Mark Delay
Although the marking speed is usually lower than
the jump speed, a lag between the set position and
the real position occurs not only during a jump, but
also during a mark or arc command.
To make sure that the scanners reach the final
set position properly before the next command
starts, the RTC
®
4 inserts a
mark delay
after a single
mark or arc command or after the last mark or arc
command of a polyline – also see
.
Notes
• If a mark or arc command is followed by a zero
jump, mark or arc command, then the MarkDelay
is
not
executed.
• If a jump vector is followed by a zero jump vector,
then the first JumpDelay is not executed.
In contrast, the JumpDelay
is
executed if the jump
vector is followed by a zero mark or arc
command.
