Y axis not zeroing

Y axis not zeroing when starting cr 10 se. It tries about 12 times then gives an error with a qr code to fix the problem but nothing is there. I’ve posted this before but no one is responding. Please help.

It’s a common oversight in the factory. Don’t stress.
Tighten the Endstop post next to the belt next to the stepper motor.
Check the x axis as well.
Happy printing. The CR10 SE is a very nice printer.
