For this tutorial, your probe needs to support these two probe angles. They must be calibrated:
T1A0B0
T1A90B-180
Alternately, you may use a star probe with tips that can measure the top face and the front face of the part. If your probe on your machine can do either of these, then just make sure the probe in the Probe Utilities dialog box (Insert | Hardware Definition | Probe) matches what is on your machine.
Note that the instructions in the remainder of this tutorial assume that you have a probe with a wrist with the above calibrated angles.
Once you have a probe with the above calibrated tips, the next step defines what features to measure for the alignment.
Go to the next step: "Define Alignment Features"
