4.12 Needle Finder Configuration
Needle-type nozzles are easily damaged or frequently changed. The Needle Finder option locates the
current location of the needle tip, compares the current location with the last measured location, and
adjusts the tool offset to maintain consistent dispensing results, prevent quality problems, and
reduce scrap.
The needle finder support in ECXP includes two programming instructions, Find Needle and Check
Needle. The instructions are located on the Needle Finder tab, which only appears when the system is
configured for a needle finder. For additional information, see Section 5 - Programming.
 NOTE This procedure should be done on initial setup and whenever there is a change in the
board stop location or fixed conveyor rail position, or if the needle finder is moved.
