Hi! I have problem with my new Big-Box - I got error Err: MaxTemp and nothing happen if I try to press my LCD button - is that normal that settings are not available in this error case and what I should double check? This was first start so I there is something wrong in settings. How I can debug this better. It is hard to know where is problem because I have dual. I am very familiar with 3D printers and I have good multimeter/oscilloscope , but I am not sure what are normal resistances in all cables.
