List Command
arc_rel_3d
Function
moves the laser focus at marking speed from the current position spirally around an axis
parallel to the Z axis. The x and y components thereby characterize an arc with the
specified angle around the specified axis, while the z component characterizes a linear
motion from the current position to the specified end point. The position of the spiral axis
and the z end coordinate are specifiable as relative coordinate values.
Restriction
If the 3D option is not enabled or no 3D correction table has been assigned (see
), then the command will have the same effect as
.
Call
arc_rel_3d( dX, dY, dZ, Angle )
Parameters
dX, dY
Position of the spiral axis (parallel to the Z axis) as relative coordinates in
bits
(signed 32-bit values);
allowed range: [–8388608 … 8388607]; out-of-range values will be edge-
clipped. The complete value range [–8388608 … 8388607] is only usable as
a virtual image field e.g. for (enabled) Processing-on-the-fly applications. The
current coordinates will be clipped to [–524288 … 524287] (real image field
size) during runtime directly prior to use of the correction table.
dZ
relative Z end coordinate in
bits
as signed 32-bit values;
allowed range: [–32768 … 32767];
(an out-of-range value will be edge-clipped).
Angle
arc angle in ° as a 64-bit IEEE floating point value
(positive angle values correspond to clockwise angles);
allowed range: [–3600.0° … +3600.0°] (±10 full circles);
an out-of-range value will be edge-clipped.
Comments
• The position of the spiral axis (
dX, dY
) and the Z end coordinate (
dZ
) are to be supplied
as relative coordinates with respect to the current position. Otherwise, the command is
identical to
(see the comments there).
