MMU2s delays  

Re: MMU2s delays

I worked/work/working in production for around 30 years and ramping up production is harder than you think. There are vendor issues and some parts could have lead times of a year or more (probably not Prusa's case). Hiring new people has issues with getting them trained up. I have seen new hires destroy months of productions and sometimes you don't know until the returns start showing up so you don't know for months that they did something wrong.
I would say their biggest problem is they pre-sold a product that didn't quiet work right and kept taking orders and stopped shipping and kept taking orders and now the backlog is huge and they just can't make them fast enough while insuring quality. I have literally been on a production floor at the end of the quarter when management says to ship everything to meet their numbers and they will deal with the returns. 😮 You never want that to happen but as one production manager once told me. "If we don't ship and hit our numbers I don't get my bonus" 😯
I think Prusa should have stopped taking orders because it just damages their brand.
Good luck and hopefully you get it soon.

funny you should say that. I got my mmu2 in the last batch before they decided to halt and move to mmu2s.

And I have to say:
(1) the prints... oh the prints. I've had to set my heat gun to nearly every one. The stringing on the prusa provided parts for my mmu2 are unbelievable. Saying they rushed it and lowered their standards is spot on.
(2) the ptfe tubes for the mmu2 filament feeder thing.. there should have been 5 in the kit.. but there were only 2! (what?! if there were 4, i could understand a little human error... but 2/5 is not even close).
(3) they replaced the ptfe tube.. but rather than send 3 little cut and ready to go tubes... they sent me 4 massive uncut long 30cm long ptfe tubes. handy etc. but I'd rather have had them pre-cut and ready to go in. They must have hundreds of the damn things in a bucket ready to go into Kits.. right? hmmm.

it all smacks of blue-arsed-fly-edness. I suspect they're installing in-floored cooling to help with the heat generated from the friction of shoes running around flat out in every direction at 100km/h, 24/7.

In that case, they sent you the wrong tubing. Possibly with incorrect ID.

I worked on production floors and unless they have a formal way of fulfilling requests it is a game of Telephone and the person pulling the actual parts are six degrees of separation from your message asking for "5 ptfe tubes 10 cm long" they get the message "Blue birds only eat OREO's after midnight" and they are in a rush to do their real job and they shove something in a box to make the request go away so they can bang out 40 widgets a day because that is their daily quota.
Also a small percentage of people are just hung over in the morning and are barely functional and they tend to gravitate to warehouse work. (Worked in warehouses and know this for a fact)

Interesting. I also received mine from the last batch sent out before the S was reveled (they announced it the day after mine left the factory). My Prusa printed parts are spot on with great fit and finish. However, I also only received 2 of the short feeder ptfe tubes. It appears that happened to quite a few of the last batch out. When they sent the replacements, I received a little ziplock plastic envelope with 5 cut tubes in it. So sounds like you really lucked out - in the bad sense.

Re: MMU2s delays

That may be the case but I'm paying interest on the charges on my card and wont even receive the product for 6 months.

A key part of of this has always been you have the product ready before you announce. NVidia has screwed that up so many times and it has cost them dearly. This continues to be a major problem with companies that just dont get that you want to announce and be ready for the orders otherwise you look really bad with customers not being able to get the product you just announced.

Counterpoint: You don't want to stock up too much and be left sitting on a pile of useless stock if (when?) a product flops.

Re: MMU2s delays

I ordered my MMU in November 2018. The expected delivery date is beginning of February.
Since the release of the S version, the time of the anticipated delivery is extended cyclically. For last two months, the delay has been always for 4-5 weeks. I do not know if they will make it this year.
Of course, zero messages. That's how Prusa corp. works.

Re: MMU2s delays

For what it's worth, I ordered mine on 9/26 and received the tracking number today. I'm in the US.

May be a counterpoint, but terrible business strategy. "I know, let's not manufacture hardly any of a product we just announced, just in case it's a flop". LOL. It's called market research and due diligence, which should occur well before you spend a lot of time and effort on a new product.

You're taking what I meant to the extreme. Obviously "hardly any" is just as bad as stockpiling for weeks and having too much. But it's really not logical to speculate without knowing exactly what the internal situation is at PR. There are two sides to each coin, and it's nonsensical to generalize something as a poor business strategy without knowing all the details of the situation in question. There are many businesses where demand may be relatively large, but the product is specialized/made to order for each customer or order volumes fluctuate to extremes - and making excess stock is just wasting money.

(I'm speaking in general terms here, not specifically about PR)

Re: MMU2s delays

I have the impression that usually the announcements are made even before they have an idea how fast they can produce something (if at all - cfr the sheets). For me that reads as "just give us your money, you'll get the product eventually".

And other times it just seems stupid.
I mean: Take this upgrade right. They know they have 7000 MMU2 units in the wild of which - I'm assuming - a large part doesn't work well. So they come out with improvements and offer to give them to everyone for free. Nice gesture, but I mean: It doesn't take a genius to know you're going to get 7000 of those orders right? So perhaps make sure you have the items for at least half of those in stock before you send around the voucher...

Look, I love Prusa products, and in the end they always deliver (or I wouldn't be around here anymore), but that's just really frustrating. I'm pretty sure they already lost a lot of customers because of these kind of things.

You are of course correct, neither you nor I know what goes on at PR. However I think it would be "gobsmacking" to suggest they didn't realise how popular the next gens of their two main products would be, since they already had past sales figures. So your "counter argument" really doesn't apply in this case.

Peace out.

Re: MMU2s delays

I Just got mine last week,(ordered on 8/29/2018) The wait was worth it, so stop complaining. worked perfectly with out issues (I didn't seat the IR wire correctly), when I ordered it it was a MMU2...I got a free Upgrade to MMU2S and My MK# is now an MK3S! talk about awesome service. if you want it now, go to Wally World. Oh yeah they don't have MMU2s's...Make your own, oh yeah you don't have the parts or knowledge. (because you have time to wait, and you had the money when you spent it on it. Trust me...ITS WORTH THE WAIT, so kwitchabitchin . 😆

Sorry, you can't be trusted. 😆 😈

Re: MMU2s delays

A lot of good points and constructive comments. Thank you for not turning this thread in to a flame war as it wasnt intended and much appreciated to the replies.

9 weeks down about 3 weeks before my expected ETA for my MMU2S

Re: MMU2s delays

all this wait just to use a 2nd sensor for the MMU2 just sad.

RE: MMU2s delays

I just received my notification the MMU is on the way!!!!!
