Printing PCCF with standard Prusa 4s CHF nozzle?
I want to print some spare parts for the MK4s, more in particular the fan shroud, reports bubble up about it breaking. Prusa recommends PCCF. Can I print that with the standard nozzle that came with the kit?
RE: Printing PCCF with standard Prusa 4s CHF nozzle?
PC-CF is abrasive and will damage a brass nozzle. That said, one small print probably wouldn't be an issue, but any length of time printing PC-CF with a brass nozzle will enlarge/distort the nozzle opening. You really want a hardened steel nozzle for any CF filled filament.

What @ScottW said, but hardened steel isn't the only solution.
Some people swear by the DiamondBack nozzles (I don't have any so I don't have any opinion). There are also ruby tipped nozzles (which can be fragile, I also don't have any). I personally use a Tungsten Carbide nozzle (mine is from Spool3D in Canada, 3D Maker Engineering has a similar nozzle), but you must swap out your aluminum heater block for a copper (or plated copper) one or risk thermal cycling loosening the nozzle over time.
