[johnptc314159]

so when i edit a tool direction ( uncheck cw rotation) in cam and post out the g code.... it shows m3 which is cw rotation.  I am using haas ngc st 15 (lathe) post processor.  i searched the post and there is no M4 that i could find :(.  i thought maybe it was disabled ??    thanks john

Hi @johnptc314159 

Thanks for posting! Would you mind sharing your part with me? I did some quick tests and received the M4 as expected with the ST-15 post.

I had the same problem using the  "Doosan mill-turn fanuc Oi" post. It only seems to work if I use a tool with a CCW spindle direction defined in the tool library. It will not work if use a tool with a CW spindle direction defined in the library but then change it to CCW at the part level. Odd.
