Congratulations on your first machine rebuilt. Looks like you did well. This is a very good machine to own. I have an Emco C5, which I like, and have been looking at acquiring one of these larger versions with automatic chucks.
I would omit the MDI screen. Don't think a dedicated MDI screen is needed. The MDI is needed both on the setup screen and the run screen.
On the main screen needed also spindle and coolant control buttons as well as tool number and offset DROs - the new DROs Brian has just added. Also, these DRO's are needed on the setup screen. Spindle control is also needed on the setup page, since you touch off on the setup screen.
Issue number 2 is resolved - apparently was my fault of some sort. Now seems to work.
Issue number 3 appears to be a touch screen issue - if you statically hold your finger on one spot it just quits after a couple of seconds. Moving the finger around on the button keeps it thinking you're still there. Hope I can find some parameter in the touch screen software to resolve this.
1. Now works. It appears to be the button that is required. 2. Yes. Nothing happens. But put the same screen on this PC and it seems to work... Will go back to the machine PC and see if there was really a problem or it was my fault. 3. Yes, I am positive I am in continuous jog mode. It seems to me like the the touch screen quirk - as if it doesn't like to be held continuously and quits after a couple of seconds. Is it possible?
I have created a new screen using MachScreen. I took the standard mill screen set and deleted all the pages accept diags and settings. Then I created another page that would be the main page for all stuff. The main screen is designed for a touch screen with and has large buttons.
It seems to work fine except for several things which I can't figure their relation to a specific screen:
1. I define arrow keys to jog from the keyboard, but they just don't work. Simply loading the standard screen fixes it. 2. Some commands don't work from the MDI - G1's work fine while G0s not. 3. I have job buttons on the screen (which is a touch screen), but pressing them the axes would only jog some distance (which is not constant, but very close to such) and then just stop - feels like jogging is set to incremental, while it's not.
If you ask me, 20mm is definitely overkill for this machine. Keep in mind that the ball nut will be huge - the mounting flange being some 50mm in diameter. A 16mm diameter will have plenty strength for this machine. Even a 10mm one will cope well with those loads, but a 16mm one will not even "feel" the them
