Firstly, having home switches is a _really_ good idea.
If you really can't have them, then setting the search velocities to zero (as you have) and then homing to some sort of reference mark is better than nothing.
You should be able to jog without homing on any system.
MDI and G-code should run without homing if NO_FORCE_HOMING is set, you have correctly interpreted the purpose. (And it just worked for me in a sim config)

Thanks again for your replies Andy.
My CNC Router has Home/Limit switches but the actual machine is sitting in in another site and I've brought just the controller box home where it's more convenient to work on.
I've got them currently set to Normally Open so they don't trigger on me but will revert them back to Normally Closed when I reattach the box to the machine.
Setting the NO_FORCE_HOME=1 under the [TRAJ] section definitely did not work for me. Not sure why.

It's NO_FORCE_HOMING not NO_FORCE_HOMESetting the NO_FORCE_HOME=1 under the [TRAJ] section definitely did not work for me. Not sure why.
