That is the 1024.lset, what you seem to be wanting is the 1024.set, ie the mill screen.
If you copy the 1024.set to your desktop, rename it pppmike.lset then paste it back into the Mach3 folder then load it you should be fine as far as the wizards etc go, not sure having the extra axi etc will be that great but you could always edit the screen to look like you want.
I made my own screenset up for the lathe as I am not keen on the standard lathe screen (1024.lset as in my pic)
