Is the MK4 enclosure ready for the MMU3?

Still missing are a quick connector for the PSU (from Prusa for the MK3S+) and a display quick connector (from the community for the MK3S+). But you can make it work. I don't know if an enclosure assembly manual from Prusa for the MK4 has appeared in the meantime, but I could manage with the manual for the MK3S+.

Any update on this topic? Will the MMU3 fit in the enclosure with the MK4?

RE: MK4 + enclosure + MMU3

I am running an MK4 in an enclosure with the Power supply mounted externally and the display still mounted to the MK4.   

The MMU3 does not change the basic dimensions of the MMU from MMU2.   The MK4 frame is the same dimensions as the MK3s.  They all  fit in an eclosure.  I have some pictures here with the MMU mounted Horizontally in an enclosure.  It takes more height horizontally.   I prefer it horizontal.   I also have squash ball feet on the MK4 which raises it 20mm/0.8".   There would be more top clearance without the squash ball feet. 

If you have not added the lid option for an enclosure, I would suggest you have a lid  on the enclosure when using an MMU.  I drilled a few extra holes in the side and top to side mount  the hinges for my lid.  It opens to the right, not the back. 

As stated, there is no quick disconnect for the MK4 power supply cables yet.  The cables are just long enough to mount the power supply outside.  I modified the MK3s quick disconnect for the MK4 cables.   2 wires change.     The display cable has to be re-routed if you want the display outside.   My display is inside the enclosure.  For me it is safer keeping it protected from people walking by.  Currently no quick disconnect for the display cable.   Disconnecting and reconnecting the 2 MK3s+ display cables was no problem for me.  The MK4 display connector is 1 connector and in my opinion a little more delicate.  I wouldn't want to unplug it too many times.   

The wifi and Prusa link has reduced my interaction with the display.  I hardly ever remove the USB stick.  I can manage and upload files along with starting, stopping and monitoring a print from Prusalink.

Prusa support confirmed that the MMU3 is compatible with the MK4 and Prusa Enclosure. You can follow the steps described in the "Hinged Lid" addon assembly guide: https://help.prusa3d.com/guide/6-hinged-lid-add-on_354154 (Support confirmed as well that steps are the same, even though it shows the MMU2S with an Original Prusa I3).

They also told me that the assembly guide for the MK4 together with the MMU3 & Enclosure is work in progress.

I have the Enclosure with all addons and the MK4 as well - very keen to try out the MMU3 later on, since my kids want multi colored toys 😉

does anyone know if the mk4 and mmu3 will work with the Ikea lack enclosure in the same way the mmu2 did?

RE: MK4 + enclosure + MMU3

Hi,

no, I wait for my Upgrade-Kits. But I work on the Printing Parts. Some Parts make I with PA12 with SLS Printing. This was good at MMU2 and  I think, at MMU3 is this not a mistake. The Idler and Idler Body and the Selektor became a PA12 SLS finish. The rest of the parts are Standard - the Elo will I modifiy like MMU2s, to reduce the sensor-cable - i don´t like the orginal way to stretch and push... I´ve seen, that they now use Push fittings to hold the 5 Bowden Tubes - like I has modified my MMU2s - I thought, i must change it another one, but they heard us User, that this is terrible - if one must be changed and has not the exactly outer Perimeters, the troubles began... The reason, I changed the completly body of my MMU2s to M10 Push Fittings with no Push Plate for the Tubes and Selector-Part with no bottom, that cuted Parts can not blockade the Selektor... There is a peel between the MMU-holders.

But, if I look at the print parts, I wonder why you think it should work differently - other than better? 😉 I see nothing, what will be make problems... But let me know, If you found anything... Sorry, for my worst english, but I hope, you understand me...

Can anyone post a pic of their MK4 + MMU3 + Enclosure? Trying to get a "real world feel" of the footprint / space it'll require with multiple spools in place, etc.

 

Thanks,

I just put together my MK4 with the enclosure and I'm already eyeing the MMU3. There seems to be plenty of space above the printer in the enclosure. Can someone confirm that it works? Does it need the hinged lid and/or quick release PSU addons?

The MK4/Enclosure/MMU3 will play nice together once the MMU3 for the MK4/3.9 is available.

The hinged lid will make working on the MMU3 at lot easier due to the improved access.

The MK4 PSU quick release is nice but not required.  

I would consider the LED lighting if you don't have it.  It makes seeing the prints and working on the printer easier when you can see it.

RE: MK4 + enclosure + MMU3

I was under the impression that it was already available :'(

Yes, I was printing today with a black filament and I could barely see it. I will definitely want an LED strip there.

I don't really understand why it needs a separate power supply with a separate power cord, it seems like a very hacky solution. One power supply should easily be able to handle the small amount of current needed for the LED strip :S
