Yes, I now understand that you want to pass a tool XYZAC to the G code and have
EMC2 convert the A and C to
I have found a way to do rotational shifts of the C-axis using XYZACkins. I
use the B-axis for that and just program G0 Bxx at the start of each blade
of the impeller, where xx is the absolute position of each blade; ie 0, 90,
180, 270 for 4 blades.
The B position is available and free to use in

I am confused with G54 to G59. Look at the following code and run it on a
simulation setup with Axis C rotation added:

G10 L2 P2 x10 y10 C0
G10 L2 P3 x0 y0 C-45

No I did not screw it up. My kinematics equations are an abstract from a
full XYZACkins program with dx,dy,and dz axis offsets, which have been
tested and has worked for a long time cutting impellers and other stuff. I
wanted to keep it simple to address the issue of G54, to G59 offsets.

I want to be able to use offsets of C (and possibly A) while in world mode.
Whereas it works OK in joint coordinates with trivkins, it seems to function
differently in world mode using XYZCkins
What does XYZCkins do that

Thanks for the response.
Perhaps before we go any deeper, have a look at what I have done.
I Yahoogroups, under group SA-CNC-CLUB, you will find some photos of the
5-axis machine setup and the part cut.
I tried to use a G54 in the GCODE for a C-axis offste - it did not seem to
work.

As far as I know G54 only selects a coordinate system. If you want to put an
offset into that (or any other) coordinate system
