Prusa is working again
@GHunter The idea was to put the printer on top, spools underneath. The cart would normally be parked in the hack room where the computer by the door currently sits. Mobile was to allow it to sometimes go to the classroom.
I was looking at Prusa’s site some more on the weekend. MMU has been superseded by MMU 2.0… Which addresses most of my trouble with MMU.
But, the MK2.5 upgrade kit has also been updated. It is no longer MMU 1.0 compatible. As an MMU owner, we can get MMU 2.0 for $150. (Normally $250), then the upgrade kit is another $200. One of my coworkers has the new Prusa with MMU 2.0 I think, so we could likely get an idea of how much it has improved from him.
Alternatively, I can get(likely a knockoff of) just the heated bed part directly from china for about a hundred bucks:
So, whad do you guys want to do?
Personally I’d rather see the Prusa returned to its original single extruder state.
Given the choice between a consistent and reliable 3D printer or multi-materials I’d choose consistency. Since the MMU was installed I have struggled a LOT to get a good print out. Granted I’m a novice user, as such I just want something that works. I’d expect most people who are new to makerspace would feel the same way.
I talked to my cow-orker about his system. He has the MK3, and
has not added the MMU yet. He’s planning on doing so at some
point. In theory, MMU 2.0 addresses the reliability issues of MMU
1.0, and returns the system to a state that should be as reliable
as the original single-extruder. I’ve got a MMU 1.0 system
myself (not installed, but I bought one at one point…) So I
have the option of doing the $150 2.0 upgrade. He’s willing to
get the 2.0 kit using my discount, and we can see how reliable it
is relative to the single extruder system.
I think the focus should be on getting the printer back to full functionality, which means upgrading the bed.
The Aliexpress bed looks good! I’m all for it
The sooner the better
OK so if @JasonH is chipping in $50 and I am chipping in $50 then the print bed upgrade is paid for for all intents and purposes.
Anything I can do on my end to get that thing fixed lemme know.
I managed to get some use out of it last weekend even printing in the corner a couple small pieces were a challenge, but a big print with a substantial raft was doable.
Do most people want the Prusa rolled back to single material? That has nothing to do with print adhesion but if there are other issues with the slicer that may be the answer.
We should also consider cleaning filament. https://rigid.ink/blogs/news/how-to-use-3d-printer-cleaning-filament
@GHunter which link are you referring to? The link on page 1 is to Prusa and is for $200 USD, so at least $300 Canuckistanian Imperial Credits when you also include shipping. I can’t spot another link, but that may be because I’m still working on my first coffee…
@Torren this one, just the print bed upgrade looks like AliExpress has a range on pricing and then shipping too, but $25 to $40 is achievable depending on patience levels. @pierre do you have an account for aliexpress for firm pricing?
@Grant-Fraser that cleaning filament looks awesome. I would call that a “must have” for the space.
I’ve stated my opinion on the multimaterial. That said, keeping a spool of the cleaner always queued up in one extruder so that a user could run a cleaning routine g-code before a major print session? That would be wizard.

The pricing on aliexpress is firm. there are two options. I would go with the second one.
@GHunter The cleaning filament is horribly expensive. you only want to use 10 cm at a time. Its.$20 per 100 grams on Amazon so a spool would be $200. Someone might try to print with it.
@Grant-Fraser Ah yeah maybe not a spool.
These guys at filament.ca sell their house brand for $9 for 3 meters, shipping is only about a buck since they can just stuff it into an evelope and snail mail it to ya.
Actually looking closer at the Amazon listing a guy reviewing it figures the 100g is about 143ft (43m) , meaning you can get 430 uses out of it. Pretty damn good for $20, and better than the short filament.ca length.
