Fred, I did to put minimilltask and minimillio into emc.ini, but the 4th
axis is still no response. X, Y and Z axis is still working, I check the
source code of minimilltaskinf.cc. It seems most parameters of spindle
has sim() , for example simSpindleSpeed. Does that means the code is
only work on similation.
	Below description is my hardware and software test.   
	Hardware setup : I put another servo motor (not spindle) to 4th axis of
servotogo to card and connect the encode and command line.
	software test : Manual  
			click the spindle forward ,reverse , increse and 			decrese 
			: MDI 
			  S2000 M3 or 4
