      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

              Made a step forward,

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