I recently stumbled across MobileRaker on the iPhone app store. If you are using Klipper, MobileRaker makes things so easy for you. I would encourage you to use it. And if you aren’t using Klipper, I would encourage you to check it out. I’ve noticed a significant improvement in both the quality of my prints and the speed at which they print. Usually, those two things work against one another, but Klipper has managed to accomplish both.
