I am getting to the point that soon I will burn the BB instead of my rumba. I have spend the last two days with this silly machine and its homing problems. I have a BB with hybrid titan, pancake version, swapped z-axis/extruder motors and the clever3d bed. I run MBL and all is fine. Homing after MBL is fine. When I start a print, the homing at the beginning of the print goes too low always. This results aways in a failed first layer and therefore I am unable to print. What is wrong here? I never experienced this before. I start to feel hate for this auto-MBL IR sensor stuff Thanks.
