Rubber Scratch Force
displays and sets the down force used during tangential emulation.
This is primarily used when cutting thick materials such as sandblast rubber. Tangential emulation
simulates a tangential or servo controlled rotating knife by moving to a position short of the vector
to be cut and putting the knife blade down with a very light force while moving toward the
direction of cut to align the knife before applying the full cutting force. This improves the cut
quality in thick materials. (default 0.1%).
Rubber Backup Multiplier
(default 20) displays and sets the distance the knife will be dragged
at the light force used to align it. This parameter is used with and is additive to the
Rubber
Backup Offset
(default 0.001)
. The Rubber Backup Multiplier is based on the change of angle
between vectors and the Rubber Backup Offset is a constant added to the distance calculated based
on angle. Amount of backup to align knife is angle between vectors in radians * mult
offset.
Max Motion Vector Length
(default 0.001) (Named after the driver that outputs very small
vectors) Allen Cutters very accurately replicate the vectors in the HPGL plot file. Some design
programs output vectors that are very short. It is sometimes desirable to combine some of these
vectors into a longer vector to eliminate jagged edges or slow cutting. This parameter works like a
curve-smoothing algorithm and is used to improve poor HPGL files.
Anticipation Rubber
(
default 0.001)
and Anticipation Vinyl
(default 0.0004) is a parameter
that adjusts the backlash compensation in the cutter. The Anticipation Rubber is the parameter
used when the cutter is in tangential emulation mode and the Anticipation Vinyl is the parameter
used when not in tangential emulation mode. Heavier materials require more backlash
compensation. These numbers are individually set at the factory and should not require adjustment
except when cutting heavy materials. If you are experiencing thick and thin lines or misshaped
letters, adjust the anticipation parameter to obtain satisfactory results.
Line Sensor
Clicking on Setup Line Sensor menu opens the SmartMark
TM
Menu.
Sensor Offsets
- The SmartMark
sensor is offset from the center of the
knife. The sensor offset distance is
preset at the factory or during
installation, but may need to be
adjusted on occasion. The i-TECH can
automatically calculate and set the
SmartMark
offset and sensor size
parameters. See drawing for definition
of sensor offsets. Title: Calibration
Sensor size
is the offset from the
exact center of the red dot of the
SmartMark
sensor to the sense radius
and may change based on sensor
sensitivity or media reflectivity. This
parameter is best set using the
procedure in the above TSB. The
Sensor Size parameter is only useful in origin
scale and three target scanning. If you are not,
