Many thanks. Shall hold off doing anything until the machine is up and running for testing. So far, we know that we can generate gcode from F360 using the built-in Fanuc PP and that runs (it makes the servos go round on the bench!) but at least that means that there are no unrecognised commands or syntax errors in there. Whether it does what it is supposed to is another thing and will have to wait for now. I feel a bit of air-cutting coming on!
