It is useful to prevent unwanted torch dives caused by unstable tip voltage during short cuts. The rule parameters may be edited and saved by clicking 'OK.' 'Start code' and 'End code' are the M codes which will be inserted into the g-code program at the beginning and end of the path rule's effect.Īdditional types of path rules may be implemented by clicking the 'Add rule' button at the bottom of the Path Rules editor window.ĭescriptions of the default path rules are belowįunction: disables THC for holes with a diameter under the 'Smaller than' value.įor most materials the height change across a small circle is too small to really need THC motion, but the tip voltage is unstable during the cut. To edit a path rule double click on the name of the rule, this will open the rule options. To disable or enable path rules click the checkbox to the left of the path rule name. By default all the path rules will be enabled.

Can also perform machine specific functions and macros user or builder. Miscellaneous function, M followed by a numerical code, defines program flow and can control auxiliary functions such as coolant. The default rule set will have been installed by the 'AvidCNC for SheetCam' installer. Preparatory function, G followed by a numerical code, specifies machining modes and functions. The Path Rules window will then be displayed.

To open the cutting rules editor press the Cut Rules button on the left of the Tools menu on the left of the SheetCam application window, or use the drop down menu Tools -> Cutting Rules. You can configure and run Mach4 in demo mode prior to licensing the software.
