Issues since upgrading to 1.20\. printer is not usable



  • I'm having weird issues with the new firmware

    • Meshleveling: , the result are either +- 2.1 above the bed or +- 0.8mm under the bed. what is realy weird is that this alternates between those 2 results every time I run the mesh leveling. I use an Ir probe
    • When starting aprint, the nozzle stays 5mm above the bed, when I lower it with babye stepping, it goes back up again as soon as a new gcode command is processed

    the second one makes my printer (E3D Bigbox unusable



  • I got the second issue fixed by removing G29 from the config.g

    first issue still there



  • issue is back

    does anyone else have this problem ?


  • administrators

    Please post your config.g and homing files.



  • Made a step forward,

    It seems that this happens when I do mesh leveling, and dont reload with M375
