0.25 nozzle with MMU3 + MK4?

Hi all,

I'm aware that when the MMU3 appeared the only nozzle that could be used with it was the 0.4.

But now, I wonder if it is already approved by Prusa that we can use other nozzles, specially the 0.25, for more detailed text in prints?

Thanks!

You can select 0.25 nozzle in settings-printer-extruder1.  All extruders of course use the same nozzle size.

So that means no more nozzle size restrictions with MMU3? Is it now simple and trouble-free like using another nozzle without the MMU3 installed or are there any cons that I should be aware of?

I remember reading not long ago that one had to add/change some code to be able to use other nozzle dimensions with the MMU3 and some times there was some problems at printing time…

Thanks

I wondering the same thing. I just ordered some .25mm nozzles to use with my MMU3 to try and print some better miniatures and wanted to make sure it will not be a uphill battle every time I try to print.

It looks like no one else has a clear answer to this (?)
