Disable homing on X & Y axes only - XPRO

Hi all,
My apologies if this has been asked before. A quick search didn't show anything.
I have a XPro CNC driver. I'm only wanting to use a single motor to build a translation table. I still want the ability to home the axis. But, from what I understand, the homing program looks for switch transitions on the Z-axis first, followed by the X and Y. And it's not just a simple case of permanently closing the X and Y limit switches.
I think the solution is to disable the homing requirement of the X and Y axes and only use the Z-axis to drive the motor.
Is there a way to do this?
Thanks for any help you guys can provide.

Hi Bob,
Thanks for the speedy reply.
So, I see in config.h, the section defining homing patterns. From the (very well written) comments, it seems that all I need to do is comment out the line:
#define HOMING_CYCLE_1 ((1<<X_AXIS)|(1<<Y_AXIS))

Then write it to the XPro and use the Z-Axis as I need.
Is it really as simple as this?

I'll give it a go and let you know how I get on.
Thanks again.

Alan.
