F4 (Setup Menu)
Below is a list of functions, which are found under the
F4 (Setup)
key. These functions are
all related to the setup of dispensing parameters.
5.1
Line Speed
Registers the line speed used for all lines from the current memory address forward until
another Line Speed instruction is found.
5.2
Line Dispense Setup
When dispensing high viscosity materials, there is often a delay from the moment the
dispenser is turned on until the material begins to flow. The following parameters are set
under this function: Head Time, Tail Time, Node Time and Tail Length.
The
Head Time
setting is a delay time used at the start of line dispensing to prevent the
tip from moving along the line path until the material is flowing. The tip will move to the
start of the line, turn on the dispenser and wait for the time period specified in the
head
time
setting before moving. The time value can be adjusted to ensure that the material
begins flowing at the same time as the line movement begins.
At the end of dispensing, a delay is often required after the dispenser is turned off, to allow
the barrel pressure to equalize, before moving to the next point location. This prevents
material from being „spilled‟ where it is not wanted. This time delay at the end of
dispensing is called the
Tail Time
.
The
Node Time
parameter enters a wait time that only affects the
Line Passing
command. Tip will pass through line passing point and will wait at line passing point with
the dispenser activated for the time specified in the
Node Time
.
Usually the material continues flowing after the dispenser is off, due to pressure built in
the system.
Tail Length
automatically turns off the dispenser at a user defined distance
before the end of a line, preventing excess of material to be deposited at the end of the
line.
