Got the Raspberry hooked up last week, but only in simulation mode, as I had a car parked in the way of the sled. Need to go through and tighten all nut and bolts, I have zip ties supporting the pulleys supporting the weights, etc., but took a video before moving the tractor in to work on that. Not calibrated just accepted default settings, and attached the z-axis boom. Controlled through phone, via web control.
