Emco PC120 Turn

Yes.
A typical mach tool change for me would of been-

G0 G53 X0 Z0
T0101

I say would of been, because I no longer use Mach, but I wrote enough code to know how to get it do what I wanted it to.

G53 should be valid, as it's telling Mach to use Machine Coordinates (i.e. ignore any tool/work offsets). The only thing I can think of, is do you have a good homing routine, with the axis referenced LEDs turning green after homing/referencing?
Something tells me if the machine isn't referenced, then machine coordinates might not work.

I reference before I move and I ensure that Machine co Ords are green and Zero. I use this as my 'reference' and my tool offsets are based against the X Home position.

Ill take a pic tonight but Mach 3 tells me I cant G53 in Mach Turn. It might not like it in the Macro, Ill do an MDI tonight and see.

So inserting G53 X0Z0 works well but I need to copy that into the G Code.

I am using the default Fanuc post processor in Fusion 360, it would be good to be able to edit the post processing somehow. It also adds G28 commands that my Lathe doesnt like.
