Z Axis always moves towards print head (corexy)

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:

[[code]]# NOTE Lines must not exceed 132 characters

  1. Robot module configurations : general handling of movement G-codes and slicing into moves

default_feed_rate 3000 # Default rate ( mm/minute ) for G1/G2/G3 moves

mm_max_arc_error 0.01 # The maximum error for line segments that divide arcs 0 to disable
# note it is invalid for both the above be 0
# if both are used, will use largest segment length based on radius
mm_per_line_segment 0.5 # Lines can be cut into segments ( not useful with cartesian
# coordinates robots ).
delta_segments_per_second 00 # for deltas only same as in Marlin/Delta, set to 0 to disable
# and use mm_per_line_segment
