Is anyone using this? Are there additional modules necessary for mastercam do do this? Excuse me if this is stupid, I am new to the whole thing, and trying to figure out what to buy.

There is not a software just for Plasma from mastercam ,but I do know some do use it for this by setting up the post for the right outputs.

Hope this helps

I know a shop that they are using a mill level 2 package to program a waterjet machine, they post a mill prog and edit a few lines and bingo, they were working on editing a post that wouldnt need modified even though it was a quick process, I gotta think a plasma cutter should be similar but maybe not I never seen one that was cnc.Just my .02

I talked to our laser/plasma guys at work today, its all in the
post. Just like mold said, edit the post properly and
your off and running.
PEACE
:D

Like Mold100 stated I have programmed Water Jets in the past they are cool.
But it was all in the post .I made some change and all was good.
