3. Select the “Reset” button to reset the cycle count to zero.
4. Select the “Stop” button to leave Setup mode and go to Cycle Stop mode.
8.2 Calibration
The workcell has one of three calibration methods: Standard, Operator Defined, and
Sensor Defined.
If a Sensor Defined or Operator Defined method is installed on the workcell, the machine
may or may not automatically enter its particular calibration mode when entering Auto
mode. This will depend on which application the workcell was set up for. Refer to Section
8.2 for more information on different calibration sequences.
8.2.1 Standard Calibration
Standard Calibration is the easiest calibration procedure. Each head on the gantry will
have a set reference position. The operator can select the head and move the gantry to its
related position. When at the preset point, the operator must physically reposition the
dispense needle to confirm that the calibration is correct.

Note: For a calibration plate, each valve tip should align with the crosshair center
point. If it does not, physically move the valve until it does. This is only for the
mechanical alignment of the head assembly.
1. Select the “Calibration” tab in Setup mode.
2. Click the “Select Position” dropdown menu to change the active valve or tool.
3. Select the Move to Position - “GO” button to move the selected valve to the related
reference position. This procedure is useful when maintenance is performed that
might change the alignment of the gantry (e.g., replacing a valve after a head
collision).
4. Examine the position of the needle or calibration tip as it relates to the calibration
point (e.g., crosshairs).
5. If the needle or calibration tip is not directly above the point, manually bend the
needle or adjust the tool position so that the needle or calibration tip is above the
calibration point.
6. Select the Restore Default Position - “GO” button to restore the calibration
position back to factory defaults.
7. Select the Teach Position – “GO” button to reteach the predefined calibration
reference position. Use the Teach Pendant to move the desired tool to the
calibration plate. If installed, press “PURGE” to toggle the pneumatic Z-slide up or
down. Press “TEACH” to save the position.

8.2.2 Sensor Defined Tool Calibration
The sensor defined tool calibration block consists of three sensors with one for each
axis (X,Y, and Z).
Figure 37: Tool Calibration Sensor Block
Refer to the PathMaster® Manual for more information.
Warning: Do not unplug the cable from the calibration block while the system is
powered on, as this could damage the sensors and/or motion controller.
