Ok first question, does all your axis work correctly? especially the A axis? Reason I ask is you have the A Dir pin set as 14 and the Coolant is also set to that pin, that shouldnt be, so ifg your A works correctly then that is the wrong pin for the coolant. Assuming the A is correct and all other axis are likewise then that only leaves pins 3 and 9 free so try them.
You also have pin 17 as the A Axis Dir pin and also as an Enable, that shouldnt be so try disabling the Enable Output and see if things still work, if they dont then post back.
