Ortur Laser master 3 LE - Start Position

I have an Ortur Laser master 3 LE.
I have the following problem: whenever the laser head moves back to start position, there is an error and the laser head rattles and a warning sound occurs.
In lightburn the current position is x=-20 and y=-20. I start from absolute coordinates at the bottom left.
The current firmware update is installed.
What can I do. Thanks a lot.
