Thanks, Andy
Both dxf files open fine in my Cambam. No problem. Even the previous dxf that I sent you guys. What you did solved the problem creating the Gcode. Cambam creates the Gcodes now, but maybe there is still a problem with the code because it does not recreate the image in CNC Simulator. What I get is lines and circles with no sense at all. There is something wrong still and I will download that version of Cambam to generate the Gcode from those dxf files you've sent to me.
I'll keep you posted.
Thanks again, Andy
