Laser does not start at the correct starting point

My laser Atomstack A70 Max starts every job at the position wher it is. It does not move to the correct spot. What am I doing wrong?

Perhaps you have Start from: Current Position selected:

If the machine has homing switches and homes correctly when you turn it on, then you can use Start from: Absolute coordinates to map the LightBurn workspace precisely atop the machine platform.

Thanks for the quick reply.
I will be back home in a couple of days and try it immediately.
I will inform you with the result

Kind rgds
