Figure 8.7 Letter Milling Parameters dialog.
Besides Retract Height you can choose if retracts should be carried out in rapid or
feed mode. Once finished click OK to close the Parameters dialog..
A note on the three zeros:
The zero of the text milling (Part Zero) is here placed at X-68.0; Y-30.0, referring to
the Drawing Zero in the middle (X0.0; Y0.0). The Machine Zero is fixed by the
machine manufacturer (here X0.0; Y40.0) and cannot be changed. The difference
between the values of the Machine Zero coordinates and those of the Part Zero, in
our example ∆.X = -68.0; ∆Y = -70.0, referring to the Machine Zero, is allocated by
the CNC as the 'Zero Point Offset' (e.g. G54).
