Inconsistent Z-axis homing on ultimaker 2+


Recommended Posts

Posted · Inconsistent Z-axis homing on ultimaker 2+

As stated in the title. Every print, my bed shifted up/down 0.2-0.5mm, requiring aggressive releveling of bed during skirt (fortunately so far it has been within adjustable range of the bed leveling screws). My machine has been more than 5 years old, originally a Ultimaker 2 which is upgraded to 2+. The motherboard burned itself out some years ago too so that was changed to a new original board.


I'm wondering if I'm just dealing with an old homing limit switch or if this is a software issue.
