Geeetech

three I bought and all three are doing

Geeetech 3DTouch Auto Leveling Sensor So I put it and put the video in the second layer drops the needle down at about 4 layers of the needle pulling up.
I do not know why the needle goes down when others try to print videos and firmware ?

I got my new Geeetech 3DTouch Automatic alignment sensor so I put it in the video in the second layer the needle falls down if I pushed 2 things so soon and is about 4 layers to the needle pulled up.
I can not figure out why the needle goes down the other way up the press, thank you for your advice ...
