Since you've tested the switches I assume the closure is getting to the controller. So that points to software.
You need to set the #defines in the CONFIG.H correctly. First, to enable HOME. Second, to set the switch sense (HIGH or LOW).
Below is what I used on the three CGE Pros I helped my pals convert:
#define HOME_SENSE ON // OFF, ON*. Automatically detect and use home switches. For GEM mode only. Option
#define HOME_SENSE_STATE_AXIS1 HIGH // HIGH, State when clockwise of home position, as seen from front. Rev. w/LOW. Adjust
#define HOME_SENSE_STATE_AXIS2 HIGH // HIGH, State when clockwise of home position, as seen from above. Rev. w/LOW. Adjust
// Signal state reverses when travel moves ccw past the home position.
These are all located in the block labeled // SENSORS in the CONFIG.H file
Hope this helps.
