Yes, to independent axis ratios, as well as slaving A axis to X,
portions of the rotary axis are implemented (only radial feedrate
adjustment remains to be implemented in software), and the G-code is
presently equivalent to Nist 274-NCG as indicated in the EMC user
manual at linuxcnc.org

Cutter comp is working very well G41/42/40

G43 Tool length offset (plus)
G49 Cancel tool length offset

are supported, but G44 is non standard and is not supported.

The work offsets and auto tool setting routines version should be
released this week. G10 is presently supported, but there are better
ways to work with tool and work offsets in a windows environment.
