lost my ability to move router on XYZ.

I created a toolpath on v-carve and neglected to set my z-gap above material. Z-gap above material was set for 1 inch. When I started the job it went down into some MDF rapidly. I stopped the job. After that I lost my ability to move my router in xyz direction.Could I have blown a power supply or my blackbox? Are the indicators or test points I can check for voltage?

 

I did a reset on the black box and I got my XYZ movement back. Not sure what a home cycle is but it looks like i'm good to go. That was perfect. Thanks.
