Vmax,
I would not be surprised.  This file was generated
in DesignCad using a truetype font   and   saved
in vector format. (option in Designcad)
It was then exported to be a DXF file before being
read by LazyCam.

I am guessing that due to the overly
detailed DXF, that the changes in xy
are too small sometimes to generate a different
x or y ( at least withing the preciision of the
current gcode.

I have to agree the DXF file may overly complex.
I am noticing the same thing from some code
generated from Bobcad.   It generates G2 moves
with out any X or Y value which seems to generate
a circle in Mach3.  Thanks for your help. I think I'll do
some reading on the G2 and see if I can learn a bit more.
Thanks

Line 272 has  no value for X which
makes X the same as existing and
a circle occurs. I edited line 272 to
include an X value different from the
existing value and the circle went away.

I'm still confused.
I tried the file. 
Now I only see one corner where
this circle event happens.
I tried loading another computer (my laptop)
and I get the same thing.
thanks

Thanks for trying it in Bobcad.  I put the bobcad file
in mach3 and it appears to get stuck. Attached is the
screen. See attachment.

Here is the dxf file of the cutout.
Thanks  Don B

The path looks fine in the LazyCam view.
See attachement.

I also tried smaller cutter 1/16
and still have problem

I have just started using LazyCam Pro under vista (Mach3 2.4).
It's great! And for the most part really lets me get to what I need
to do quickly. Now for the confusion.

I created a dxf text letter in my cad program (designcad) .
I opened the DXF file in Lazycam. Everything looked great!
Then I pocketed the letter using .125 inch as my mill size.
Again all looked well.
I posted the G-code and flipped over to Mach3.
This is where it got strange.  It looks like as it was doing
curves it tryed to do a small section of curve but instead
did a complete reverse circle.
Probably obvious but not to me. Any ideas.
Thanks
Don B
