While I have swapped a new mainboard, swapped a new color change sensor(30735-04), swapped a new actuator, color change motor(30645), swapped a new Z index-home opto(30144-04), but the problem still remain. The situation is like this:- 1) When I swicth on the power, usually this standard machine will initialize by changing the color need to the home position, BUT it doesn`t do that. 2) When I try to switch needle(change color needle), AOS shows up an error message "HEAD IS NOT UP", when I check the head timing, the current Z position is 0.0 3) Even I have swapped a new mainboard (XT model), after configuration, it should be fine, but the problem still remain. Can anyone help me on this?? Thanks.
