I am in the process of building an MP3DP and at the moment I am testing all of my components to get things in a working state and to understand how all of this actually works.
Last night I was testing the LCD, which is a Full Graphic Smart Controller, and on power on I noted that it had two rows of pixels separated by a 3-pixel gap. I didn’t think anything of it until the firmware was loaded and I was missing detail.
My setup is a TriGorilla ramps board running marlin 1.1.9 and I have set:
It doesn’t appear to be broken pixels as the ones that are not displaying move around, you can see some are active in the second pic, but that may just be my wishful thinking.
Just wondering if anyone else here has seen behavior like this, any ideas welcome, I am completely new to this so its likely something I have mucked up.
