  1. I was trying to update the firmware. I purchased a new motherboard with a boot loader and everything is working great until I try to connect the computer to upgrade it.
  2. I have the ender 3 pro and I am trying to upgrade the firmware. I have installed Cura and added the printer, but when I try to select the upgrade firmware button it says it is not connected to the printer. I've tried activating the printer, but nothing seems to happen. Help?
