Hi - I messed up a firmware update and want to change it back. Originally things worked using 115200. Now the printer is using 250000 and I cannot figure out how to change the baud rate in cura. I have the .hex file for my printer. If there is another way for me to upload it to my printer to bring it back to the way it was without using Cura, I am open to that too. Thank you
