Preprocessing

G code: G40, G41, G42, G43, G50, G51, G52, G60, G61, G70, G71

Function: The commands activate preprocessing modules, such as SMC_SmoothPath, SMC_RoundPath, SMC_AvoidLoop, SMC_ToolCorr, SMC_ToolLengthCorr, and SMC_ToolRadiusCorr.

Note

If the Show preprocessed Path option is selected, then the edited path is visible in the graphical editor.

G code word	Description
`D`	Tool radius or overlay radius for `G51/G52`.

Commands for tool radius compensation
G code	Description
`G40`	Ends tool radius compensation
`G41`	Starts tool radius compensation to the left of the workpiece
`G42`	Starts tool radius compensation to the right of the workpiece
`G43`	Starts tool length compensation. The tool offset to be corrected is specified with the parameters `I, J K` (for `X, Y, Z`). The tool length compensation is deactivated by setting the parameters to zero. After activation or deactivation, ramping in or out is performed. For more details, see `SMC_ToolLengthCorr`. Note: The length of the tool must not change during an active tool radius compensation because it can break the path.

Commands for angle rounding and angle smoothing
G code	Description
`G50`	Ends the angle rounding and smoothing
`G51`	Stars the angle smoothing by means of `SMC_SmoothPath`
`G52`	Starts the angle rounding by means of `SMC_RoundPath`
`G70`	Ends the smoothing of additional axes by means of `SMC_SmoothAddAxes`
`G71`	Starts the smoothing of additional axes by means of `SMC_SmoothAddAxes`

Commands for loop suppression
G code	Description
`G60`	Ends the function for loop suppression
`G61`	Starts the function for loop suppression by means of `SMC_AvoidLoop`
