My Form2 is making a very loud and deep “groaning” noise when the build platform travels up and down the z-axis rod between layers. When I first started using this unit, there was a deep vibration sound when the platform initially traveled from the starting position to the tank, but over the last few weeks it has started to occur during printing and between all layers. Is it possible that I need to put some kind of lubricant onto the threaded z-rod? I’ve talked to 3 other owners of the Form2 and none of them have experienced this sound.
My prints are working fine up until this point, for what that’s worth.
