Nozzle crashing into the bed

Post by Arckany » Fri Jan 21, 2022 10:52 pm

Hello,
I just got a 3D Touch sensor (Not BlTouch) for my A20 and i watched almost 10 videos and searched a few forums on how to set it up. But i keep running into the same issue. The Z-Axis won´t calibrate. The Nozzle keeps running into the bed. Even a Different Firmware didn´t help me. I also tried to use a Z-Offset and to change the mount height of the 3D-Touch but nothing helps. If i hit Auto Home, even with Z-Offset set to 0 ,the nozzle crashes into the bed until i turn the printewr off. The 3D-Touch just flashes red after the nozzle hits the Ground and does nothing until i turn the printer off. At the moment i am thinking about returning this sensor because like this it has no use for me.
Maybe someone knows what to do? I am done.
