Fine Bore stand-off distance

This defines the amount by which the Bore cycle (typically G86) moves away from the bore after indexing, and only applies to the cycle output. You may specify this distance in Inches or Millimetres.

Cycle Z depth

This selects the method of defining the cycle depth, and applies to all cycles.

Rplane is always assumed to be absolute with respect to initial CPL.

Support G98/G99

Check this box to support the G98 and G99 codes (return to initial position or return to the retract value). If the control does not support G98/G99, their effect will be emulated.

The Code Generator Template selects the relevant Gcode if the Clearance and Retract planes are at the same level in EdgeCAM, to match the graphical simulation shown in EdgeCAM.

For controllers which do not support this function, the Support G98/G99 option has been added to the milling templates (and C/Y axis Turn-Mill template within C/Y functions). The following example output from the 3Axis Fanuc Milling template shows the effects of G98/G99, supported and not supported.

The Heidenhain TNC template differs from the other templates in that it uses M89 and M99 codes to specify cycle modality. The G98/G99 function is not supported by default, and no option exists to override this in the Hole Cycles Tab. If the Clearance does not equal the Retract plane, then M99 (non-modal) will be output for each hole position, with the relevant positioning moves.

Subroutine Cycle Co-ordinates

Check the appropriate box if you want subroutines for multiple cycles of the specified type applied to the same geometry.
