3. At the rear of the machine, loosen the z-axis ag; and while facing the z-axis ag, rotate it com-
pletely counter-clockwise and re-tighten it. See Figure 3.
•
Note: If the machine loses power after this step, it will be necessary to “roughly” reset z-timing.
Do so by following the steps outlined below. Otherwise, proceed to step 12.
4. Shut the machine off.
5. Engage the E-Stop button on the user interface.
6. Turn the machine on and let the system (machine and software) boot up.
7. Manually move the z-axis to its upper most position (upper dead center).
8. Loosen the z-ag at the back of the machine.
9. Rotate the z-ag back and forth to the point where the Z-Index LED is triggered.
10. Tighten the z-ag at this transition point.
11. Reboot the machine.
12. Cycle the machine to Head-Up at least three times by pressing the Adjustment and Arrow Upkeys
simultaneously on the keypad.

NOTE: Weight must be attached before needle depth.
13. Install the dial indicator (PN: 32453-01) with the adaptor (PN: 33065) on the lower arm extrusion
as shown in Figure 4. Tighten the screws enough to hold the xture securely.

14. Cycle the machine to its Bottom Center position by pressing the Adjustment and Arrow Downkeys
simultaneously on the keypad. (Be careful not to let the needle “slam” against the indicator
plunger because this may cause damage).
15. With the indicator plunger in full contact with the needle, hang the 3 lb weight from the needle
clamp as shown in Figure 4 above. Be sure its path is unrestricted and not touching the plunger.
16. In the Head Timing window, go to Needle Depth (bottom center) Release Z and manually rotate
the z-shaft back and forth as necessary to approximately locate the lowest mechanical position on
the dial indicator. The needle will be at it’s lowest point right before it begins to rise.
17. Use the micro-step command on the keypad to decrease (press the Trace key and the Arrow Down
key the angular position until the needle begins to rise and continue doing so for 0.003” more.
