I have the UM2Extened+ and Heat 1 has gone out on the contol board. Can I install the Firmware/software, move the hotend 1 heating cartridge and thermistor to the connections for HEAT2 and extruder1 to extruder2? I will only be able to use extruder2 in Cura, but will it work?
thanks
it depends... on what exactly is broken.
One crucial point:
For security reasons Marlin firmware requires at least a connected temperature sensor for each configured heater (doesn't matter if a heater element is actually connected).

Ultimaker never released a dual extruder UM2 printer since we couldn't get it working as reliable we wanted. All 3D printers with a second nozzle have the problem that the other nozzle can damage your printed object, so special measures have to be taken to avoid that. For example, the UM3 printer changes the height of the second nozzle.
You can download the UM2+ source code and then change the configuration settings to activate the 2nd nozzle, but without mechanical improvements to change the height of the other nozzle your project will never print reliable.
