5: Performing a Tool Change
Now that the fl oating ring has been set, there should be no need to change this
again. Simply use the tool depth gauge whenever changing tools in future.
Now fasten the material to the table (usually with quality double-sided tape)
and JOG the machine to the corner of the material.
Set the X and Y DATUM positions here by clicking
Now turn the spindle motor ON and jog down until the tool goes into the surface
and the fl oating head lifts by a few mm. Now set DATUM for Z.
Setting up different tools is now simple-just set the tool with the gauge. If

protrude and thus travel into the material.
