HT hotend for XL? Why not?
The 400 degree C HT hotend is offered for the Core and Core L.
Why isn't it offered for the XL? It uses the same regular hotend, right?
I'd be interested in the HT hotend even for lower temperature printing if it heats up faster.
RE: HT hotend for XL? Why not?
Why not? Sadly, it's because they don't care about the XL and have completely abandoned it.
RE:
Because it does not have a proper enclosure and dry box (from Prusa itself), it does not make sense to have a high temp extruder.

So my XL has an original Prusa enclosure, that only costs €619, isn't that right?

My assumption is that the HT hotend is higher-powered and therefor heats up faster than the stock one.
Also, there are some filaments (like PET (no G)) that require high nozzle temperatures but not an enclosure.
If the HT hotend will work in an XL, Prusa should say so.
What we end-users do with that knowledge shouldn't be a concern.
Also, FYI, my XL has both a Prusa enclosure and a two-spool filament dryer feeding hotends 4 and 5.
RE: HT hotend for XL? Why not?
Another vote to support an HT hotend on the XL. I would purchase at least two for my 5T. I want to print better engineering filaments that require 350°C.
I've already enclosed my XL, upgraded all PETG parts to PC-CF, and added a fan to the heat bed controller.
RE: HT hotend for XL? Why not?
If you have the PETG motor mounts, this is basically not feasible. The enclosure for our machines is an afterthought, though I like the look. They kind of designed themselves into a corner. We won't be getting a HT toolhead officially.
RE: HT hotend for XL? Why not?
Here, too, I must say that I have been working on implementing a Prusa XL HT for a year.
No, I don't need the Prusa XL to urgently print parts that an industrial printer could also produce. It is my experiment to see what is feasible and what is not.
I will simply bypass the 290 degree limitation with hardware. Software-wise, it is feasible to unlock even higher temperatures, but I am taking a different approach.
This approach involves controlling the nozzle temperature externally via a much more accurate PID control.
