Thank you for your reply. I found one thing as picture below Locate C and B position first and then WCS origin changed into new origin X' Y' Z' and post processor updated this new WCS and posted next location (X Y Z) follow this WCS. I can not understand why and please help me fix it. Thank you.

Hi everyone, I got a trouble in Generic Fanuc 5X mill post with 5X toolpath. Post processor output X Y Z coordinate are not correct as WCS Top plane as I chose in Master cam. But When I try with Haas UMC-750 5X Mill post that changed parameter same Generic Fanuc 5X mill post. Result is Hass UMC-750 5X mill output correct X Y Z coordinate with Mastercam coordinate . I compared with post from CAMplete and result is Hass UMC post is same with CAMplete. I will show picture as below this is post from Camplete this is post from Hass UMC-750 edited This post from Generic fanuc 5X mill That is big different X Y Z coordinate with Hass and Camplete at one sample line that I show. Please tell me why and help me fix it in Generic Fanuc 5X mill. Thank you very much. I really appreciate your help.
