Camera calibration

Hi there, I am a new A250T user and facing out an issue with the camera calibration.
I have done it once before I inserted Snapmaker in enclosure without any problem.
It cutted the quare in the sheet paper fine.

But after I attached it to the encolsure I am not able to do a new camera calibration.
If I start it the laser is trying to cut the square at the very left lower corner.
Laser is even going outside the workplate.

For me it looks like the origin point has changed, but I do not know how to fix this.
Can someone help me to fix this issue.

thx Peter
