you bet hood
but i still have a problem mastercam is posting in radius with the mach3B post and when i change the post to fanuc it is ok posing in diameter but fanuc instead or i,j they use r so in mach3 they will come out circles
i need a mach3 post for mastercam that post in diameter
can some one help me !!!!!

[Hood]

Strange, I work in Dia mode and use R for arcs and its fine, did you try changing the reversed arc setting again after you used the new post processor?
Can you attach a bit of code that you have issues with and I will see how it looks for me.

dear hood 
belive it or not now it is posting in diameter and it is a fanuc prosesor and mach3 is fine with it 
but dont ask me what i did cause i dont know
do you use mastercam to generate gcode?

[Hood]

Hmm....
You just shook the memory here, i don't use MasterCam, but Dolphin has a few different post processors for the
lathe, ie one for radius and one for diameter.  So may be similar. Additionaly check if there is a turning mode that you can be in
when bringing in the file as that could just be a click and you may have mistakenly done it.

FWIW,

I don't know if this is the same problem i had but latest version of mach would take all the radius moves and make circles out of them or a figure 8 i had to delete that version and go backwards in version's to correct the problem working fine now.
