Thanks for providing all this info on the ER20.

I have an issue though, when compiling my own firmware, or using your pre-compiled .bin, I get a blank screen on bootup after resetting the EEPROM.

Flashing the stock firmware again fixes it. Did this happen to you at all?

    this did not happen to me. I will look into it in a week or so and provide a fixed version if i can identify the error. Currently running klipper on the er20 😉
