A couple months ago a useful feature was added to CNC-Calc. This feature will enhance the experience for people who frequently use the same toolpath parameters. The change includes the addition of a new tree on the left side instead of a tabbed interface. New buttons allow you to Load/Save and Reset the parameters.
Pressing the Load Parameters button will list the previously saved parameters for the operation along with a description.
Parameters are saved in C:\CIMCO\CIMCOEdit7\Cfg\CncCalcParameters.xml
