext: File extension
P: Continuous counter (if part of a program is repeated
several times, you can specify the repetition number
at which you wish machining to be resumed.)
