Not sure I understood about the xml.  I have never altered the xml and ran several programs.  When I upgraded to bobcad v23 that when things went goofy.  The have told me that the code is good and have run a simulation to verify.
I jog to touch stock and zero out dro's and run program.  It is not making the correct alignment in the y axis with all the rectangular shapes.  And I noticed that when it returns to the stock origin it tries to go further in the y direction.

Hood,
Still having difficulty with y axis.  It's as though it picks up steps in y axis as things are not lining up.
What can I check.

Try doing some simple squares or rectangles and see if they come out fine, try with a feed of 40 like is in the code, it could be missing steps.
 I am still a bit unclear regards the BobCAD code and your toolpath view, does it show the same as the screenshot I posted or does it look wrong?
 If it looks wrong then it must be something in your xml or maybe even tool offsets.
 What I was meaning about the xml was it looked fine when I loaded your xml and I was wondering if possibly you had sent me an old xml by mistake.

Yes the code is the same as the screen shot.   I have tried simple squares as in the top or middle part of piece and there is still alignment issures.  It must be picking up steps because the movement goes beyong the y0 point at the end of program.

It will likely be missing steps, what will happen is as the Y moves one way it misses some steps but Mach doesnt know so presumes it got to where it was meant to be. Then when Mach moves it back it will move further because it wasnt as far away as it should have been.
 Slow down the accel a bit for the Y axis and see if that helps any.

Slowed feed down but still mustbe pick or losing steps even though the dro's are 0 both x,y travel goes beyond y0 when it returns to work offset about 1/4"

Just try with some simple code such as
%
G0X0Y0
G0X10
G0Y10
G0X0
G0X0
M30
%


See if there is a problem still.

ok next try a few combined moves, such as
%
G0X0Y0
G0X10Y10
G0X15Y5
G0X7Y12
G0X-2Y-5
G0X0Y0
M30
