firmware.bin , but when in the wizard I hit "Check board status" it never does anything. I can't get past this screen. I've tried a couple of times, each time the control board is renaming the firmware.bin file to FIRMWARE.CUR. I did a diff and the two files are identical. So the board is picking up the firmware file it appears. But klipper isn't seeing it? In the ui I get an error "mcu 'mc': Unable to connect".
