5.2.1.2 Z-Axis Gib Adjustment
(See Figure 21)
1. Mount a dial indicator on the Z-axis ways and locate on top of the
carriage.
2. Lift the carriage up to measure the amount of play. The dial indicator
should not move more than 0.025. If it moves more tighten the gibs.
Make sure not to over tighten the gibs.
3. This procedure with the dial indicator will need to be done in the front
and rear of the saddle.

5.2.2 Calibration & Backlash Constants
Calibration and backlash constants were set as part of the installation and set-up of
your system. They should be re-set when indicated in the Troubleshooting section or
after the replacement of the computer module, or any parts of the drive train.
Calibration is used teach the machine a known distance. We typically calibrate our
machines over a 150 mm distance. There is no limit to how far you can calibrate the
machine.
5.2.2.1 Calibration
NOTE: Calibration usually is only done after replacing a computer module or adjusting
the drive train.
1. Recheck machine level and adjust as necessary.
2. Press the “SERV CODE” soft key.
3. Input 123 on the keyboard, then press the “INC SET” key.
4. Input the “X” key to tell the control the x-axis is being calibrated.
5. Place the .002 mm indicator in the spindle and set up the metric standard on the
cross slide. Make sure the standard is parallel to the cross slide by using a
