Upgrade path from MK3.5 to MK3.9s ?
I have a MK3.5 currently (and also a MK4). I do like the Nextruder on the MK4 as the nozzle swap is so much easier and efficient. The perfect first layer is also fantastic, then there is the huge weight reduction due to using a pancake motor, that lone will help with residence reduction as it doesn't have so much weight to stop and move in the other direction.
Due to these reasons, I wanted to know if there was a path to upgrade from the MK3.5 to the MK3.9, essentially the Nextruder (as the xBuddy board and LCD were done with the 3.5 upgrade). I didn't see this as an option when looking at the MK3s+ upgrades as it shoots straight to 3.5s or 3.9, then 4s but nothing between these.
Let me know if there is something available.
*NOTE to Prusa team - it might be a good thing to add to the upgrade options, then those folks like myself can upgrade a little at a time or as needed (its more cost effective for some folks like myself to do it in smaller hops vice all at once).
RE: Upgrade path from MK3.5 to MK3.9s ?
Hi,
I am in the exact same situation: MK4S + a MK3.5.
And since the Nextruder is so convenient on the MK4S, I also want to upgrade my MK3.5. So far I did not find any possibility to do that.
Some forum members suggested to sell the MK3.5 and buy a new MK4(s), but I do not want to do that. I also do not want to buy the MK3S -> MK3.9S/MK4S upgrade kit (for that price + the already spent MK3.5 upgrade I could have easily bought a Bambu 🙂 ). Joke aside.
Like OP already mentioned, the xBuddy board and screen are already upgraded. Adding an option for the Nextruder upgrade would be much appreciated.
So count me in, if there is a way to upgrade the MK3.5 to MK3.9(S) or MK4(S)
Best regards,
Armin

Another 3.5 owner interested in an upgrade path to a 3.9S (or 4S).

Yes I'm interested in an upgrade path to a 3.9S (or 4S).
RE: Upgrade path from MK3.5 to MK3.9s ?
In looking at the upgrade path from a MK3s+ to 3.5 (buddy board/LCD) it is for $249, and the upgrade path from a MK3s+ to 3.9 (buddy board/LCD/Nextruder) it is $499. So ideally the Nextruder should be priced around $249 to close the gap between 3.5 to 3.9.
The main idea behind this threat is to allow for a more gradual upgrade path. Essentially allowing folks to upgrade a little at a time, as they may not be able to afford the larger jump all at once. It still comes out to same price point in the end, just gives those of us some more flexibility in doing it in smaller increments.
Thanks everyone for posting your comments showing interest. Hopefully Prusa will read about this and consider offering this as an option.
RE: Upgrade path from MK3.5 to MK3.9s ?
I too would love this option to be added. MK3.5s to MK3.9s or MK4s with out having to buy the entire kit for $499 to go from MK3 to Mk3.9/mk4.
Why is this not an option. Prusa is always talking about their customers and how they will always make parts available and will not leave customers stuck but it looks like that is not the case. Either you spend the additional $499 and waste all the parts from the Mk3 to Mk3.9/Mk4 or you buy a whole new MK4 and waste an entire printer. Come on Prusa take care of you customer by adding this other upgrade option.. Why not add the other upgrade option.
Come on Prusa, Please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
RE: Upgrade path from MK3.5 to MK3.9s ?
I would also like to do it.
Evan up to 4s.
They just need a parts box as all the paper work is on line.
RE: Upgrade path from MK3.5 to MK3.9s ?
I would also like an option to upgrade my 3.5 to the 3.9 or the 4.0, I have a MK4, and a Mini already love the MK4 always prints no problems, just want to upgrade my 3.5 now. (PLEASE)
RE: Upgrade path from MK3.5 to MK3.9s ?
Another voice asking for the same thing. I had upgraded my mk3s+ to the 3.5, and then later bought a mk4s kit. The nextruder with the load cell has spoiled me and now I wish I had gone with the 3.9 upgrade instead. It's frustrating that the 3.5 kit has ended up being a dead end in terms of upgradability. Prusa, please make a 3.5 to 3.9 kit. I'll even pre-order it.
RE: Upgrade path from MK3.5 to MK3.9s ?
I contacted Prusa yesterday, even taking out the most expensive parts from the MK3S -> MK3.9S kit that were already in the MK3.5S kit (e.g. xLCD, buddyBoard) seems to be an impossible mission for them.
Obviously they will be wondering whether to make the kit.... someday, maybe.
They totally don't care if I buy from them (parts, printer) or elsewhere. An interesting strategy at a time when competition is getting better and better.
RE: Upgrade path from MK3.5 to MK3.9s ?
Do we have any updates from Prusa on this topic.
I upgraded my MK3S+ to a 3.5S and wow, it is already amazing, but in order to use MMU3 (reliably, according to many reports), the 3.9 is a wayyyyyyyy more reliable way to implement MMU3 (or the MK4S).
Is there an upgrade path from MK3.5 to MK3.9 or MK4S? Even if it is a blog post with all the instructions and parts we should get for the upgrade, it would be very very amazing!
I almost got into the Bambu trap, I'm glad I revisited the idea of upgrade my MK3S+ (but I guess I picked the wrong upgrade choice at the time by going to the MK3.5S)
RE: Upgrade path from MK3.5 to MK3.9s ?
Anyone from Prusa monitoring these forums?
RE:
No, they don't in general, this is a User-to-User forum. I haven't come across a list of the parts required (probably as they will be quite a lot). There'll be the whole of the Nextruder (new e-motor and nozzle as well), new rods for z-axis, new belts for X & Y, if you don't have the S version of the MK3.5 then you'll also need the new Wi-Fi module and the new NFC set, new cables and various fasteners... and that's just what I can spot with a quick look through the sales pages!
I would suggest using the Live Chat on the e-Shop's web page and ask them.
RE: Upgrade path from MK3.5 to MK3.9s ?
I guess pretty much all we need , from a documentation perspective, will be in the documentation from MK3S+ to MK4S. What would be great is for Prusa to create the kit, so we only by what we need to go from MK3.5S to MK4S. Either the kit or a list of items in a blog post.
RE: Upgrade path from MK3.5 to MK3.9s ?
Same question, would love to upgrade from MK3.5 to the Nextruder version
