Hello Ken,

Welcome to this community. Have fun with building the printer and your first steps in the 3D printing world.

Just one suggestion: Put your MMU2 aside and build MK3S first. Use it for at least couple month and get some experience first. MMU2 adds complexity to the printer and multi material printing brings sometimes even experienced people to the edge.

I'm new here, I thought I'd say hi. Dear mods, if this isn't the right place to say hi, please let me know. 

My name is Ken, I'm an engineer by trade. I design fixtures, stamping tools, injection molds, design/build/program dedicated machines of various types. I've used 3d printers professionally, mostly for prototype work. I'm really curious with how 3d printers will affect manufacturing in the long run. Since the technology isn't quiet there yet (imo), I wanted to stay on top of things, but it's hard to justify printing stuff just for the sake of printing stuff. 

Luckily for me, I have a 7 year old that really likes figurines of all kinds. So, a little over a week ago I ordered a mk3s kit, mmu2s, and a bunch of rolls of filament. I get to learn about printing, kids get random toys, it's a win for everyone.  I'm excited, looking foreword to building a printer, learning the tricks to make best use of it, and making many modifications for it! 

Hello and welcome to the Prusaforum!

According to experience I would also recommend to print without MMU2 first to get to know the MK3 and its features. Otherwise it could be quite difficult to distinguish if an error is caused by the printer or by MMU2.

Have fun assembling and happy printing!

Welcome, Ken.

A retired engineer here.

I would echo the suggestion to get the base-level MK3S working and get familiar with it before adding the MMU2S.

I also was familiar with 3d printing before getting my own printer, and from experience, there is a specific learning curve with the I3, particularly the flexible PEI build plates.

I've had mine running since February.  I describe it as working properly first-time most-of-the-time for most of the prints I've done.  I do mostly model railroad buildings and accessories, with O scale model railroading being my primary retirement hobby.

RE: Hello!

Thanks for the welcome everyone!

I've been trying to keep anticipation at bay by watching various prusa related vids. There is no shortage of people wanting to take a hammer to their MMU, although it seems like some of those problems are already fixed, while others are a case of miscommunication between equipment and its operator (It can be really hard to trouble shoot a sort of smart device when you have no idea what it's doing). Having seen that, I figured that putting the MMU on from the start was probably the wrong way to go. 

Honestly, the greatest thing I wanted from the MMU is the one thing it can't (officially) do, and that's mix flexible and hard materials. I really wanted to build in various hinges. 

For the most part, printers have been chasing after more conventional manufacturing techniques. They will never match injection molding in terms of speed, and still have a ways to go in terms of accuracy and material properties (But they are getting better! That's exciting). I've been wondering what problems a printer can tackle that would tip the scales in it's favor. Some more expensive machines lay in CF filaments for strength. I keep wondering about using something similar and combining it with a rudimentary pick and place machine. If one could print enclosures with built in wiring housings and connectors, that could be a significant game changer. Heck, just imagine the potential of having the head drop in nuts in pockets, and then printing over them for a fully captive nut. 

Well, those are dreams. But aside from compulsively checking my order status, what else am I supposed to do?
