Ctrl Command goto_xy
Function direct jump to the specified position
Parameters
xpos, ypos
Integration Pascal:
C:
Basic:
Comments • With DSP program files RTC4D2.HEX / RTC4D3.HEX, version 2.417 / 3.417 or higher the
jump speed is set with the commandl
program file versions, a
50000 bits / ms.
• Usually scan systems are optimized for scanning vectors (not for jumps). Therefore,
after executing a jump via the
shoot may occur. Then – depending on the jump distance – the set positions may be
reached only after a longer settling time. Therefore an appropriate low jump speed
should be previously set via the
RTC4D2.HEX / RTC4D3.HEX, version 2.416 / 3.416 or lower the jump speed is always set
to maximum value of 50000 bits / ms, jumps should be realized via the list commands
jump_abs
• The command will be ignored if a list is executing at the moment.
• Image field correction will be applied.
• If an image transformation is defined with the commands
it will be applied.

Ctrl Command home_position
Function activates the home jump mode and defines the home position
Parameters
xhome,
yhome
Integration Pascal:
C:
Basic:
Comments • This command is intended for a laser system that does not allow fast switching of the
laser. After calling the command, the laser focus moves to the specified home position
whenever no list is executing.
• At the beginning of the next list, the laser focus automatically jumps to the start point
of the first list vector. The RTC
• A beam dump should be placed in the home position.
• The home jump mode is deactivated with the command home_position(0, 0).
