Describe your issue:
mcu: 'mcu" unable to connect errors.
Specifically belive this is related to the firmware not flashing onto the printer. I have tried flashing the board several times and every time the sd card returns with the same .bin file rather than .cur.
Note, i am using a 32 gb micro sd card in a kingston sd card adapter to attempt to flash, as i dont have a regular sd card or way to connect said card to my pc.
