7.1 Calibration
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.
X, Y, Z Calibration
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.
1. Set-up a gauge block or standard and indicate it parallel to the axis you are calibrating.
Note: Put the display in Inch or mm to match your gauge block. Recommended gauge blocks
are 150mm or 6” for all axes.
1. Set a 2µm indicator in the spindle and move it up to one side of the gauge block or standard.
2. Go to setup mode, and enter Service Code 123.
3. Select the axis you want to calibrate: X, Y or Z.
4. Follow the instructions on the screen to complete calibration.

7.2 Backlash Compensation
Every mechanical system has at least a little backlash or lost motion. It is produced by the small amount
of play between the mechanical components, and mostly by the accumulative bending or elasticity of all
the parts of the drive train under load. The backlash constants are factory set, but may need to be
adjusted periodically. They are set at the factory by running a ballbar test using a Renishaw QC20 ballbar
system. If a ballbar is not available, then the following procedure can be used.
1. Set a 2µm dial indicator in the spindle, and touch off on a block or the vice along the direction
(X, Y or Z) you wish to check.
2. Load the indicator to zero from one direction and zero out the DRO.
