3.5 Jet Setting from the Front Panel (Continued)
Refill (msec): Refill time is the time required for the material to flow into the nozzle after
each drop is ejected. Refill is set in msec with 0.1 msec resolution. Section 6.1 - Timing
Recipe Parameters provides a detailed explanation of Refill Time.
Dwell (msec): Dwell time is the time required for the material to flow out of the nozzle
and form a drop. Dwell is set in msec with 0.1 msec resolution. Section 6.1 - Timing
Recipe Parameters provides a detailed explanation of Dwell Time.
Refill+ (msec): Sometimes the jet requires a little extra time for the first drop to be
ejected, depending on the material or if the jet is idle for a period of time. Refill+ time is
added to Refill time to adjust the size and quality of the first drop. In PULSE mode,
Refill+ time applies to each drop; in LEVEL mode, Refill+ time applies to just the first
drop. Detailed explanations can be found in Section 6.2 – Programming Timing Recipes
(Adjust Refill Time for First Drop), and also Appendix 1: First Drop Compensation.
Drops: Specify the number of drops to be dispensed. To dispense a single drop per
trigger signal, enter 1. To dispense 10 drops per trigger signal, enter 10.
Note: If the Advanjet controller software is being used and values are changed using
the front panel display, the changes will not be transferred to the Advanjet controller
software. Also, the front panel values can be overwritten each time you start the
Advanjet software program. The warning below will be displayed. It is recommended to
write down any recipe changes made from the front panel and then enter them into the
software to synchronize.
