Like the subject line says, I flashed my new A20M to Marlin 2.0 bugfix with Arduino 1.8.10 and now the LCD only display a blank blue illuminated screen. I also loaded U8glib.zip. Any suggestions? Thanks in advance.

Hi, You can try to reload the firmware,
then reconnect the screen cable.
and you can also provide a specific video of the problem
so that we can better solve the problem

Doesn't warrant a video, so how about a picture. Powers on and then blue light. No noise other than fans.

Bumping this up. I really need to get this thing working or find an alternative.

Thank you for your response and for your time spent responding. I really appreciate any assistance you might be able to provide.

Unfortunately, I am not entirely sure what a) "properly define the screen" and b) "flashed a hex with bootloader" mean.

I downloaded arduino 1.8.10 and the bugfix-Marlin 2.0 from mediafire. I had U8glib.zip installed, compiled and then flashed. No errors during compiling or flashing. Just a blue screen when everything was done.

Not sure what my next step should be at this point.

Thanks!

So I went back and followed all of the instructions and of course the screen came back on. Vert you are the man.

Unfortunately, there is another problem. I cannot get the printer to auto home and as a result I cannot get the bed to auto level. I have tried every tutorial and so far nada.

As always, I greatly appreciate any and all assistance.

Best.

I am game. Discord like the gaming chat program?

Hi, You can check if your axis can be moved manually.
Then check that your motor cable is properly connected to the motherboard.
If you can, please provide a specific video so that we can better solve the problem.

Hi, i have the same problem. How can i fix that in detail? Any .hex included bootloader available?
