K8400 calibrating platform

First I had a problem with autohome because the cable of the Z endstop didn t work.
Got this fixed now. Autohome works, but the correction of the height of the platform does not.

Finally I cannot fasten the screw at all, it has reached its limit and the distance between the head and the platform has got bigger, not smaller. About 5 mm.
I tried to loosen the screw a few times with little effect too.

I could get the platform higher with the screws under it, but that is not the way tot do it, I guess.

Did you follow the instructions in this link?

sure !
I began with one turn and it seemed not to have changed a lot, another, some more
I alsoo tried to loosen the screw because I thought the manual was wrong, but no effect

Like i said before, now the screw has reached the end, cannot fasten it more and 5-6mm distance

Crazy question and I do not want to offend but did you mount the end stop upside down?

It is mounted as on the picture

Could you post a picture?

a picture of what precisely?

I am thinking the flag for the Z end stop.
Maybe it’s not mounted correctly.

not simple to make pictures, I checked the instructions, I screwed the calibration piece out and back in, I dont think there is a way to do this wrong. i do not know what you mean by ‘the flag for the Z end stop’

i repeated auto home, distance between nozzle and plate about 2mm (checked it with a folded paper)
every time I screw the calibration nut to the right the distance gets a little bigger

I will make some pictures but what are you going to see ?

Because you picture is so close I can’t tell but is this the end stop?
Could you post a picture of the back of the printer?

This is strange.
You might try swapping the end stop with the X or Y
I am running out of ideas.

adjusted the bed with the screws under the plate and it works for now

I apologize.
I would have mentioned that but I thought you knew.
Glad to hear everything is good now.
