 5  After you install LinuxCNC several sample files are placed in the
 6  /nc_files folder. Make sure the sample file is appropriate for your
 7  machine before running.

 9  == Mill Examples
10  
11  === Helical Hole Milling
12  
13  File Name: useful-subroutines.ngc
14  
15  Description: Subroutine for milling a hole using parameters.
16  
17  === Slotting
18  
19  File Name: useful-subroutines.ngc
20  
21  Description: Subroutine for milling a slot using parameters.
22  
23  === Grid Probe
24  
25  File Name: gridprobe.ngc
26  
27  Description: Rectangular Probing
28  
29  This program repeatedly probes in a regular XY grid and writes the
30  probed location to the file 'probe-results.txt' in the same directory
31  as the .ini file.
32  
33  === Smart Probe
34  
35  File Name: smartprobe.ngc
36  
37  Description: Rectangular Probing
38  
39  This program repeatedly probes in a regular XY grid and writes the
40  probed location to the file 'probe-results.txt' in the same directory
41  as the .ini file. This is improved from the grid probe file.
42  
43  === Tool Length Probe
44  
45  File Name: tool-length-probe.ngc
46  
47  Description: Tool Length Probing
48  
49  This program shows an example of how to measure tool lengths
50  automatically using a switch hooked to the probe input. This is useful
51  for machines without tool holders, where the length of a tool is
52  different every time it is inserted.
53  
54  === Hole Probe
55  
56  File Name: probe-hole.ngc
57  
58  Description: Finding the Center and Diameter of a hole.
59  
60  The program demonstrates how to find the center of a hole, measure the
61  hole diameter and record the results.
62  
63  === Cutter Compensation
64  
65  To be added
66  
67  == Lathe Examples
68  
69  === Threading
70  
71  File Name lathe-g76.ngc
72  
73  Description: Facing, threading and parting off.
74  
75  This file shows an example of threading on a lathe using parameters.
