    mach3 z-position doesn't change progressively

    I build my own cnc machine running mach3. i notice that when mach3 runs line N122 from the code below, the Z value on mach3 changed to Z-5.89 Instantly from z0 instead of progressively drive the motor. can anyone explain this? does it has anything to do with 2.5d and 3d milling?
    as a result of this instant change, when i stop the program and "go to z", the end mill is hanging on top of the stock (originally z0 is touching the stock)
    thank u
    here is the gcode i got from solidcam
    N1 G90 G17 G40 G80 G00
    N108 M06 T1 ()
    N112 G00 G54 G90 X150.0346 Y72.2561 S6000 M03
    N114 G43 H1 Z15.
    N116 Z10.
    N118 X150.4675 Y72.689
    N120 Z0.
    N122 G03 X150.389 Y72.6699 Z-5.89 I0.155 J-0.8078 F719.
    N124 X150.3127 Y72.6431 Z-5.9012 I0.2335 J-0.7887
    N126 X150.2394 Y72.609 Z-5.9124 I0.3098 J-0.762
