9.2.3 Optimizing the digitizing sequence
The following preparations should be made before optimizing machine and controller.
- Set up the flat workpiece with vertical face and plane surface in the machining plane (e.g. XY
plane).
- Probe the surface with probing function "Surface = Datum" ("MANUAL" or "EL. HANDWHEEL
MODE") and enter the reference plane as +0 mm.
- Basic setting of the relevant machine parameters for "Digitizing"

MP6230

- The interface must be configured in the "PROGRAMMING AND EDITING" mode, depending on
the type of desired memory for the digitized data (internal controller RAM, FE 401 or PC with
"Block Transfer" program). See TNC 407/TNC 415 Operating Manual.
- Connect FE 401 or PC to the serial data interface if necessary.
- Enter NC program with the scanning cycles "Range" and "Meander" and the scanning direction X
and the probe point interval 1 mm, e.g.
