Stop
Touch the Stop button to halt axis motion.
CAUTION
The Stop button is not intended as a substitute for hard-contact emergency stop
switches. Touching the Stop button is a convenient way to halt axis motion, but do
not rely completely on this software interface - always be prepared to use the emer-
gency stop button to halt motion.
Random
Touch the Random button to initiate a final extended series of vector moves involving all axes. The stage
will be moved random distances in random vector directions within the test volume defined by the Test
distance values.
In this example, combined X, Y and Z axis vector moves
will be made randomly inside a 20mm X 10mm X 10mm
rectangular space. Moves will continue until the Stop
button is touched or the system detects a following er-
ror higher than the Max following error specified in the
CNC Setup screen.
