CNC Setup
Warn users on first CNC movements
Users can be warned of first CNC movements as a means of avoiding collisions. Enabling this warning
is strongly recommended. To enable the warning, Check the
Warn user on the first CNC movement box.
Disable following errors during startup
When auto homing is used during startup, the CNC homing sequence moves the stage to read encoder ref-
erence marks and determine machine zero. Following errors developed during the homing sequence can be
large enough to cause error messages to be displayed under typical operating conditions. However, these
messages would have little meaning during the homing sequence and can be disabled as a convenience to
the user. Check the Disable following errors during startup
box to suppress following error messages during the homing
sequence.
Inhibit delay
Normally, the CNC amplifier responds immediately to high and low level transitions on its inhibit control
line. However, a delay can be applied to motor drive outputs to accommodate special hardware require-
ments. Enter the inhibit control delay into the Inhibit delay data field in mil-
liseconds.
Continuation zone debounce time
When a CNC move crosses into the target’s continuation zone, a debounce time is initiated to eliminate
indecision at the continuation zone boundary. The move is not complete until the final position remains
inside the continuation zone for the duration of the debounce time. Enter the debounce time into the Con-
tinuation debounce time data field in seconds.
Continuation zone timeout
When a CNC move crosses into the target’s continuation zone and stops, a timeout is initiated to notify the
user if the probe should fail to fire. Enter the continuation zone timeout into the Continuation zone timeout
data field in seconds.
NOTE
The continuation zone timeout must be longer than the delay in firing after
CNC movement described later in Specifying a probe firing delay on the next page.
