Manual Operation and Setup | Presetting with a 3-D touch probe (option number 17)
You can identify the intersection of two straight lines by
holes or studs and set this as the preset.
In addition to presetting, you can also activate a basic rotation or
an offset with the cycle. The control has two soft keys for you to
decide which straight line you wish to use for this.
The ROT 1 soft key activates the angle of the first straight line as
basic rotation or as offset, and the ROT 2 soft key activates the
angle of the second straight line.
If you activate the basic rotation, the control automatically writes
the positions and the basic rotation to the preset table.
If you activate the offset, the control automatically writes the
positions and the offset or only the positions to the preset table.
