Autoleveling error, Nozzle scratches the bed

sysphpsysphp
in Extruder & Bed
Hello! 
I am a newbie, so I apologize if I say some stupid or my English is bad.

I Follow the indications in the documentation"documentation/repetier-firmware/z-probing/"

And calculate a distance to the bed of 1.64 mm, but when it starts to print I scratch the whole bed. I had to touch bed coating by hand, and just in 2.10 mm it worked. 
I probe to move the z axis 10cm and was well calibrated.

any ideas?
Thx!

    What is your homing setup? If z probe height is calibrated correctly, bed coating should be 0.

    this?

    I mean more are you homing z max or z min and if z min do you use z probe for it, which is required to work correctly as z min endstop can not be fixed if you use autoleveling. In that case the 0 would be correct, but z min pin should be same as z probe pin. Then you can adjust with z probe height. You should use dev version of firmware in that case.

    Sorry! my home z is Z MAX, and Z MIN is the probe. i need the dev version?

    Then set endstop distance to a value larger then bed tilt, e.g. 2mm.

    Dev version has solved many autoleveling issues so with these problems it is often better.

    this app repetier.com/firmware/v092/ says the config file (branch develop) is invalid, and the size of the config file is the double...
  • RepetierRepetier
    Not sure what you mean. The link is for 0.92 and not dev version. Config file is bigger in dev but double sound a bit much.
  • sysphpsysphp
    How is the link to configure the dev version?
  • RepetierRepetier
    Start pagein 0.92 has a dev button on first page to switch.
