I home the machine which sends it to the switches and thats it. It will be at 0,0,0 and you run the gcode from there. Yes you would jog it off the stop with the software.
You could use an indicator of some kind when your work piece is out on the table somewhere and you want to start at one corner. What I have done is moved the cutter to the edge of the workpiece and manually set my zero from there. Generally with a wood working machine a dial indicator is not required because it's wood you are cutting and usually you take material off all sides. +/- 1/32 is plenty close enough. I don't have hand wheels on my machine but I have reached in and turned the leadscrew by hand to tweak my start position against the work piece or whatever.
Ask any questions you like. We are a patient bunch.
