Z Axis always moves towards print head (corexy)

smoothie-forum
(breakfastsmoothie_SW) #1

Just got a new second hand corexy style printer. I have taken most of it apart and put it back together. I had it working, but just replaced the hot end. Now the z axis only moves towards the print head. I’m very new to smoothieware, and I’m hoping its just a config issue please help!!

Config is as follows:
