Hi, So I've upgraded my UM2 with the UM extrusion upgrade kit making it a UM2+. The final step of the install manual states you must update firmware or risk permanent damage to the machine. The problem I have is the printer connects to Cura 2.6.1 (COM3) but I'm not able to complete a firmware update. The manual states "install default firmware" however this option does not exist in Cura 2.6.1 so I'm instead navigating to Preferences -> Printers -> Ultimaker 2+ -> Upgrade Firmware.
