# Where to find others with Prusa3D i3m3s/MMU2s printer?

I don't want to ask off-topic and opinion questions here, but I would like to find a cadre of others dialing in their devices. Any ideas?

• HI, I migrated the question to meta, I hope that you understand why. :-) BTW, What do you mean by dialing in their devices exactly? Do you mean comparing their printers and posting pix? Or something else? @Starwind has a (large?) Facebook group, he might know more...? I don't have a Facebook account (left it years ago) so I don't know anything about that...

• I thought I had written it on meta. I wonder what I did wrong? It is totally not a main group question.

• @greenline I'm not sure what word is used in the Prusa community. I mean going through the process of tweaking this and that to improve the reliability. There is data in support of the mmu2 being a great addition, but at the moment I have a user interaction rate of about 5-7%. With 100 changes, I have to intervene on about 6 of them.

• @Mick Thanks for the reference to the Facebook group. I'm waiting for a moderator to approve my join request.

I stumbled across this forum/group, Original Prusa i3 MMU2S & MMU2, amongst all of the other Prusa printers forums on the Prusaprinters blog, which seems fairly active.

In particular, the User mods - OctoPrint, enclosures, nozzles, ... page seems like it might be what you are looking for.

There is a lot of activity on Reddit related to 3D printing and the Prusa printers.
