Don't know about having a Fanuc instead of the Mits making any difference, but I do have to say this. Today's "safeties" are unquestionably making life not only more difficult, but actually less safe.
Not sure if that is a Mori invention, but certainly.
My Duraturn cannot graph a program by itself. It will either turn the spindle in machine lock or it will move axes in dry run, but there is no way to graph it even tough it has the graph function ( Fanuc)
The NL will also not graph a program ( or it will but not with any reasonable way to decipher what the f@ck it's doing) You can translate an existing program back into MAPPS, but only after you individually re-define the tool database for that one program alone. With doors open, you cannot send the subspindle home using G330. You can use G28, but that will first move it to it's programmed zero pos, which has the potential to crash it into the main spindle or the turret ... or possibly both.
MAPPS itself is a retarded cruel joke. After dicking with it for a half a day I've decided to just own up and try to figure out the G-code equivalents and program it offline.
Don't get me wrong, the control is bulletproof for running a machinetool, but is downright hostile to set it up. Yes, you will eventually get used to the idiocies and almost accept it as a fact of life, but I doubt it will ever be as simple and second nature as a Haas control. Doubt Mori, Fanuc or MIts gives a shit tough.....
