Need a circuit diagram

[dyrty]

Hi guys,
I'm new here.
I need help with a circuit diagram of the scanner control from Fire Phoenix laser show produced by Unitestarlight.
One of the galvanometer is not working properly and the problem is in the circuit of the scanner control but not sure where.
I changed the galvanometer to each other and do the same with the other one.

Thanks.

Hi, and welcome to PL.
Did you rule out cables, software or dac?
Fill in your profile, such as your location.
Maybe someone can help you locally.

I returned with a request for you, maybe you can help me.
I have a Phoenix Fire laser manufactured by Unitestarlight having a small problem.
Servo motor on the axis x moves the mirror more than it should do, and hits left-right inside.
I guess it would be the fault of the x-axis servo driver but the Chinese have erased the value of the piece.
I enclose a picture of the control board maybe can anyone recognize what this is about.
I apologize for expression, but use google translate
I'm from Romania.
