Why does this happen to me? For whatever reason, when I print anything that has circles in the z axis, my printer will print up to the halfway point of the circle, then the z axis stops moving up, but the printer keeps printing, ruining my print. I notice that the z axis will actually move up, but then it just moves back down to the same height. It happens every time that there is a circular feature on the z axis, as shown in this example picture. I'm sure that something is happening in Cura that causes this. Has this happened to anyone else?
