Got it working!

Much quieter and the motors dont get to warm.

Message me if your still needed help with the right firmware for the 2208's!

Really wish you got an answer to this post as I am trying to find a working FW as well.

I believe you need a Marlin 2.0 based FW to support defining the driver to a TMC2208

Hey all. I ordered a new motherboard for a a20m that failed after only 4 months. It was placed on jan 19th and still states proceessing. Emailed 3 times with no answer.

I feel as if this printer was a waste of money and time so beware being drawn in to cheap dual filament as it never even worked ...

I went to post this exact same issue. While cleaning the hotend the system just stopped displaying anything but i could hear it on.

Taking it apart if find i have the exact same light on and hope to get a replacement gt2560 board from support thanks to your post!
