I have an Anycubic Chiron with a Trigorilla controller board with a chip labeled "ATmega2560 16U TW 355e3f 1833amw" - However I could not find a link to the board, and there is no more info than "Trigorilla" on it. Hopefully it is enough information for you.
Power supply seems to work fine - green LED on, fan on.
The middle piece has a red LED labeled "DC" in red.
Now my problem is that the board seems to not work. I just installed it. You can see all connections on the photos, I made sure to get every angle.
The display does not light up. My connected PC does not recognize an USB input either. I have installed the driver of the printer on the official Anycubic website prior to testing. I have not restarted my computer though - but the display should light up anyway, I figured.
Hopefully this is sufficient information. In case anyone read this, and wants to help out, it would be very deeply appreciated.
