= G Code Examples After you install LinuxCNC several sample files are placed in the /nc_files folder. Make sure the sample file is appropriate for your machine before running. == Mill Examples === Helical Hole Milling File Name: useful-subroutines.ngc Description: Subroutine for milling a hole using parameters. === Slotting File Name: useful-subroutines.ngc Description: Subroutine for milling a slot using parameters. === Grid Probe File Name: gridprobe.ngc Description: Rectangular Probing This program repeatedly probes in a regular XY grid and writes the probed location to the file 'probe-results.txt' in the same directory as the .ini file. === Smart Probe File Name: smartprobe.ngc Description: Rectangular Probing This program repeatedly probes in a regular XY grid and writes the probed location to the file 'probe-results.txt' in the same directory as the .ini file. This is improved from the grid probe file. === Tool Length Probe File Name: tool-length-probe.ngc Description: Tool Length Probing This program shows an example of how to measure tool lengths automatically using a switch hooked to the probe input. This is useful for machines without tool holders, where the length of a tool is different every time it is inserted. === Hole Probe File Name: probe-hole.ngc Description: Finding the Center and Diameter of a hole. The program demonstrates how to find the center of a hole, measure the hole diameter and record the results. === Cutter Compensation To be added == Lathe Examples === Threading File Name lathe-g76.ngc Description: Facing, threading and parting off. This file shows an example of threading on a lathe using parameters.
