RE: Extremely disappointed with MMU2S
I printed a three blade wind turbine design and was a bit stupefied by the blades. Nothing seemed to provide any semblance of a nice print. In the end, I had to very carefully align the leading edge parallel to the bed and the chord to the vertical axis (took about an hour using hacker tools).
Very painful and tedious work, but I finally got a fair print of the blades.

RE: Extremely disappointed with MMU2S
As for HP and patents and things to come... once upon a time there was this phase change printer tech that had a lot of innovation, allowed a fair ability to mix a wide color palette from three or four, on the fly, and did so without dithering. It yielded high resolution color without needing sub mil print heads.
The technology might have applications in the 3D print world, but pretty sure the early patents have expired. It was the 80's when I was tangentially involved - I was working with testing co-developed Seiko ink jet piezo tech while the lab next door was working on the material science for the thermal wax method. But engineers haven't slowed down since the Phaser started production. There are probably lots of new ways to spit solids at fast rates sufficient for what we know as FDM. They just need an application to force production costs down.
Fun stuff.
RE: Extremely disappointed with MMU2S
With all of the talk about politics, I want to make my feeling clear.
I JUST WANT TO LOAD ONE FILAMENT THRU MY MMU2. If I can't get that, you can't get multimaterial printing to work either. The filament keeps getting hung on the load to the chimney, unless I move it to the right. Then.... guess what. It FAILS because the sensor is triggered at that point. It's almost midnight here, after spending two whole days on it, and I'm about ready to give up. This could have been a slick chamfered funnel to the bondtechs, but NO... It wasn't.

Look through the thread and find the changed files people are using from Thingiverse - they make a large difference.

Right now, I have no printer that is working... thanks to this botched upgrade....
So.... care to print me one of these modified things? I have paypal. LOL... Just sayin I'll pay.

Just turn off the machine, unplug the connector going to the mmu main board, and unplug the tube going into the hot end from the mmu.
When you turn the machine back on, it will not know there is an mmu available to it and it'll run just like a did prior to you installing the mmu.
RE: Extremely disappointed with MMU2S
Oh, great, $300 MMU2 down the tube then... I think I should have got a Chinese printer at this rate. THEY seem to be happy.
Well I guess that's to be expected, because when I reach out to support (Shane), I get nothing but snark and mockery. Just obvious questions that every MMU2/MK3 owner should know... and yeah, snark and mockery. Such as... questioning if I put the MK2.5 firmware on it... PrusaSlicer/Slic3r won't even LET you do that....
I give up. I've had criticism about how things were handled, but this takes the cake.
I am loading this in my car tomorrow and throwing it in a lake. Maybe it can be an artificial coral reef and be more useful to the fish... or some junk like that... 😒

You can return it to Prusa, they offered to pay for shipping back and refund my money. I put so much time into assembly and trying to make it work, I'm still not giving up. But shame on Prusa thinking this is something they could legitimately sell. You can't sell something that doesn't work, well, unless you're Prusa. All that time in beta you'd think they figured it out. Beta testers let them down severely.

RE: Extremely disappointed with MMU2S
Yeah, I was ok with beta, if it were REALLY considered beta.... but they wouldn't have even batted an eye at me. I see how the hobby part of this has evolved over the past few years.
Get this... I even had a nonpology from the guy in support. "I'm sorry if YOU took an attempt at humor...negatively." OH, HA HA joke's on ME!. AHAHAHA! Yeah no. It's not funny when you spend good money and time, on something that has given you headaches..... then deal with snark in support for it.
I've been working multiple angles/positions in contact center outsourcing, and they seem to be checking the boxes on what NOT to do in a customer experience (cx) to keep customers. I'm not even excited about the SL1. I'm more skeptical, given past three experiences with Prusa... I'm tempted to say, I'd be less shy about buying a Wanhao SLA machine after this, than buying a Prusa... lol
Yeah I'm salty.
RE: Extremely disappointed with MMU2S
Cool down for a moment for the sake of your own health!
Yes, PR is selling Beta releases (IMO Alfa releases) as Final for the moment!
Don't buy a MMU2(s) if you need a ready to go solution.
It's just as simple as it is!
They (PR) are pushing their luck to the limit, wrong bed IMHO
The problem is the same over and over again, having a brilliant idea and pasion is not the same as running a successful business.
Josef Prûsa is one hell of a mechanical engineer, now thinking he is able to run a multinational company....
That's an entire different story! But his biggest problem will be to do a step down (forward to my opinion) to become the CTO of his own company and leave running a business to others.
You don't believe me? Look at Steve Jobs and Elon Musk..... poor guys......

You do realize you just gave up when I told you how to greatly improve things, right?
Seriously, spending the five seconds it takes to pull a plug off of a motherboard is all you need to do to suddenly be back to where you were before.
Oh sure, if you have the mmu mounted you'll have to figure out another creative way to get your filament into the hot end without going through the NMU. But that should not really even be a challenge for you.
Once you do that, you can print the parts that will greatly improve your success.
I feel your frustration, but don't let your emotions take over you. This has been a tinker's craft since the start, do a little tinkering. When you're done, you'll have the ability to say you won.
