I concur with Andy. Some of us use plasma cutter on a daily basis in production and some of us (Me) do consultation to sort out machine problems on a daily basis. From experience and seeing many good and many bad machines, the best production solution is a floating head that will detach when run into a job. I have seen many alternative solutions that all end up being scraped and redone to floating head. It is my opinion that the only good and maybe better alternative is the capacitive sensing THC system. The simpler the solution the lesser the troubles:)
