So I have a He3d K280 printer and it raises all the way to the end stops and then it should lower to the min Z position however it stops about 20 mm too short and I can’t make it lower anymore..

how can I fix this?

    So you are homing to z max with end position at bottom? In this case z length determines where firmware thinks z=0 is. So if it stops too high, z length is too low.

     On the K280 printer the Z end stops are at the top.. that is fine then after the end stops are triggered it starts to lower until about 20 mm from the hot bed and I can’t get it to go lower.

    What is the homing configuration in your firmware config? Did you test increasing z length?
  • MikeCLMikeCL
    Which line would that be under?
  • RepetierRepetier
    Multiple lines that set homing behaviour and dimensions. If in doubt post the top part of the config file (not the big comment at the end). 

    The z length can be changed in eeprom editor of your host software.
