Z - AXIS
Servo Motor Design
New Linear Bearing Design
Hollow Core Servo Motor
Direct Drive Lead Screw
Maximum resolution and stiffness during movement for improved Snap-Off
Z+Theta SERVO MOTORS
Both the Z and Theta use Resolver feedback.
Both Servos need Step and Direction signals to work. The Theta motor needs a Positive signal to enable and the Z motor needs a Negative signal to enable.
The servos have a digital display letting you know the condition of the servo:
1. On the Z motor servo a dash (-) indicates that it is OK.
2. On the Theta motor servo a Zero (0) and a period (.) indicates that it is OK.
Direction signal for the theta axis only is a differential signal. For this reason Motion Multiplex (mux) #3 is different from the others and no longer interchangeable with the other mux cards.
Snugger system uses two pistons at ends of bar
Results in more flexible and repeatable board handling
Snugger Height - Four Inter-Dependent Fine Pitch Motors
(the eccentrics are no longer used for snugger height)
New Flipper Design
Handles difficult boards
Vacuum Shut off
Immediately shuts off vacuum for better stencil release.
Results in more flexible and repeatable board handling
1. They ride on a four bar linkage.
2. Can be changed to a thinner flipper, 0.005 (5mil) so you can print
with the flippers on. (Not available at this time)
3. There are 2 pistons for extending and one for retracting (retract piston
is spring loaded).
4. Pistons have a Lip seal that go into the piston block.
Note: Prior to disassembly Shut down the air, if done with the air on,
pistons will go flying.

BOARD THICKNESS AXIS
Calibrating Snugger Height
1) Calibrating the BD_THICK sensor.
**This sensor is used as a mid type sensor. During reset the BD_THICK Screw comes out of the screw housing until the sensor is turned on then it travels inward.(Negative) -0.270 inches--- This is the Negative software limit. If the sensor is set incorrectly it will bind at this point. Then when it steps off to its default value the motor screw will move off at different setting depending on how much it was bound up during over-travel.
1. In axis base settings with the Z-axis at board transport height Jog the BD_THICK axis negative until the motor stops turning.
2. Slowly jog the axis positive ( Move Upward ) until the knob on top of the motor just starts to move about 1/8 to 1/4 of a turn.
3. Hit exit on the mouse then select "RESET AXIS" on the axis base setting screen. This will reset the counter on the BD_THICK axis.
4. Jog the BD_THICK axis to 0.280 and set the BD_THICK Sensor to "Just off".
5. Next jog the axis positive to 0.290 the SENSOR should turn on before it gets to 0.290
6. Finally slowly jog the z axis up and verify that the striker plate will not contact the BD_THICK SENSOR. If it does the sensor will have to be reset (redo procedure)
NOTE: After calibrating the BD_THICK sensor the motors will have to be retimed and snugger height will have to be redone.
Also after calibrating snugger height the machine MUST be powered down before verify
2) Timing the board thickness motors.
1. Always check snugger height with the table at vision height. At snugger height eccentrics may be touching. The newest software allows the snugger height to be checked at snugger height but it is best to verify at vision height.
2. Turn off Stepper Power 2 through the I/O screen.
3. Measurement should be with Z-track on. Make your measurement at the end of the rails.
4. Your reference will be on the left front adjustment (This is your reference adjustment, DO NOT TOUCH.) The three other points where you’ve made adjustments should be within 0.001 mil.
7. Of the three adjustments, two have the thumbscrew adjustments on top, the right rear the adjustment is on the bottom.
8. Turn Stepper Power 2 back on and Reset the machine.
3) Perform the Calibrate Snugger Height through Base Settings screen.
1. Verify the correct board thickness is entered in Setup Page 1.
2. Follow instructions on the screen. Then after completion power down.
3. Power up, reset and verify snugger height.
