I strongly advise against buying a Prusa XL or Prusament PCCF.
I recommend NOT buying the XL or Prusament PCCF in 2026. I am an experienced 3D printer, having started in 2016 with an Original Prusa i3 MK1. I bought two rolls of PCCF for my XL and have gotten ZERO successful prints out of that 220 dollar investment.
Updated firmware. Downgraded firmware. Upgraded firmware. Printed mods. Removed mods. Enclosure. No enclosure. Glue, no glue, stock settings, tweaked settings, firmware errors, parking issues, dropped support for my 5000 dollar printer. Clog after clog, multiple nozzles, large, small, stock. HF, not HF, hardened and not hardened.
Support for the XL: Zero
"Flagship status" claim: Completely superseded.
Today, it clogged while I was at work on an 8 hour print. I came home, fixed it. Thirty minutes later, I had a giant PC blob of death, ruining the hotend, the print, and finally, my relationship with Prusa. 2016-2026. I'm done. This printer sucks. Mine hasn't worked reliably since 2023, and in 2026 (eons of time, per many people on this forum), it still doesn't work.
I owned ten MK3S/+. I brought one to Antarctica. They were great. I strongly support Prusa's open source ethos. I cannot condone the lack of support for this printer.
The abandonment of the platform was the first straw. The realization that, yet again, I cannot get my 5k printer to work after following all troubleshooting, after a decade of successful printing on Prusa's platforms, was in fact the final straw. If yours works, good - I am very glad for you and hope you get many more great prints out of it. Mine doesn't.

Prusa XL works great with PCCF. Here is a video proving this : https://youtube.com/shorts/Mo1_dUc9gRE?si=ZiBGgAtw2VrDvWbc

I was really curious to see your successful print since i have problem on mine even with plain asa. I have the faux enclosure that prusa sells and when i manage to print without the heatbed overheat messages it still warps. But to be honest if i print something like yours , round and small stuff it will probably print ok even with the enclosure door open (this is the only way my ~5k printer will print with out the overheat problems). Did you print a bit larger (at least taking 1/3 of the heatbed) and with sharper corners? If yes did you use the default settings. Also i noticed you dont have an enclosure. You have no warping issues?
RE: I strongly advise against buying a Prusa XL or Prusament PCCF.
I don't understand your description of the problem, because PCCF is the best filament Prusa has ever developed. It's as easy to print as if it were PLA.
I didn't have to adjust the filament settings for PCCF.
My Prusa XL has been fitted with a side chain drive, and all the parts are made of PCCF—Prusa XL plus PCCF = a great combination
Mods for Core One: Core One HT 450 degrees, Comfortable display , Very fast print start and Reducing noises
Mods for Prusa XL: Very fast print start

Agree with @jan.d.slay. Prusament PCCF I would even consider be a “beginners” filament since it’s so easy to print. As long as the parts are not too big, I never had issues printing it on an open MK4. Even after mostly moving to a H2D I still buy this filament because it’s great all-purpose filament for heat-resistant structural parts. The only negative is it’s pretty expensive at $85/kg (for me)
That said, I would print it with a 0.6mm nozzle to avoid clogs if you are printing something large. It also seems to me to be a bed adhesion issue.

Concur. The poster is poorly informed.

I have been printing it for over a year, and I am also quite satisfied.

100% concur.

here is how Prusa XL prints a fan shroud in PCCF, no enclosure: https://www.youtube.com/shorts/OFpyw79JG7A
