Thanks for the feedback
If using the Manual Guide I it kinda seems like it would be easier for a first timer to pick up on it? And Doosan puts their stuff in there so im not sure if its different than standard or just has the panther image on it? It's easier to dump programs from a USB, loosing 3 keystrokes isn't worth the premium.
I can't speak to Doosan or Makino or any of the other OEMs who skin the iHMI, the machines I work with are Robodrills, so as factory Fanuc as you can possibly get. Here are some more detailed notes:
1- iHMI runs on an embedded Windows computer bolted on top of the basic Fanuc control. The whole thing actually doubles the boot-up time (you boot the PLC based Fanuc, then the Windows based iHMI kicks on over another 90 seconds).
2- iHMI is limited to the most basic, everyday operations screens, and it looks good! You can load a program, use the recovery modes, hit up the MDI. The machines I worked on have no probes, so I don't know how iHMI deals with that? It would need to be a Renishaw/Blum app within iHMI because I saw no infrastructure in the basic Fanuc setup for graphical probing.
3- iHMI can (and likely will!) crash independent of the rest of the machine. I never had this happen in a cut, but while doing edits to params or other operations (oddly, always in the old Fanuc side), iHMI would crash. You would go back to an iHMI side, and it would be frozen and reboot itself. Since it never runs the code pipeline, the machine will always be OK, but it is frustrating. Some of them get iHMI to reboot on it's own, others require a machine reboot.
4- I do not think iHMI (as Fanuc does it on the Robodrills, at least) would have any learning curve advantage, aside from a slight one. You still are dealing with Fanuc's dumb file system and almost Unix command line level interactions. There is no drag and drop, or rational file names, or anything approaching the model of how a modern phone/desktop computer work. The touch-screen is very basic (not multi-touch, like an iPad) so it isn't like you'll be playing Minority Report CNC mill operator on it.
I was originally sort of excited by iHMI, but alas... it is the minimum viable product for Fanuc to throw up a decent looking screen. The same old Fanuc bullshit is still running the show - with the crap memory + data server model, inscrutable parameter menus, cryptic setting screens, etc.
If you ever wanted to know what lipstick on a pig actually looks like, it is iHMI.
