Is there any way to continue on with a project running mach 3 after a power shut down.

Hi,
if you shut Mach down gracefully and park the machine at a known location, usually home, at shutdown then you can continue
with a project. If however Mach does not shut down gracefully or the power is suddenly removed then NO its not possible
to restart a project without some detailed setup, ie locating the partially complete part in the workspace.
