MK4s nozzles ?  

RE: MK4s nozzles ?

Found a probable answer myself where it mentions how to change a nozzle on the Core One. Geez that is a convoluted procedure. I will miss my manual 30 second hand swap op my revo heater in my MK3s...

RE:

MK4S nozzles are compatible with the CoreOne.  They can be swapped fairly easily.  Maybe not as easy as the Revo, but I can swap mine in just a couple of minutes.  Look for the quick change nozzle swap instructions.  Or this… https://www.printables.com/model/980297-mk4s-nozzle-replacement-tool

RE: MK4s nozzles ?

Thanks for the answer. As for the tool, since the X-axis on a Core One is not a rod, I suspect it may not work

RE: MK4s nozzles ?

I had a Chat Session with Prusa Support and got told that right now they're not 100% sure if e.g. the MK4 Obsidian Nozzle will fit the Core One.

In my opinion it should, but that´s what I got told a couple of days ago.

RE:

Update: Since today -at least i found it today- the "E3D Prusa Nozzle: High Flow ObXidian™" has additionally listed the Core One as compatible.

But if you´re look into the Specs and Data you find the Core One in the List "Not compatible".

That´s a bit funny and confusing. Anyways, i ordered them and hopefully Prusa will take them back if they´re in fact not compatible. I´ll find out in March, so god will.

Attached Screenshot shows listed as comp. but in the infos as not comp.

RE: MK4s nozzles ?

I have Obxidian 0.4 standard.  Works fine in my MK4S so I'm confident it'll work when I upgrade to CoreOne.  I avoided the High Flow Obxidian because abrasive materials tend to cause more clogs and the HF nozzles are more vulnerable due to the narrower internal geometry. 

RE: MK4s nozzles ?

Thanks all again for the answers. Wait and see I suppose. I do have the normal / non high flow nozzles

RE: MK4s nozzles ?

All MK4s nozzles will physically fit the Core One considering it is the same extruder - just different heat block and cooling fan arrangement. It should work completely fine. Maybe Prusa need to add the option to the slicer presets etc hence the confusion of whether its compatible or not right now. Either way, it's a software thing so will come soon - but hardware wise, there is nothing stopping any MK4/4s nozzle from working with the Core One.

The most recent PrusaSlicer profiles batch (as of 2025-02-03T11:45:00-5:00 (US-EST)) has profiles for different nozzle sizes in both HF and standard. See my screenshot in https://forum.prusa3d.com/forum/postid/735069/
