ADJUSTMENTS AND SETTINGS
WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN WORKING IN
THE TOOLING AREA OF THE MACHINE TO AVOID INJURY. THE FOILS ON THE
FRONT AND REAR BOARD CLAMPS ARE VERY SHARP.
WARNING
COMPRESSED AIR. COMPRESSED AIR SHOULD NEVER IMPINGE UPON THE
BODY. PORTS, PIPES, ETC MUST NEVER BE BLOCKED BY HAND. BEFORE
CONNECTING OR DISCONNECTING ANY PNEUMATIC COMPONENTS, ENSURE
THE COMPRESSED AIR SUPPLY HAS BEEN DISSIPATED AND DISCONNECTED
FROM THE MACHINE.
CAUTION
EQUIPMENT SERVICING. THE LASER DOES NOT CONTAIN USER
SERVICEABLE PARTS. OPENING THE UNIT COULD CAUSE MIS-ALIGNMENT
OF THE LASER, THIS MAY MAKE THE EQUIPMENT DANGEROUS TO OPERATE.
CAUTION
RADIATION. RISK OF INJURY TO THE EYES DUE TO LASER LIGHT BEING
PRESENT IN THE VICINITY OF THE LABEL. DO NOT LOOK AT THE LIGHT
SOURCE OR REFLECTIONS FROM A SURFACE.
WARNING
HARMFUL SUBSTANCES. CLEANING WIPES AND CLEANING SOLUTIONS MAY
CONTAIN SUBSTANCES HAZARDOUS TO HEALTH. WHEN USING CLEANING
WIPES AND CLEANING SOLUTIONS THE MANUFACTURERS’ SAFETY DATA
SHEETS MUST BE STRICTLY ADHERED TO.
MANDATORY
TOXIC CHEMICALS MAY BE PRESENT. SAFETY GLOVES MUST BE WORN.

Idle height is the position to which the needle tip is set, between dispensing
actions. The dispenser moves to its dispense site, after dispensing it is moved
to the idle position, before moving on to the next location. There are two
procedures:
• Manual
• Automatic

Stinger Heights
(Manual)
This procedure relates to units that:
• Do not have the automatic calibration option
• Have had a hardware change
• Are being set up for the first time
• Have undergone a product changeover
The height calibrations are a reference for all programmed deposits. For non-
automatic calibration units, two heights are set: Contact Height and Idle Height.
Idle height tracks the contact height automatically.
The Z-Axis contact position, for any product, must be within (+/-1mm (manual)
+/-1.5mm(automatic)) of the calibrated contact position. If the contact position
cannot be guaranteed to be within these limits, there is a likelihood that a
variation in dot size may occur and deposit quality degraded.
Contact Height Contact height sets the laser to needle height in relation to the upper surface of
the product. A relative measurement is made for all other programmed loca-
tions.
1. Open the printhead front cover.
2. Remove the screen.
3. Close the printhead front cover.
4. Select Setup Product.
5. Select Setup Options.
6. Select Stinger Dispenser.
7. Select Load Board and load a product.
8. Select Stinger Heights to open the stinger heights calibration page.
9. The camera axis moves the stinger unit to the centre of board location by
default, however, this position can be set to any location using the Calibra-
tion Point X / Calibration Point Y parameter pair. See information on
placing the calibration point, later in this manual.
10. Select Stinger Jog Mode and initially set the mode to Coarse (1 step =
0.5mm).

11. Open the printhead cover.
12. Select Step Up or Step Down to move the nozzle into position just above
the board.
13. Place the 0.05mm feeler gauge on the board directly below the nozzle tip.
14. Select Stinger Jog Mode and set the mode to Fine (1 step = 0.05mm).
15. Continue jogging down until the feeler gauge has a small amount of resist-
ance to being pulled from under the nozzle tip. Do not jog down beyond this
point; any deflection of the board results in poor output and must be avoided.
The feeler gauge and the nozzle should not deflect the product down. Any
movement of the product away from the nozzle tip causes a discrepancy in
the laser reading.
16. Select Save Contact.
17. Select Back.
18. The camera axis moves the unit to the right hand edge of the board. This is
the Range Position where the unit performs a Range Check.
19. The nozzle moves down from contact height, either 1mm or 1.5mm depend-
ent upon which stinger option is fitted.
20. The nozzle moves up through contact height to 1mm or 1.5mm above
contact height. This completes the Range Check.
Board Clamps may cause boards to bow slightly in the centre.
This may cause the measurement to fall outside the 0.1mm
minimum Z Axis contact position.
The feeler gauge thickness is the equivalent of one step of
the Z Axis stepper motor. It is essential that when
setting this
contact point no board deflection occurs.
