A10M - first start-up.

[BinhLy]

I just assembled new A10M 2 color mixed printer. I installed driver (anywhere okd) for my MacOS but I can't see the printer via USB. The LCD panel show 2 rows of dark dots and green background. I installed Aguire, Marlin, and Repetier etc but the LCD is still the same. My Mac Book still cannot see the A10M. How and where do you adjust LCD brightness or contrast for the new board? How to make my Mac connect to the printer. I tried CH341 driver for Mac. Didnot work.

Press reset button. Mine is doing that as well.

Idk if it will help but try removing the SD card and pressing the reset button. I noticed every time I powered off and back on I was getting that screen, but only when the SD card was inserted. I started using a brand name as SD card and no longer have the issue
