One of the bits missing from the Enhanced Machine Controller for a long time, was the ability to control lathes.
This has changed recently. EMC2 can now succesfully control lathes as you can see from the next few chapters.
However, although it already works, support for lathe is constantly beeing improved as new features are planned and get added (lathe canned cycles, constant surface speed to name but a few).
Using AXIS to control a CNC Lathe
By including the line
LATHE = 1
in the ini file, AXIS selects lathe mode. The ``Y'' axis is not shown in coordinate readouts, the view is changed to show the Z axis extending to the right and the X axis extending towards the bottom of the screen, and several controls (such as those for preset views) are removed.
Pressing ``V'' zooms out to show the entire file, if one is loaded.
When in lathe mode, the shape of the loaded tool (if any) is shown.

The code used is a standard g-code generated by a commercial CAM package. The file can be downloaded from the CVS repository.The result
