Z axis don't want to go home

hi ,
after print , i would to make another , but z axis doesn’t want to go home . After pressing “home” it is moving up instead just a bit ,like ,if it thinks that it is on zero already. If i press button “down”, not response , only when i press button “up” and then it want to go down but only the same amount .
I reinstalled soft. ,reset motherboard , removed “end” switch , but still the same even without switch …any idea what’s wrong? thanks. I hope no motherboard …it would be second …

What do you mean by removed?
Did you disconnect the endstop?

Then the printer will think the endstop is hit all the time.

This sounds like one of the wires going to the end stop is broken.

Yep!

it was the end stop …
but when i removed it and connected the wires without that end stop , it didn’t work either … didn’t think about broken cable ,coz no idea how that could happen …
well, while i was removing the end stop i most probably broke as well that wiring somewhere … now all fixed
Thank very much guys for your help .

Glad to hear it’s up and running.

Enjoy!
