Charlee,
The hopping feet are attached to the presser bar. When the foot is lifted so is the bar. The bar-foot combo is only lifted a small amount when using the darning/ hopping foot. This lifting compresses the spring less than when the foot is completely raised using the presser bar lift lever. The machine is not suffering.
