eliminate any overlap entity if it helps 

this is a test Z2G file, lets see if someone can figure it out.

g40 test.ZIP

g40 test.EIA

I am using the c axis and 2d milling tool path, I haven't seen feed 500. in any of the tool parameters.

AND ONE MORE PROBLEM ........

CODE OUTPUT WILL HAVE M511 AND M513 EVEN MACHINE DEFINITION DOES NOT HAVE SECONDARY SPINDLE...

have tried to change inverse feed option but no help...
