Can't remember anything! XYZ will not jog

[scheek]

Mach2 is what I was using.  Just now checked ram in this other cpu and it was only 198.  The orginal was 500.  That could be the problem .  The 500 was working fine.  I will check at lunch an see.

Okay.  using a better cpu now.  Everything cranked right up.  However, I have a problem with Z axis.  When I try to move it, it hits and then green light blinks.  I unhooked another motor (X) and ran cable to Z and it worked fine. 

After light blinks I have to restart cpu to make it come back on and stay, then if I hit Z again it will do same thing.  If I bypass Z and hit XY, it does fine.  Must be in my powersuppy somewhere is all I can figure.

Any thoughts on this before I dig in it.  thanks
