The MSYS Command `[MLEPC]`

The MSYS command is used to specify a machine coordinate frame for subsequent CL data. The MSYS command is informational, unless a form of automatic LCS is enabled based on the MSYS command definition. This command is valid for all machines.

$\textbf{MSYS}\;\textbf{/}\;\bigl[\,\textbf{LAST},\bigr]\,\mathtt{<\!matrix\!>}$

Two separate coordinate frames can be defined. MSYS defines the primary coordinate frame and MSYS/LAST defines a second coordinate frame.

The <matrix> typically defines the location and orientation of the machine coordinate frame with respect to the part coordinate system. The matrix can be specified using the standard post-processor transformation syntax (see “The ORIGIN Command [MLEPC]”).

A coordinate frame defined by MSYS can be subsequently referenced by any of the post-processor commands that support a transformation capability. These include LCS, LIMIT, PLOT and ORIGIN. With the exception of the LCS/AUTO command (see here), the MSYS frame definition is informational. The updated frame definition only takes effect when one of these other transformation commands is next coded. For example:

MSYS/*matrix1*
GOTO/…            $$ no frame in effect
LCS/MSYS
GOTO/…            $$ *matrix1* in effect
MSYS/*matrix2*
GOTO/…            $$ *matrix1* still in effect
LCS/MSYS
GOTO/…            $$ *matrix2* in effect

When LCS/AUTO,3 or LCS/AUTO,4 is active, the MSYS command defines the new local coordinate system, which is applied immediately. For example:

MSYS/*matrix1*
GOTO/…            $$ no frame in effect
LCS/AUTO,3
GOTO/…            $$ *matrix1* in effect
MSYS/*matrix2*
GOTO/…            $$ *matrix2* in effect
