RE: New Core One+ with 400C Hot End
PA-CF and PA-GF don't really need super high nozzle or chamber temps and can be annealed afterwards. Same with the PC based materials. For me the 400C hot end opens the door for PPS which I've been wanting print for a while. I also have a roll of PPA-CF but at 290C I can just barely get usable prints from it since I'm using a Diamondback nozzle.
What PPA brand is that? I have tested Sirayatech PPA-CF and it seems to work pretty good (after changing the idler arm), could easily lift a 25kg battery with the CNC kitchen test hook printed in the z axis. Though more temp means even better layer adhesion, MyTechFun did some demonstrations of that on some of the PPA, i just dont remember which video that was. I use the non high flow 0,4 obxidian. PEEK does seem to require alot of work and high chamber temps, but its super niche since it isnt a great alla round material, but has some very unique features. Seems odd to start competing with their pro printers, but on the other hand 400C does make it pretty unique in the consumer world.

Yes, it's Siraya Tech PPA-CF. Their regular PPA is awesome and I print a lot of it. I can print the PPA-CF OK with the diamondback and the bogie mod, just wish I had a bit more temp to work with.
The other plastic that I've been experimenting with is Delrin (POM). This stuff is black magic (if you can get it to print). It only sticks to G10 or G11 print surfaces. It warps like crazy unless the bed and chamber are super hot. This is the wildest filament I've worked with to date. It has an extremely low COF and is indestructible. I plan to do a separate thread on it later.

QIDI PLUS4 3D Printer - 370C hot end and 65C active chamber for 700 USD. Couple this with a tool changer and basically the advanced users are catered to without breaking the bank.
RE: New Core One+ with 400C Hot End
As I've stated elsewhere, I have a Qidi Q2 here at work that I can print reasonably small pure PC parts on, and larger ezPC (a very good PC blend) and FR PC/ABS parts on. The parts with the worst layer adhesion seem to be in FR PC/ABS and I connect that to the ABS qualities. Qidi seems to be already hitting this target market with an actively heated 65c chamber and a nozzle hot enough to do most filaments that can handle such a "cool" chamber as 65c. The next step in the market gets you to either the HT90 or the 22IDEX. Both of those are >$12k.

Unless I am mistaken, E3D just released their version of this nozzle. Why not use this instead?

Prusa even sells it themselves: https://www.prusa3d.com/product/e3d-prusa-nozzle-high-flow-obxidian-500-0-4-mm/

Was about do go that direction from my mk3, but then the C1 was released so bought that instead. I followed the Qidi FB groups for a while and wasnt totally convinced back then, maybe they sorted it out a bit better by now and it has some user tweaks.
Yeah 400C with 55degree chamber is a slightly odd combo, but going high like 340+ish will help with normal high performance materials like PPS.
