How to print Pc-CF parts like prusa (size dimensions, extrusion multiplier)
Goodday,
I need to print some parts for the nextruder in pc-cf.
I see a lot about extrusion multiplier and not correct dimensions.
Now my question is. Does prusa alter this extrusion multiplier or leave it on stock 1.04?
The parts like idler swivel and idler lever need to be the right size.
But what is the right size? The size from prusaslicer?; or the size coming from the print beds of prusa?
Or the size i have afrer calibrating?
I cannot reverse engineer the bgcode for core one pc-cf parts so i don't know the settings or if the altered the settings.
Thanks in advance.
RE:
The leave it at the stock 1.04. You can open the 3mf file in Prusa Slicer and it will give you the settings they used. The only thing modified from stock appears to be the cooling.
You can get it from here: CORE One printable parts under the Model Files/3MF/PCCF parts.3mf

This is very topical for me since I had a print go horribly wrong and break the fan shroud so I'm printing a new one as I write. The old one is currently patched up with Kapton tape... What is interesting is the parts were setup for printing on a MK4S but that shouldn't really matter. I'm printing right now on a Satin plate with Magigoo PC.

I've printed may Prusa parts with PCCF and just used the standard structural print profile and the default PCCF filament profile. The only change I made was to switch to cubic infill

Did you have problems assembling some parts ?. Unlike PETG, PCCF is very stiff so I'd quessed that, for instance, pushing the smooth rods and the linear bearings into the X carriage would be challenging if you print this part in PCCF. It's already a tight fit if it's made from PETG.
RE:
I've only used Prusa PC-CF for printing spare parts. They've mostly been small (like the belt tensioner pulleys) and I successfully printed the fan shroud which is a medium sized object. Both times I used the satin sheet with Magigoo PC and the stock settings for that filament. No issues with bed adhesion nor dimensional accuracy using the default 1.04 extrusion multiplier.
My suggestion is to not over-think this and just try it out first.

Ok will do. 😁
I have no problems because i don't have it yet. But i don't want to waste it.

Oh you bet. Getting the smooth rods into my "Carbon" Mk4S required some serious conversation with a hammer...

Is that part original in pccf?
then the extrusion must be set to 0.97 or something i think?
RE: How to print Pc-CF parts like prusa (size dimensions, extrusion multiplier)
No, it's not. It's PETG. I just reprint all my printer plastic parts in a different color for each printer, and this one was called "Carbon", so I printed all parts in PCCF (which did make it look supercool). In retrospect I should have printed those parts that hold the rods in PETG.

Those parts have to be slightly flexible and not rigid. An alternative would be Nylon but it's a PITA if you don't anneal it.
