Setup: Smoothieboard 5XC v1.1, iOS, Octoprint, coreXY with dual Z steppers controlling bed height, PT100 controlled AC bed heater. Everything seems to be working right during homing and checkout. Z-axis min_endstop set to 0 with bed at hot end (up). Positive Z movement lowers bed. Z-axis homing brings bed back to zero. But starting a print z-axis tries to go up instead of down (lower). I could use a sanity check.
