Should You MK3.5??? - Prusa MK3S+ to MK3.5 Upgrade - Prusa Upgrade - Chris's Basement - 2024 

I'm glad you are happy with it! Thanks

Likewise !

Thanks!

That's great! Thanks for watching

Definitly a good alternative. Or you might use an external pad with klipper to controll multiple mk3s+. However, if it comes to ease of use, imho the 3.5 upgrade is an valid upgrade alternative. Esp. if you also want to add the MMU3. The advantage of the mk3.5 upgrade is everything is dialed in by Prusa. Esp. between Prusa Slicer and the mk3.5. On klipper you might spend more time to optimize profiles. Setting up an MMU is even more tricky. Which is O.K. for tinkering as a hobby. However, if you primary want to print, the mk3.5 upgrade is preferable. However, the Prusa Mini Board/Display (+external Mosfet for the bed) might be an alternative. As both board and firmware are open source an both mk4 and Prusa share the same firmware base now, you might edit the firmware for the mini hardware to the mk3 values, if you do not need the MMU. You get board+display for the mini for about $70 on Aliexpress...

Does the zero 2w have the processing power for input shaper calculations, or am I thinking of the camera that it has issue with.

⁠@@rembrantsworkshop It doesn’t have problems with neither of those. The Zero 2 W is enough to run 2 Voron trident with input shaper and webcams in both(maybe more, but those 2 are the ones I’m currently using) . The original Zero is the one that struggles because of the cpu. The 2W is basically Rpi 3b with less RAM. The original one was really underpowered.

@@valen961 ah thank you.

@@rembrantsworkshop The Pi 02W is basically a Pi3 but with half the memory and 70% of the CPU clock and 1 USB instead of 4. Cameras are said to be fine but fancy graphing software for setting up input shaping might be better run elsewhere. The 02W's are commonly used for Klipper or Octoprint and are a major step up from the old Pi 0W in processing performance due to quadcore vs single core.

Happy to help! Thanks for watching

That is true, that is an awesome feature. I'm sure I forgot a lot of them.

I have reached out but, I haven't heard anything back. ¯\_(ツ)_/¯

Glad I could help! Thanks for watching

Thanks Sergio! See you Saturday?

Thanks for watching!

Absolutely! This upgrade may not be worth it on older Prusa machines

I hope that gets added back soon.

Thanks Zimmy!

Nice! I love all the little features it adds to the machine.

It's definitely up to the user and their individual needs. Thanks for watching

Thanks! I hear that, with some setups, like the one you list, I wouldn't mess with success.

Thank you! I have done these before, check this one out. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nDwW3eNxp2k.html

@@ChrisRiley Thanks for the link, it was great. I forgot to tell you that I am running Mainsail not Octoprint. Is the installation process the same using Kiauh?

Yes, same process, just select which one you want.

Ain't nothin' wrong with that! Thanks for your input!

I'm glad your happy with it! Thanks for your insight

Yay, Team Liberty!

That is a great tip, I do this my self on some parts.

Thanks! We subscribe to a video creator site called Artlist. The music is from there.

That's a great idea!

Thank you! Good luck with your projects!

@@ChrisRiley I did end up upgrading, and I’m very happy with the results.

🙂👍 Thanks for watching!

💯

I totally get it! That Revo is a great hotend

Im seriously thinking of goin back to the nylock mod I had working before the 3.5 upgrade,,,,now where did I put those nuts?

@@darco63 I wonder if the Prusa bed leveling plugin for octoprint works with the new setup yet. You'll definitely need to at least use the mesh output to dial it in if it isn't. I'm not disappointed I left my nylon lock nuts in place. Seems like just an easy way to help the printer with it's first layer.

I need to do some testing with and with out them. I will see if I can get this done soon. These are the nuts. www.prusa3d.com/en/product/expansion-joints-set/

No, I haven't done anything in that yet.

Space might be an issue for a lot of people.

Thanks Dave! Two is always faster and who doesn't need another machine. :)

Thanks! I haven't heard anything, but they should work on all the firmwares. I will look into it further.

@@ChrisRiley Just wanted to give an update upgraded to mk 3.5 with ease. I went and bought the x and y axis motors for the mk 4 and installed them but had a constant failure for both x and y axis during initial calibration. It appears that there is some 1.8 degrees changes in the firmware itself that prevents them from working correctly.

Thanks for watching!

I agree 💯 Thanks for your insight!

This upgrade isn't for everyone. It may not be worth it on older Prusa printers

No 3.9 but 4.0 is in the works!

It uses 2130's and they do get really hot. You can give it a try, but you might want to add some heat sinks.

🙂👍

Oh wow! I didn't know that, this is great information for folks to have.

Hmmm, I also have a Bondtech extruder. Are there any other gotchas ?

@@johnpeters4214 The other thing I noticed is that the SuperPINDA probes partially off the right side of the bed. My bed has always been closer to the left side of the frame opening than right. The initial setup no longer looks for the target points on the bed so it doesn't compensate for the misalignment. This results in some extra "squish" if I print close tot the right side of the bed.

@@johnpeters4214 I'm using OctoPrint & send gcode script "After serial connection to printer is established" to correct the E-steps.

Which Bondtech extruder? The MK3s or LGX? I currently have a MK3s+ with Mosquito Magnum which has different stepping than the LGX version.

I hope to do a lot of what you are suggesting here with the bear build we are currently working on.

Thanks! No, I'm afraid they will have to be re-sliced to up the speeds.

Thanks for sharing!

If the printer works, don't mess with it I say.

Someone listed it here, looks like you need to use the start gcode to change the steps for the bondtech.

It's usually the mosfet that is causing an issue like this. Boards are very inexpensive now, I would replace it.

Thanks for watching! I appreciate your insight!

👍🙂

That's a great point! Thanks for watching

I hear you 100%. A 0.6 have a config out of the box, so you should be able to use it as is if you converted to 3.5

The Prusa board does not support camera. But for simple preview, an ESP32cam might be enough (just 640by480, but less than $10 and using webcam, not IPcam protocoll, so directly viewable in any browser).

👍🙂

💯

Sweet!

Huh, that's odd, sounds like a bug. Maybe try the bugfix version to see if it's been resolved.

Many thanks for your prompt reply, will give it go over the weekend, regards Rob,

Interesting, what issues does the LGX solve for you?

@@ChrisRiley better print quality overall

It doesn't actually, I think it might even be quieter some how.

There are extra things you have to do in the start gocde to get the different extruders to work.

@@ChrisRiley Bondtech usually includes the extra things in their firmware...I'm mainly concerned on if they have firmware for their hot end and the new 32 bit board.

@@InspGadgt Yeah, no support from Bondtech for 3.5 that I know of yet.

Yes. I went to 3.9 and am also using Octoprint with no problems

3.5 also still Works with octoprint

Yes, as others have said, octoprint is all good.

Thanks for your insight!

I have a couple Prusa Bears running on SKR 1.4 & 1.4 Turbo with Klipper. They are pretty close to the same as my MK3.5 upgrade but have z auto level which is an enhancement that the 3.5 can't do.

Interesting

If you have an older Prusa model, the upgrade probably isn't worth it. 🙂

That's strange, I'm on 6.0. Try updating Slicer

@@ChrisRiley Yeah i've been using some pre update g-code, maybe that is making the difference.

Good luck with your projects!

I reaaly Like the Touch and ITS really Fluid, maybe you got a Bad one?

@@MaxMichel89 part of it is that the interface is too damn small. That certainaly doesn't help.

Thanks for your insight!

I'm glad your happy with your MK4! Yeah, if you have an older Prusa, the upgrade may not be worth it.

@@ChrisRiley MMU3 is done, the required nextruder mod will probably happen tomorrow. Unlike building the MMU3 itself, I can't mod the printer on the couch. LMAO (and yes I lost a bearing at one point, but I found it LMAO)

Totally agree!

Thanks for your insight!

Faster is straight up better all around. You can get to a place where you exceed your hotends ability obviously but this idea that slow is better isnt actually based on anything but gut feeling. Like many things in life you push till yoy hit a bottleneck and going slower than that is just a waste of potential.

Thanks for watching

Thank you for your insight!

Too bad Bambu is closed source.

@@ChrisRileyThey print objects quicker and with better surface finishes than Prusa and do it cheaper. That’s all I require to make money from them. 🤷🏼‍♂️

​@@ChrisRileyPeople say this, but how true is it really. That sounds silly at first, but look at Prusa's current stances on open source and their actions. My take: Prusa is open source where they have to be and only technically speaking. Obviously that requires further explanation so to put it succinctly: Prusa Slicer: Based on much gpl code. No way they could go closed without rewriting from scratch and theyve complained about it being forked which is ridiculous as they forked slic3r themselves. Prusa firmware: Marlin, but in a way that makes it difficult to merge their work back into marlin proper and vice versa because its a very different, custom, old version which I think is a big reason input shaper came so much longer after marlin had it. Hardware: They haven't released hardware source like step files, gerbers or boms for their last 2 printers and have openly said they make their boards difficult to replicate defeating the purpose of being open source in the first place. Long and short, Prusa uses open source all over their branding but when it comes down it, they are only a bit more open than the elephant in the room.

​@@BeefIngot Here's where I'm at, do you want to use your 3D printer as a hammer? Meaning, it gets the job done. Do I care if my toaster is open source? Please, do what you want, I would never stop you or look down on you for making awesome things, no matter what tool you use. My channel is based on a community. The 3D printing community that I know and love is based on the sharing of ideas. Prusa is not perfect, being open source makes it really hard for anyone to compete, but that isn't an excuse. I don't get paid by any 3d printing company. All I want is to see people and companies come to the table and participate. Open source is extremely important and it has gotten our community to where it is today. The rules of it are really hard to follow. I do my best to instill the values of open source because great things can come of it. In my book, again personal opinion, there is a difference between companies that fear giving away everything they have worked so hard for and companies that use all of that work and then turn to spit in our communities face. The average user wouldn't even know, but my family, this community does.

@@ChrisRiley I get the sentiment, I think if I put what I was saying differently it would be that I feel like projects like ratrigs, vorons, vzbots more accurately represent open source while Prusa hasnt really since the early stages of the mk3. I suppose more open source is better than less, and I get that perspective, but to me and I do appreciate being able to have different opinions, If I want an open printer Ill build one and if I want a tool, well thats currently Bambu. Its the elephant but I ultimately think they pushed the needle forward and respected licenses which is above the vast majority of 3d printer manufacturers. I would love if other companies pushed user experience as hard as they do, but they just dont seem to and Prusa seems to be tripping over their laurels at least for now. That said, I get the sentiment, the feeling like what was once basically always open (at least in the consumer space) now isnt (though Creality has shown its only due to laziness multiple times.... but thats another story...). I feel that happening all over like a tide. All that said, I get that pragmatically, building any of the truly open source projects I mentioned is big work; even something like the rook is big work, so I can get Prusa coming across as a middle ground between the 2 ends. Also, I lowkey totally get the fear of Bambulabs doing what DJI has for drones, though that can only happen in a space where other companies repeatedly continue not to get that the big advancement is actually user experience rather than just speed. Unlike DJI, at least right now, they arent patent heavy, so I think there is a chance for coexistence if companies just test things for ux before sending them out for once or like prusa used to be a great example of.

I guess time will tell.

Thanks for your insight!

Too bad Bambulab is closed source

I black really shows the imperfections.

You bet! To each their own
