Re: G-code question

I like to add that G1 also requires a feedrate.
Like adding a "F3." as example for 3 inch a minute.
Most controllers will linear read the line and only
use the last given coordinate for a Address in a block,
ignoring any previous called out values.
X and Y Axses Address will work on most controllers,
however if W or U is acceptable will depend on the
Program you use.
Turbocnc I belive will alow you to use most Letters.
The standard Addressing scheme is

XYZ - Linear main 3d Axes
UVW - Linear secondary Axes running parrallel to XYZ respectivly
ABC - Rotary Axes with rotation around XYZ Axes respectively

makes sense to stick with this where possible.
on a Lathe the main Axes's are XZ for circumference and depth.
Good Luck
