PLEASE PLEASE HELP!!!!!

I recently bought a machine DMU60p and I just can’t handle the G7!!!
How do I have to program G7, with m54,m53????

And what angle to I use, the one where i swivel from.. so when I want to turn it 90°, what do I have to do with the head? How do I program it?

It’s a Millplus controller by the way.

Please help me out!
Kind regards Tommy
