Lightobject Z table only travels in one direction

I’m first timer in the forum. I just added the Lightobject z table to my K40. I need to know if any settings need changing in the smootie configuration file. Connected z table to z port on cohesion 3d board. Motor spin only in one direction. Reversing direction in Lightburn does not make a difference.I have plugged the z table to the rotary port and z motor changes directions. Plugged Rotary to Z port and only travels in one direction. It seems to me that the issue is with the settings in the smoothie file. Any help is greatly appreciated.

The nice folks over at Cohesion3D have some great resources to help you. Have a look at these search results.
