Positioning
Command G0, G92
These commands are used for changing interpolator positions.
In case of G0 the changing is done by moving on a line to the next position. In
contrastto G1 the G0 elements aren't modulated with path-preprocessors like tool
radius, smooth path or round path correction.
With G92 the position of the interpolator is set by jump. The consequence is, that
these jumps are executed on the axes, except when programming features like
MC_ControlAxisByPos.bAvoidGaps:=TRUE prevent this. „smc_controlaxisbypos“. If G92
is applied in a CNC programm before the frirst positioning element, then it can have
the designed use of setting the start position.
