Thanks for all the replies. Before continuing, I have to said I am a newbie in
cnc.
Have been trying on EMC2 for the past 2 weeks, using Eagle and
pcb-gcode-3.5.2.11 (went thru the tutorial).
The current project I am working on (which happened to be an antenna) required

It also "cuts round the traces for the circuit" which seems to not
meet the requirements of the original query.

True, but it's what the OP wanted.
Some people have developed ways to bring Gerber files and Dxf's into eagle,
and then mill those.

Tramming the spindle will tell you how perpendicular the spindle centerline
is to that particular spot on the table surface. It will not tell you the
perpendicularity of the spindle centerline (or the Z axis) to the XY plane.

Realizing that there are signals waiting to be connected and used is a

I agree with Steve. If your Z-axis movement is not perpendicular to the

The same for spindel alignment, that should also be perpendicular to the
XY plane.
