Sometime the control resets itself or I can press the reset button on the X axis control board to return to normal. The LEDs on the axis control boards and the spindle control board blink twice per second, Jog will reset the drives, I can move Y & Z but X motion causes the problem every time. A handle motion of .01" causes a physical movement of .027", display only shows .01" movement, subsequent movements cause the problem.
I have swapped X & Y control boards and the problem does not follow, I swapped amplifier control cards and problem does not follow, I swapped the Clock board (1020-0) and problem remains, I replaced the resolver and the problem does not change. Voltages on mother board measure 5.17vDC, 12.39vDC, and -12.06vDC. The X axis ball screw turns smoothly.
Any ideas?
