Z axis verification before move

I am running an old maslow with a new makermade due controller. My workflow is Autocad to DXF and DXF to Gcode using Carbide. This weekend while cutting a simple project I had a problem with the z-axis movement not completing before the sled X and Y movement. Is there a GCode command that I can insert that will verify the z axis before moving or possibly a pause that would allow the z axis time to complete it’s movement before moving on to another contour cut?

The key is to lower the feedrate on the x-axis. You can either do it when generating the gcode, or there is a max z axis feedrate setting which will automatically limit it.
