Crash y axis moves back to the stop without stopping

Hello everyone,
When sending a job from the bamboo studio, the head moves forward and then all the way back and it moves to the full stop. It carries out this movement a few times and also shifts it to X. I know that the P1S is loud, but you can hear it in the back It’s clear that it hits the stop. Data and correct printer are correct. What’s strange is when I switch it off/on and do a calibration before printing then it prints as always. If I then send a second print, it no longer works, as if it doesn’t remember the end points.
Do any of you have this too? here is a Video
Best regards
