Board Damage.

[inchca]

I accidentaly did put X asis driver wrong way. The resistor kinda cooked with beautiful smoke.

Now my problem is display is dim black boxes. Feintly black boxes on the screen. Voltage is 4.97 / 1.6V for brightness.

Screen is effective i mean it resets the board. Buzzer works along with rotary encoder. Its just dim black boxes.

And X axis still not working after i switched the driver i guess it has some board damage. Any suggestion which line might got damage after wrong connection of driver?


Btw i tested all functios over usb with pc as my screen isnt working anymore. Bed nozzle eyz axises everything works. I switched x axis stepper to y driver stepper is ok as well. Only board left that can be a problem.

Hi.


It is not pleasant what happened to you.
And in addition, I have one more bad news for you.

Your mistake caused at least the destruction of the main µC.

If you feel strong you can try to replace the µC. But the controller board will need to check a few more components.
Also purchase a new stepstick module.

Otherwise, you can write to your dealer asking them to replace the controller board. If it refuses, only the purchase of a new controller remains.

I greet you cordially. Be more careful.

Kaktus's suggest is correct.
I suggest you replace it to the new motherboard.
