How to config a lathe-mill machine with Linuxcnc ?

Hi,everyone ,we are developing a new machine with Linuxcnc,but met some problem now . the biggest problem now is that our machine can both lathe and mill .I'm a newbee to Linuxcnc .I only know how to config a traditional lathe or a traditinal mill machine now with ini and hal file,but I dont know how to config a machine mixed them together .Suppose my workmates used Fusion360 export a complete G-code program to me .and the G-code at least include, S command for spindle while lathe,and X,Z command for axis movement ,then there will also a C command for rotate while milling . So,if our machine has 3 servo motors(using Etherecat to connect and control the servo motor), first and second one for X,Z axis move,and the third one will be as both spindle and rotate axis C .I dont know how to config the ini and hal .Does anyone here be kind enough to share the ini and hal configuration using linuxcnc to achive such requirment ? I'll be very grateful for that ,thanks.

Maybe have a look here:
