I want to buy MMU3 for MK3.5S, but there is no option at the shop
As the title says, I want to buy an MMU3 for my MK3.5S, but the store only has the options for “MK3.9S / MK4S” and “MK3S+”, with the option for the “MK3S+” being sold out.
A google search led me to the site “ https://www.prusa3d.com/de/produkt/original-prusa-mmu3-upgrade-kit-for-mk3-5s-mk3-5-8/ ”, but it no longer exists.
Prusa's chat referred me to the same page, but when I said that it no longer existed, he didn't really know what to do.
Did I miss something, that there is no MMU3 for the MK3.5S anymore?
RE: I want to buy MMU3 for MK3.5S, but there is no option at the shop
I'm here to figure this out. I chatted with support from Prusa and they were very confusing, linking me to a list of parts needed to update a MMU2 to an MMU3.
RE:
Seems like Prusa doesn't supply the MK3S+ hotend upgrade parts in the kit anymore, but the files needed for the MK3S+ hotend update are on Printables and some individual parts are available for sale. You would need the MMU3 kit and then print the MK3S+ hotend update parts. The instructions for the MK3S+ update are still in the MMU3 assembly instructions. See https://www.printables.com/model/531604-mmu3-printable-parts/files for the MMU3 parts. There is an MK3S+ section with the parts you need to print for the hotend updates.
You need to find the insert for the "Chimney-Base" or just buy the Chimney-Base from Prusa with the insert in it. https://www.prusa3d.com/product/chimney-base/
I would also replace the PTFE tube in the hotend if you have many hours on the printer. That is part of the MMU3 instructions for the MK3S+ hotend update.
I upgraded my MK3S+ for the MMU, but it is now an MK4S.
I hope this helps
RE: I want to buy MMU3 for MK3.5S, but there is no option at the shop
Thank you this was really helpful, so the main discriminator is just making sure that I can upgrade the MK3S+ hotend following the steps in the instructions for that and can just order the MMU3 for MK4S and be ok?
Why couldn't support just explain that??
