Describe your issue:

I have successflly flashed the bootloader using this method found here As I was trying to put Marlin on it but the parts fan never worked, so I decided to come to klipper. I have installed the firmware onto the board useing avrdude as per the printer.cfg file with the changed serial number, but the LCD doesnt work. And what I mean by that is there is no text on the 4 lines, I see on line 1 and 3 the blocks of pixels for characters (and no the constrast isnt turned up too much) any ideas The only thing I have changed in the menuconfig is the baud rate to 115200, but still upload at 57600

The error messages in your log indicate that the board is not correctly flashed with Klipper.

If you have successfully flashed a bootloader then repeat the flashing process with:

1. Verify that is indeed an atmega2560
2. make distclean && make menuconfig → Select the atmega2560, leave the rest as default
3. Flash with: make flash FLASH_DEVICE=/dev/serial/by-id/usb-MakerBot_Industries_The_Replicator_85633323630351B050C0-if00

Otherwise try

1. Verify that is indeed an atmega2560
2. make distclean && make menuconfig → Select the atmega2560, leave the rest as default
3. Flash with: avrdude -c stk500v2 -p m2560 -P /dev/serial/by-id/usb-MakerBot_Industries_The_Replicator_85633323630351B050C0-if00 -b 57600 -D -U out/klipper.elf.hex

Thanks for that I must of needed a clean or something but the second option worked. I just needed to do a make in between step 2 and 3 now for a test print
