Klipper shutdown during the START routine of a print

Request a temperature tower from orcaslicer. Move it to approx 5cm of the front border of the plate. Start the print and Klipper shuts down in error "unhandled exception". Klipper restart or firmware restart is useless, need to reboot the raspberry.

Moving the temperature tower to approx 10cm of the front border of the plate solves the issue.
