Personally as someone who started with manual machines I'd think long and hard about getting rid of it unless you need the money.
You can jog the thing around and use it exactly like a manual mill without all the hassle of having to crank handles .
unless you need bigger table and longer travels there's no advantage to be found .
Then think about the hassle of moving machines , and how much a good solid mill will cost to buy along with move .
If you keep it you'll still have the cnc for the complicated stuff .
And again speaking for myself ... except for ocasionaly using it for a drill press my manual mill sits there taking up space .
I have no experience with mach .. but with path pilot I can program simple squares, circles , bolt patterns , pockets and such things and do the actual work way way way faster then I can with ole handle cranky .
Even stupid simple things like squaring up stock is faster on the cnc then ole cranky handle .
Not to mention how much longer tooling life has been on the cnc versus manual
