CNC Controller Repair (Any Ideas) Has Me Stumped!!

[KG7AMV]

Removed and Bench test of the PS2801-4 it was Bad! PS2801-4 replaced and Still tripping M2- Limit Switch. It passes thru a CTS 753 Series 2.2k Bussed Circuit Resistor Network RP4 On Photo 1st post. I Said wtf since I had the hot air out, I removed it from the circuit its the Last part before M2- Limit pin goes to the Xilinx XC95108TQ100 CPLD. I Lit the Software up with the RN out of circuit and No Error and no counters for steps. So I grabbed a 2.2k resistor +5V on one side and touch each pad and Hit Jog on each Axis Limit low and behold able to get a counter except for M2- pad it does nothing. So I am thinking it is in the Xilinx Chip Wondering if it took out the Xilinx.
