Y-axis offset problem? flow calibration seems not right

Hi, it seems like there is a problem with my printer/heatbed/coolplate. Every time I print, it seems that the lines that the printer draws on the outer top edge (to calibrate???) are outside the norm on the y-side. I have outlined the lines I mean in red on a picture.
If the plate is not 100% at the back of the catch edges of the bed, it is sometimes even that he does not even print it completely on the print bed. What could be the reason for this?
I already opened up a ticket. They told me to check the hotend for bending, but thats fine… The y-axis seems also debris- and obstacle-free… any other ideas?





Your nozzle/hot end may be bent. Straighten or replace.

If the nozzle is straight, loosen the bed mounting screws, push the bed to the rear, tighten the screws. Two screws in each of three locations:

Make a greater effort to place the plate properly. Saying that the problem occurs “sometimes” means the plate is not touching the rear bed corners.

The screw thing did the Trick! Thx a lot :slight_smile:
