Why do you think is preferable to use the rotation center as Z0 rather than the radius?
Hello
Because CamBam use the stock surface as rotation radius for wraping and to get stock surface = radius, Z = 0 must be set at the rotation center. The other advantage is with the driving software, to compensate the feedrade depending of Z position, if Z=0 is at the center, the setting is OK for any diameter but if you use Z = 0 at the surface, you must change the "rotation radius" value(*) for feedrate compensation each time you change the diameter to machine ... and in addition with 4 and 5axis, Z=0 at the center is the norm.
(*) In mach3, it is on the Settings(Alt-6) screen, and because Mach3 have a bug, for Z=0 at the rotation center, instead to write 0 for the rotation radius, you must write a very small value like 0.00001 because if set to 0 the radius compensation feedrate is disabled.

Very good, that must have taken forever.
Yes sure ! .... months !!! and the arrival of NCnetic helped me a lot to do tons of tests because the result on Mach3 screen is not really clear ! It is a very nice software.
Thanks for the feedback, changes done
