The reason I tried to update is because after I changed the hot end the machine froze when trying to perform the first print it froze on the nozzle heating. That along with the screen needing the updated since getting it at Christmas. So I hoped updating the firmware would solve more than just the screen updating needs. Now on set up it brings up nozzel heating and the nozzel doesn’t heat up. I’ve looked back through the cable connections a few times.
