The Pi3B+ will be fine.    You just install the canvas hub plug-ins  into octoprint and you have a canvas hub.  The link to instructions I posted above has the details

The pro has the heavy duty cutter core , some spare parts you don't get with the non-pro  and a bit longer warranty.  

I think long term the extra cost of the pro will pay off.

Just under stand the Palette isn't perfect.  There are still some quirks with it.

I actually use the Palette mostly with my Taz 5 since I have my MMU2s  working really well.

RE: First thing I do tomorrow is remove the MMU2

While I do realize there is a LOT of extra work to get the MMU2S working right (it's so dependent on your setup: things like precision of parts, from where you are loading filament, what kinds of filament, etc.), after weeks I finally got mine working right. And in single filament mode, it works like a MK3S for me.

Many times though, I will just completely bypass the MMU2S by using the underslung panel mod ( https://www.thingiverse.com/thing:3211711 ) and horizontal mounting bracket ( https://www.thingiverse.com/thing:3286954 ) (makes it VERY easy to do maintenance work on it) and removing the power cable and feeding in the filament directly into the extruder. Just wanted to point out this is an option for everyone until they have the time to get their unit working properly, especially right now with everyone wanting to print PPE to support their community.

I would not recommend the Palette to most unless you're going to be doing a lot of multi material prints because it's just insanely expensive and from what I understand, they force you to use their cloud (non open source) software. 

RE: First thing I do tomorrow is remove the MMU2

^^ Really, Palette forces you to use their cloud and feed all your build data through their cloud? I did not know. I was also having a look into the system but that aspect makes it just a no-go for me.

Is there somewhere a good comparison between the pros and cons of MMU2s and the newest Pallete (or Pallete Pro)? I mean especially also regarding the quirks and issues as well as material efficiency, speed etc.

RE: First thing I do tomorrow is remove the MMU2

If you use their program CANVAS, it's an online app that crunches the numbers in the cloud ... I believe.  I don't think it's mandatory that you use CANVAS though.  At least that's the way I understood it when I watched their video.

They are really pushing CANVAS for all Palette 2/2S/+ models. Chroma (their offline solution) is a pain and requires a lengthy two step process to customize your slicer of choice so you can output proper gcode that Chroma can process (see https://support.mosaicmfg.com/hc/en-us/articles/360012415733-Chroma-for-Palette-2 ). It's also missing a lot of the newer CANVAS features. There are many discussions here that compare Palette vs MMU. Don't expect Palette to solve all your problems; it also has its limitations. At least with the MMU, you have the option of fixing it yourself with the right mods.

RE: First thing I do tomorrow is remove the MMU2

That's also what I was thinking. The MMU is tricky but it is super accessible to modding and the most useful mods can be simply downloaded and printed without much effort.

RE: First thing I do tomorrow is remove the MMU2

Keep in mind, Mosaic is charging $125+ for the "upgrade kit" to make the Palette 2 work like it should have in the first place (and yet it still has issues). Really? As if paying $499 for the basic Palette 2 wasn't enough? You really want to support a company like that? And then another $140 for CANVAS hub which is a glorified Raspberry Pi Zero (10 bux) running Octoprint (free)!? Even though Prusa also charges for "official" upgrade kits, they open source all their designs so you can do with it whatever you wish.

Again, you can make the MMU2S work ... there are a LOT more people that will complain about it here than others who are happy with it and will not bother to post. I look at it as an enhancement to my MK3S; even if I don't need multi material (and I usually don't), I automatically get features like spooljoiner that will trigger the next filament when the current one runs out, which has been awesome for printing PPE since people don't care about aesthetics there.

RE: First thing I do tomorrow is remove the MMU2

I really don't know Pallete that well but what you are saying doesn't really make it look all that attractive. Regarding the MMU, there is nothing wrong with it. People who have ever looked at the forum are aware that you might need to tune in the system befor it starts working reliably (or at least reliably enough). I think mine is now working fine and the results are great.

It is never wrong however to know the alternatives on the market.

RE: First thing I do tomorrow is remove the MMU2

You don't need to tune MMu2, you need to re-engineer it. It will cost time, frustation, and a lot of filament.

RE: First thing I do tomorrow is remove the MMU2

I fall into the "it works for me" camp. I got mine last Aug and while I also do not do many multimaterial prints, the ones I have done have needed little, if any intervention after the initial rounds of figuring out things like filament supply friction and sensor adjustments.

I don't debate that people have issues with it, but I'm just posting the under-represented data point of satisfied users that don't have much of a reason to post about it working as expected.

RE: First thing I do tomorrow is remove the MMU2

Just an update because I see some activity here.....

I took my MMU2 off my machine and decided the Pallet was going to be my frustration of choice. I will tell you that each has pros and cons and each can be super satisfying and super frustrating at the same time. Here are some of my bullet points:

• MMU2 came off and even knowing I didn't need to revert back to the original setup, I did.
• I have the Canvas but it basically transfers the files and sync's the Pallet and printer
• I did the Chroma install so I could use Prusa Slicer because it is far better than Mosaic's solution
• I changed my heat break to one that isn't stepped because my understanding is that was installed specifically for the MMU2

If you aren't sure about anything, keep asking here.....lots of great knowledge and help.

A question, what power supply do you have? the older silvery one or the newer black one?

RE: First thing I do tomorrow is remove the MMU2

Older silver one, my 3 (->3S) dates back to early 2019.

RE: First thing I do tomorrow is remove the MMU2

^^ Is there any significant difference between both, apart from the looks and mounting points?

RE: First thing I do tomorrow is remove the MMU2

I am also going to disable it as well.

Its getting way too frustrating to continuously re-calibrate the sensors and all the other tinkering just trying to get filament to load.

RE: First thing I do tomorrow is remove the MMU2

My MMU2S is arriving ... soon.  Tracking says it was scheduled to be here yesterday but I probably won't get it until Monday.  No matter, I don't think I'm going to assemble and install it right away.  I'll wait a couple more months.  Hopefully they'll get the bugs worked out and release an upgrade kit before then.

I bought it to be able to mix tpe and pla, but I don't trust it to load and unload tpe 200 times in a row without failure.  It would be nice to do a couple multi-color pla prints, but I don't really have anything specific in mind.  I think the MMU will be more hassle than it's worth.  When I ordered it I didn't realize how unreliable it was.
