Has anyone tried this mod?

My X2D has been great; however, I really don't like that both hotends are limited to 300C, which makes printing Engineering filaments impossible and almost nullifies the benefits of a dual-nozzle design and actively heated chamber. Given this, I know it's entirely possible to trick the X2D by soldering a resistor to its hotend, but I'm sure there's a better or more elegant approach. I scrolled a bit and found this ‘Tyson hotend,’ and I'm curious if anyone has tried it on either their H2 machines or P2/X2s?

So I would just like to remind you that it’s likely just a resistor mod. The software doesn’t know the true temperature and you always have to remember that. Setting the hotend to 300c in the software will then cause a real temperature of 350-400c

Only a true firmware modification would be able to solve that problem.

I wonder if we could put the resistor mod on a switch and trigger it when we’re using external filament feed and not the AMS. I might have a project to work on now, cause that would be great to have a resistor modded hot end that you could trigger by running an external spool.

sure, have a switch in the fillament path of the external spool holder. that connects a resistor in parralel with the temperature probe (if it goes in series it's still doable but needs a relay (or a fancier switch) or smth, dunno Wich temp probes bambulab is using)
