For the SP600 Probe Changer, you will take the third and final manual hit in the XY plane, on the vertical face in front of the rack between port 3 and port 4.
The prompt for the third hit in front is:
Please take a hit in the center of the vertical face between ports 3 and 4. After completing this hit, DCC calibration will begin.
Use your machine's jog box to measure the third hit in front on the vertical surface between port 3 and port 4.
WARNING: When you do this, the machine moves. To avoid injury, stay clear of the machine. To avoid hardware damage, run the machine at a slower speed.
This set of two hits establishes the location and orientation for the tool changer.
At this point, the system goes into DCC mode and measures a series of hits required to accurately locate and orient the rack.
In the next step, you review the calibration results.
