Or should I bolt it down as I weld it up?
Best if bolted down but it will be heavy anyway so won't exactly float away. Thing you need to avoid is not putting machine in twist.
Don't know how you plan to get X axis rails on same plane but which ever way then do it after the machine has been situated where it's going to live and fastened down.

Don't bolt it down has your building it. When building try to find level and flat surface that is not in twist to work from, don't just work from floor unless you absolutely know it's perfectly flat and not in twist. If you don't have decent surface then It's worth taking the time to build one. If the work surface is in twist then the frame will be in twist when welded up.
