Ctrl Command set_matrix
Function
sets the coefficients of the general transformation matrix M
T
for all subsequent coordinate
transformations (see "Coordinate Transformations", page 161).
Call set_matrix( HeadNo, M11, M12, M21, M22, at_once )
Parameters HeadNo Number of the scan head connector as an unsigned 32-bit value:
= 1: The definition only affects the primary scan head connector.
= 2: The definition only affects the secondary scan head connector
(activation required)
= 0, 3: The definition affects both scan head connectors.
= 4: The definition affects the virtual image field (also see comments)
Only the three least significant bits are evaluated.
M11, M12,
M21, M22
Matrix coefficients of the general transformation matrix M
T
as 64-bit IEEE floating point values; allowed range: [–50 … +50];
if the parameter is set to an invalid value, the command will be ignored.
at_once This parameter (unsigned 32-bit value) determines when the defined
transformation becomes effective:
= 0: The new total transformation (total matrix and offset) is only
calculated and applied to the current position when the next list
command is executed.
= 1: The new total transformation is calculated immediately (or before the
next list command if a list is currently BUSY or the board is INTERNAL-
BUSY) and applied to the current position. The “laser active”
laser control signals will first be switched off if necessary.
= 2: The new total transformation (total matrix and offset) is only
calculated and applied to the current position when the next
jump_abs, jump_rel, goto_xy or goto_xyz command is executed.
= 3: As with
at_once = 1, but the laser control signals remain unaffected.
> 3: See
at_once =2
Comments • See "Coordinate Transformations", page 161.
• The coordinate transformation defined by
HeadNo = 4 is only in effect during a
Processing-on-the-fly application initiated via set_fly_2d (see the section "Coordinate
Transformations in the Virtual Image Field" on page 185). Here, the
at_once parameter
is ignored.

5 unchanged primary functionality (matrix definition), however:
• The parameters
HeadNo and at_once are new.
• Reduced value range for coefficients.
• Also see "Notes for RTC
