Reliability of MK3.5 with MMU3  

RE: Reliability of MK3.5 with MMU3

It looks like MMU3 is supported on a MK3.5S but.... not a lot besides that... 

Maybe not a lot of people doing this? I have tons of questions on this topic, like MMU3 profiles for MK3.5S and reliability as well, but no one talks about it...

I would just skip this and whenever Prusa announces an upgrade path from 3.5S to 4S just do it... It looks like even on a MK4S + MMU3 some people are finding reliability issues as well, much less, but if you search for it you can find it. 

On the other hand, TONS of reports from other people stating no issues with their MMU3 and their MK4S

Sorry for my english, but, i cant finish many of my prints because filament jam (or clog) in the nozzle with the standar profiles of 0.2mm hight SPEED and profile printer of Mk3.5 + MMU3

material PLA (printalot) 1.75mm in 1kg package.-

But, if i turn off the MMU unit, and send to print with the standar profile of MK3.5 and 0.2mm speed,the print finish flawless.

 

I need support, i need to understand why this had occured and how i resolve.

best regard from argentina.

Did you get this resolved? 

I've been running Mk3.5 and now Mk3.5s with an MMU3 successfully. I used to have a similar jamming issue when the extruder was trying to unload filament. It ended up being a worn out hotend PTFE tube. The inside diameter was too large and not properly forming the filament tip during unloading causing jams.
