Hello .
The Philips 432 controller uses something called BTR mode. It is the same thing but it depends if your machine is equipped with the module. My machine's memory can store up to 6500 lines. So it is ok for general stuff. I ve used BTR mode to run programs grater than that for 3D contouring.
To check press Manual key than Menu key than from number pad chose the correspond number for Search than in the middle of the screen it should show BTR ON , so press the F key under it. That's it
