Reply To: 3D print shifting



Actually I tested same thing as you wrote, but the issue is still seen even though middle assembly is tight.
I can see frame is not stable either due to tall height when printing. X and Y axis pipe is shuddering when the motor starts to move or stops but it is not while moving.
I think additional X and Y axis pipes in the middle of the legs or leg holes for rigid fix are required to protect shuddering with tall Z axis.
