14.10.1 Variables only used during block preparation
The CNC reads several blocks ahead of the one being executed in order to calculate in advance
the path to follow.
As can be seen in the following example, the block being prepared is calculated with the tool T6;
whereas the tool T1 is the one currently selected.
There are specific variables for consulting and/or modifying the values being used in the
preparation.
They can only be accessed from the program (PRG) and they are evaluated during block
preparation.
When writing in any of these variables, the table is not modified; the new value is only assumed
for block preparation.
The following table refers to the tool being prepared, unless stated otherwise.
G1 X100 F200 T1 M6 (Block in execution)
Y200
G1 X20 F300 T6 M6
X30 Y60 (Block being prepared)
