Broken step driver

Hi guys …
It my first time posting in a forum honestlly many times i take advantage from reading problem solving in forums so decide to post here

I have yuming laser machine recently the driver was stopped working there no any light coming from it , its 3 amp out put. 24 volt input 2 phase my stepper motor shinano 3 amp 1.8 degree bipolar

So i first tested the fuse and its ok now i want to know the next step to check the power to the step driver
What to test now and in a logical sequence

This the images of the circuit board

Thank you guys …




Any answer please…

We need a lot more information if we are to help you.
I am not familiar with “yuming laser” and that controller does not look familiar either.

Provide information links to manuf. information:
Provide pictures:

  • Of the machine & its control panel
  • Of the laser
  • Of the power supplies

Exactly what is the problem you need help with:
Laser not working? “the driver was stopped working there no any light coming from it”
Are steppers not working? “i want to know the next step to check the power to the step driver”

Sir i have already change the mainboard to ruida but my problem is the steepr motor driver are broken and i need to cheek the component of the electric circuit board to identify the broken piece the power fuse working well so ineed the sequnce to start from

Thank you
