Hi everyone, I'm new at this forum and I need some help

I'm using mastercam for solidworks, when I post the toolpaths to G codes, there are some wrong paths coming. I mean my simulation is correct but machining is wrong on some surfaces. I need to find a post processor for Fanuc Robodrill 21i-E CNC (Control unit is 31i-ModelA-5)

Can anyone help me ?

I used standart 3 axes mill in mastercam but the cnc had problem,
" over tolerance of radius "

Thank you ...
