After cleaning the hot end with the brass brush you should instruct to unload the filament before cooling down. Because the next step is to reheat the hot end and unload filament. May as well do that while it's hot.
This upgrade has been out for 8+ months. How come the instructions have STILL not been upgraded to include how to handle a MK4 in an enclosure? It makes it seem like you are not supporting your customers. Not everyone is a tinkerer and knows how to do this - many of us need good instructions.
Thanks for your feedback, and sorry for the confusion. The main upgrade guide doesn’t directly cover using the MK4 in an enclosure, but we do have separate instructions specifically for that https://help.prusa3d.com/product/enclosure.
Honestly this is just not good enough, I ran into the exact same issue and I had to use google to find a solution.
You have a dedicated MMU3 section and you mention the enclosure ONCE, why isn't it possible to mention that you need to print two parts (a heads up would have been soooo useful!) OR even better, just include them in the upgrade. Imagine my face once I realized that I can't just attach the new LCD Holder on my enclosure...
Having the MMU3 leaves a whole bag of useless Nextruder parts, you could have thrown in 2 Glaxay PETG parts for the enclosure as well and instruct how to install it.
I love Prusa, but I always have to take extra care of use cases which should be common. The same annoying experience I had with building MK4 + Enclosure + MMU all at once.
And also the Enclosure itself with the addons and you have to jump back and forth and look for the right parts.
It just seems a waste of customer time to follow one manual and then break everything apart and follow the 2nd one. :(
It is really bad joke, that the new MK4S display holder cannot be used with encloser - it is too high and the door cannot be closed. No mention in the instruction, this surprise came whern all is ready and I wanted to put the printer back to encloser. Kde udělali soudruzi od Průši chybu ??? Really shame
Yes, thanks. However it makes me upset, this surprise. I promised to my colleagues to have everything ready today - and the only last step to put the printer back to encloser.... there is no excuse for Prusa.
Honestly: there's no excuse for someone making a promise without checking everything and THEN blaming someone else. I think, it's called "claiming resposibilitiy for our actions".
On the Original Prusa MK3.9S page (prusa.io/mk39s), the links to the Assembly Instructions are reversed. The link for the Original Prusa MK4/MK3.9 to MK4S/MK3.9S upgrade take you to the instructions for the Original Prusa i3 MK3/MK3S/MK3S+ to MK4S/MK3.9S upgrade
If you want the whole X-carriage to be PCCF, print out the x-carriage and main-plate* before starting. The x-carriage-back, x-carriage-cable-holder, x-carriage-cable-holder-cover, and x-carriage-clip are also left as PETG. But all of those parts can be easily removed and replaced individually. Only the x-carriage and main-plate require you dissasemble multiple parts. * The MMU3 comes with a main-plate printed from a MJF printer. So you can skip the main-plate if you plan on getting a MMU3 or already have one.
You may want to print out the Y-belt-idler if you plan on replacing that too. The new LCD holder is really frustrating to remove and blocks the screws you use to remove the Y-belt-idler.

Hello. You can print the adapters for the new xLCD cover to use it with the enclosure: https://www.printables.com/model/251931-enclosure-printable-parts/files
The links work perfectly. Thanks for the feedback!
