I've just created a branch on github
https://github.com/mark-v-d/linuxcnc/pull/new/g7x
in which I implemented G70, G71 and G72.
Two demo files are included.
lathe_g70_71_demo.ngc
Shows how G71.1 and G71.2 can be used to use a roughing tool
without much back angle to remove most of the material.
lathe_g7x_quadrants.ngc:
Shows the directions in which you can use the new codes.
No tool compensation just yet, I'll do that soon.
Probably not working, in incremental mode.
Not tested yet if both G7 and G8 work.
I don't think O words in the sub work.
regards,
Mark.

X = Starting X (default is current position)
Z = Starting Z (default is current position)
D = distance from path (default=0)
I = cutting increment (G71/G72) (default=1)
P = Passes (G70) (default=1)
Q = sub number (mandatory)
R = retract (G71/G72) (default 0.5)
