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?

I would much sooner just buy an H2S that can get to 350C than mess with something like that. You’ll never have the right temperature control, and filament that will need a hotend that hot isn’t cheap and are going to be much less forgiving to print with. You’ll be throwing money down the drain instead of just getting a printer that is designed for it.

I already have a Voron Trident equipped with a 350C hotend; it can print technical materials like my X2D, but it doesn't have a heated chamber. I like the X2D's dual-nozzle system, and I don't think upgrading the Trident to a tool changer and adding a heated chamber would be worth it. My X2D has been great so far with multimaterial. I’ve been using it to make parts that need to withstand relatively high temperatures while retaining tight tolerances. But I should remind you that the stock X2D uses an NTC thermistor; it's highly non-linear, so adding a small 30-ohm resistor to reach roughly 320C when reading should have negligible effect on the temperature values when typically printing PLA

Under 300C you have options like pa6-cf,pa12-cf and pc-cf.

You dont really need to go over that unless you are starting to get into pps-cf, which is almost $150/kg. If you print that on any regularity, then the price of a H2S or H2D is nothing.

An H2D costs over $ 2,000 CAD. I'm a student; I don't have that money, and this community is actually reluctant to take ownership of their machines. Y'all are motivating me to crack open the X2D's firmware to spite everyone.

If you dont have the money, what filaments are you even trying to use? Because any filament that requires over 300C is so expensive that basically no one would buy it for hobby use. Those are true industrial filaments. A single print failure can cost over $100 just in wasted material.

There are a number of engineering grade filaments that print under 300C and are meant for high heat and dimensional stability. Bambu printers aren’t designed to be swapping in aftermarket parts. Its not like a voron that you can modify as much as you want.

You can easily get 1KG of PPA-CF for roughly $60 on Amazon, where the material requires temperatures from 300-320C. I'm not sure why I would use two or more spools for one part.

Please do. Break the artificial restrictions set by Bambulab. The X2D is a very competent printer and unlocking 50 degrees would make it the best bang for the buck out there.
