1. Default Plane
When LinuxCNC’s interpreter was first written, it was designed for mills. That is why the default plane is XY (G17). A normal lathe only uses the XZ plane (G18). To change the default plane place the following line in the .ini file in the RS274NGC section.
RS274NGC_STARTUP_CODE = G18
The above can be overwritten in a g code program so always set important things in the preamble of the g code file.
2. INI Settings
The following .ini settings are needed for lathe mode in Axis in addition to or replacing normal settings in the .ini file. Gmoccapy uses also the mentioned settings, but does offer additional settings, check the gmoccapy Section for details.
[DISPLAY] DISPLAY = axis LATHE = 1 [TRAJ] AXES = 3 COORDINATES = X Z [AXIS_0] ... [AXIS_2] ...
