When I first start up LinuxCNC, I do a home operation. I don't care about the last position, what I do care about, sometimes, is the offset between machine and G54 coordinates. After I home, then the offset between these is restored, and so whatever position is shown on the DRO is the same, RELATIVE to the PART, as it was when LinuxCNC was shut down. So, in the case where I had to go back and perform more operations on a part machined yesterday, I don't have to touch off to the fixture or part, it is all restored the the previous setting. (Of course, whatever fixture was used before must be in the same position.)
I don't do this all that often, but sometimes I am using the same setup two days in a row, or need to redo something after LinuxCNC has been shut down. And, if you have not set up sensors to do machine homing, you are missing a VERY useful feature of LinuxCNC.
